Abstract:
Most classifications of reservoirs, seals and source rocks based on the ability of the rock to generate, accumulate and preserve hydrocarbons, and the genesis of rocks is not always taken into account. The article presents a ranking scheme for continental, coastal-marine and marine sedimentation environments that determine the genesis and properties of the basic criteria of petroleum potential – source rocks, reservoirs, seals and pinch-out traps. Rocks, which can consider as source rock, reservoirs and seals are formed in each depositional environment. However, their structure, mineral composition and distribution area will differ from each other depending on the sedimentary environment and conditions. A combination of elements of the hydrocarbon system formed, corresponding to the sedimentation environment and are characteristic for basins of various types. Continental environments are favorable for the formation of reservoirs and local seals, while the accumulation of source rocks limited by lacustrine, floodplain, and swamp facies. The coastal-marine environment is favorable for the formation of all the basic criteria of petroleum potential, and the transgressive-regressive cyclicity determines the interbedding of source rocks, reservoirs and seals in the section. The marine depositional environments are most favorable for the formation of regional seals and source rocks, including high-carbon formations. The proposed ranking scheme of sedimentary environments and the basic criteria of petroleum potential genetically related to them is applicable in system analysis and selection for analogues of petroleum system elements in sedimentary complexes formed in similar depositional environments.

Abstract:
Four Lower Cretaceous sections in the southern Yazd Block were measured and studied to interpret the palaeoenvironments, synsedimentary tectonics, and sequence stratigraphy. The Early Cretaceous sedimentary record of this block, consisting of the Sangestan, Taft, Abkuh, and Darreh Zanjir formations, was mainly influenced by synsedimentary tectonic activities in a tectonically unstable basin. Field observations and laboratory studies were used to identify lithofacies and microfacies, based on which six depositional environments were identified: upper coastal plain (alluvial fans), shore, tidal flat, lagoon, shoal, and open marine. A carbonate-siliciclastic shallow platform including an alluvial-coastal plain and an inner platform is suggested for the depositional environment of the Sangestan Formation. The depth of the overall shallow sedimentary basin of Sangestan Formation increases from west to east and deposition was controlled by long- term sea-level changes. A carbonate platform consisting of inner and outer parts, including tidal flat, lagoon, open marine belts, is suggested for the depositional environment of the Taft and Abkuh formations, while the Darreh Zanjir Formation accumulated in a deep basin. The predominant facies demonstrate an overall transgression-regression cycle (the 2rd order cycle) during the depositional time of these formations in the southern Yazd Block.

Abstract:
Estuaries are one of the major sub-environments of the coastal zone wherein freshwaters interact and mix with saline waters, and facilitate deposition of finer sediments, organic matter, and metals. Intertidal mudflat and mangrove sediment cores collected from estuaries along the central west coast of India were investigated for various sedimentological and geochemical parameters to understand the changes in the sedimentary depositional environments and various factors influencing the processes. Additionally, estuarine biota was examined to understand the bioaccumulation of metals with respect to bioavailability. The results indicated considerable changes in the depositional environments with time owing to sea-level changes; geomorphology of the estuaries; rainfall and river runoff; anthropogenic activities including construction of dams and bridges. The sediments in the estuaries are considerably polluted by metals and pose toxicity risks to the estuarine biota due to high metal bioavailability. Marine gastropods and mangrove plants act as prospective bio-indicators, and the bioremediation potential of mangroves for contaminated sediments was identified. Metal bioaccumulation in edible benthic biota can be harmful to the human health.

Abstract:
Abstract Often analyses of depositional environments from sparse data result in poor interpretation, especially in multipartite depositional settings such as the Niger Delta. For instance, differentiating channel sandstones, heteroliths and mudstones within proximal environments from those of distal facies is difficult if interpretations rely solely on well log signatures. Therefore, in order to achieve an effective and efficient interpretation of the depositional conditions of a given unit, integrated tools must be applied such as matching core descriptions with wireline log signature. In the present paper cores of three wells from the Coastal Swamp depositional belt of the Niger Delta are examined in order to achieve full understanding of the depositional environments. The well sections comprise cross-bedded sandstones, heteroliths (coastal and lower shoreface) and mudstones that were laid down in wave, river and tidal processes. Interpretations were made from each data set comprising gamma ray logs, described sedimentological cores showing sedimentary features and ichnological characteristics; these were integrated to define the depositional settings. Some portions from one of the well sections reveal a blocky gamma ray well log signature instead of a coarsening-upward trend that characterises a shoreface setting while in other wells the signatures for heteroliths at some sections are bell blocky in shaped rather than serrated. Besides, heteroliths and mudstones within the proximal facies and those of distal facies were difficult to distinguish solely on well log signatures. However, interpretation based on sedimentology and ichnology of cores from these facies was used to correct these inconsistencies. It follows that depositional environment interpretation (especially in multifarious depositional environments such as the Niger Delta) should ideally be made together with other raw data for accuracy and those based solely on well log signatures should be treated with caution.

Abstract:
Particle morphology is an important feature of sediments that reflects their transport history and depositional environment. In this study, we used dynamic image analysis (DIA) to measure the size and shape of beach sediments on the east and west coasts of Hainan Island in South China Sea. DIA is a fast and accurate method that can capture and analyze a large number of sediment particles in real-time. We extracted morphological descriptors of each particle, such as equivalent diameter, sphericity, aspect ratio and symmetry, and their distributions based on volume and number. We performed multivariate analysis on the particle morphological data, including alpha diversity, statistical analysis and fingerprint techniques. We found that the Shannon index, calculated by the number distribution of sediment particle morphology, can effectively discriminate between the two sites, reflecting different sediment sources, transport processes and depositional conditions. We also established a composite fingerprint based on seven morphological parameters and diversity indices, which can accurately distinguish between aeolian and hydraulic sedimentary environments. Our study demonstrates the potential application of DIA in identifying sedimentary environments and establishing sediment fingerprints. This can help us understand the sediment transport processes and depositional mechanisms in coastal areas.

Abstract:
The upper Permian to Lower Triassic sedimentary succession in the southern Bonaparte Basin represents a marginal marine depositional system that hosts several gas accumulations. Of these, the Blacktip gas field has been in production since 2009, while additional gas resources are under consideration for development. The sedimentary succession extends across the Permian–Triassic stratigraphic boundary, and shows a change in lithofacies from the carbonate dominated Dombey Formation to the siliciclastic dominated Tern and Penguin formations. The timing, duration, distribution and depositional environments of these formations in the Petrel Sub-basin and Londonderry High is the focus of this study. The sedimentary succession extending from the Dombey to the Penguin formations is interpreted to represent marginal marine facies which accumulated during a long-lasting marine transgression that extended over previous coastal and alluvial plain sediments of the Cape Hay Formation. The overlying Mairmull Formation represents the transition to fully marine deposition in the Early Triassic. Regional scale well correlations and an assessment of biostratigraphic data indicate that marginal marine depositional systems were initiated outboard before the end-Permian extinction event, and migrated inboard at about the Permian–Triassic stratigraphic boundary. Marginal marine deposition across the southern Bonaparte Basin continued through the faunal and floral recovery phase as Triassic species became established. The depositional history of the basin is translated to a chronostratigraphic framework which has implications for predicting the character and distribution of petroleum system elements in the Petrel Sub-basin and Londonderry High.

Abstract:
The Sudanese red sea coastal plain is geologically characterized by Cenozoic siliciclastic and shallow marine rift related sedimentary se-quences. Pliocene-Pleistocene is represented by the thick older gravel unit and the emergent linear reef terraces. In this study, wire line logs besides the investigations of cutting samples were used to investigate the un cored facies successions, to detect changes in grain size distribution, lithology and sedimentary facies and hence to interpret depositional environment. Confirmation of the log behavior using the cores and the cutting samples was undertaken. Furthermore, core to gamma-ray and spontaneous potential log correlations were set up. The lithofacies association and the depositional patterns of Zeit Formation were controlled by allocyclic and autocyclic processes, which include tectonic, palaeo climatic as well as depositional mechanisms. The lithofacies Distribution of Lower Zeit Member shows the southwestern part of the area is dominated by terrestrial to marginal marine partly supra tidal domain where some channel feeders can support the sand distribution from south to north. The central part of the area is dominated by shallow marginal marine to partly supra-tidal domains. The Middle Zeit Member was dominated by marginal marine to supratidal domain. The Upper Zeit Member repeated pattern of facies distribution being similar to that of Middle Zeit, however the sandy facies influxes increased towards the S. Suakin, Digna- area, towards Bashayer area and Durwara area from south to north.

Abstract:
The early Middle Miocene Ngrayong Formation, an important reservoir of North East Java Basin, is well exposed in the central anticlinal part of Madura Island. The purpose of current study is to classify the depositional environments of the study area based on the characteristics and geometry of sedimentary facies. In the Madura island, the thicker clastics and deeper carbonates of Ngimbang Formation and Kujung Formation of Late Oligocene-Early Miocene deposited in the northeast-southwest asymmetrical half grabens. After the deposition of Kujung Formation, the basin morphology developed nearly eastwest trending shelf edge and the deposition of Tuban Formation began. The fine grained complex of Tuban Formation was followed by the Ngrayong Sandstones deposition. The depositional model of Ngrayong Formation is being producing of wide variety of depositional environments. Large scale cross-bedded sandstones and bioturbated massive sandstones with thin to medium bedded argillaceous limestone that outcrop in the northern part of the study area are deposited in costal environment. The heterolithic sandstone with planar and trough cross-lamination, fine grained sandstone with interlaminated structure and bioclastic carbonate exposed in the central part of the study area are deposited in upper shallow marine area. Dark grey siltstones and mudstones deposited in lower shallow marine area are well exposed in southern part of the study area. In conclusion, Ngrayong Formation in Madura area is developed in three depositional units which are coastal, upper shallow marine and lower shallow marine.

Abstract:
ABSTRACT The interaction of fluvial, tidal, and wave processes in coastal and paralic environments gives rise to sedimentary successions with highly varied styles of facies architecture; these are determined by the morphology and evolutionary behavior of the range of coastal sub-environments, which may be difficult to diagnose in subsurface sedimentary successions with limited well control. This study presents depositional models to account for stratigraphic complexity in a subsurface fluvial to shallow-marine succession, the Middle Jurassic Dhruma Formation, Saudi Arabia. The study achieves the following: i) it examines and demonstrates sedimentary relationships between various fluvial, nearshore, and shallow-marine deposits, ii) it develops depositional models to account for the stratigraphic complexity inherent in fluvial to shallow-marine successions, and iii) it documents the sedimentology and the stratigraphic evolutionary patterns of the lower Dhruma Formation in the studied area of Saudi Arabia. The dataset comprises facies descriptions of 570 m of core from 14 wells, 77 representative core thin sections, 14 gamma-ray logs, and FMI image logs from 4 wells. These data are integrated with quantitative information from > 50 analogous systems from a wide range of modern and ancient settings, stored in a relational database. Stratigraphic correlations reveal the internal anatomy of the succession. Facies associations are representative of fluvial channels, intertidal flats, pedogenically modified supratidal flats or floodplains, river-influenced tidal bars, weakly storm-affected shoreface and offshore-transition zones, storm-dominated delta-front and prodelta settings, and an open-marine carbonate-dominated shelf. These sub-environments interacted in a complex way through space and time. The vertical succession of the studied interval records an overall transition from coastal-plain deposits at the base to marine deposits at the top. As such, the succession records a long-term transgressive, deepening-upward trend. However, this general trend is punctuated by repeated progradational events whereby coastal sand bodies of fluvial, wave, and tidal origin prograded basinward during stillstands to fill bays along a coastline. The nature of juxtaposition of neighboring sub-environments has resulted in a sedimentary record that is highly complex compared to that generated by morphologically simple shoreface systems that accumulate more regularly ordered stratal packages.

Abstract:

Submarine-fan deposits form the largest sediment accumulations on Earth and host significant reservoirs for hydrocarbons. While many studies of ancient fan deposits qualitatively describe lateral architectural variability (e.g., axis-to-fringe, proximal-to-distal), these relationships are rarely quantified. In order to enable comparison of key relationships that control the lateral architecture of submarine depositional environments, I digitized published bed-scale outcrop correlation panels from five different environments (channel, levee, lobe, channel-lobe-transition-zone, basin plain). Measured architectural parameters (bed thickness, bed thinning rates, lateral correlation distance, net-to-gross) provide a quantitative framework to compare facies architecture between environments. The results show that sandstone and/or mudstone bed thickness alone or net-to-gross do not reliably differentiate between environments. However, environments are distinguishable using a combination of thinning rate, bed thickness, and correlation distance. For example, channel deposits generally display thicker sandstone beds than mudstone beds whereas levees display the opposite trend. Lobe deposits display the most variability in all parameters, and thus would be the most difficult to identify in the subsurface. I sub-classified lobe deposits to provide a more detailed analysis into unconfined, semiconfined and confined settings. However, the results for semiconfined lobes indicate that the degree of lobe confinement and subenvironment is not easily interpretable at the outcrop scale. This uncertainty could be partially caused by subjectivity of qualitative interpretations of environment, which demonstrates the need for more quantitative studies of bed-scale heterogeneity. These results can be used to constrain forward stratigraphic models and reservoir models of submarine lobe deposits as well as other submarine depositional environments.

This work is paired with a case study to refine the depositional environment of submarine lobe strata of the Upper Cretaceous Point Loma Formation at Cabrillo National Monument near San Diego, California. These fine-grained turbidites have been interpreted as distal submarine lobe deposits. The strike-oriented, laterally-extensive exposure offers a rare opportunity to observe bed-scale architecture and facies changes in turbidites over 1 km lateral distance. Beds show subtle compensation, likely related to evolving seafloor topography, while lobe elements show drastic compensation. This indicates more hierarchical method of compensational stacking as the degree of bed compensation is small compared to the degree of element compensation. Thinning rates and bed thicknesses are not statistically different between lobe elements. This signifies that the lateral exposure is necessary to distinguish lobe elements and it would be extremely difficult to accurately interpret elements in the subsurface using 1D data (e.g., core). The grain size, mudstone to sandstone bed thicknesses, element/bed compensation, and lack of erosion observed in the Cabrillo National Monument exposures of the Point Loma Formation are most similar to values of semiconfined lobe deposits; hence, I reinterpret that these exposures occupy a more medial position, perhaps with some degree of confinement.

Abstract:
La modélisation du sous-sol est un moyen de prédire la structure et la connectivité des unités stratigraphiques en honorant les observations de subsurface. Ces observations sont en général échantillonées le long de puits à grande échelle horizontale (kilomètre) mais à petite échelle verticale (mètre). Il y a deux types de données de puits : (1) les diagraphies, qui correspondent à des acquisitions géophysiques quasi-continus (échatillonage régulier) le long du puits (e.g., gamma ray, sonic, porosité neutron), et (2) les régions, qui correspondent à des propriétés réservoir discrètes définies par des profondeurs maximales et minimales le long du puits (e.g., biozones, zones structurales, faciès sédimentaires). Des marqueurs sont interprétés le long des puits et peuvent être associés pour générer un ensemble d'associations de marqueurs conformes, appelé des corrélations de puits. Ces corrélations de puits peuvent être réalisées manuellement (approche déterministe) par des experts, mais cela peut être sujet à des biais et ne garantit pas la reproductibilité. Les corrélations de puits peuvent également être générées automatiquement (approche déterministe ou probabiliste) en calculant à l'aide d'un algorithme un grand nombre de corrélations de puits conformes et en classant ces réalisations en fonction de leurs vraisemblances. La vraisemblance de ces corrélations de puits assistées par ordinateur est directement liée au principe de corrélation utilisé pour associer les marqueurs. Ces travaux de thèse introduisent deux principes de corrélation, qui tendent à reproduire la chronostratigraphie et les processus de dépôts à l'échelle de la paraséquence : (1) "un marqueur (décrit par un faciès et une distalité pris au centre d'un intervalle ayant un faciès constant et une distalité constante) ne peut pas être associé avec un autre marqueur décrit par un faciès plus profond à une position plus proximale, ou un faciès moins profond à une position plus distale", et (2) "plus la différence entre une interpolation chronostratigraphique (entre les marqueurs) et un profil de dépôt conceptuel est faible, plus la probabilité d'association des marqueurs est élevée". Ces deux principes de corrélation sont d'abord validés avec des solutions analytiques et appliqués sur des cas synthétiques. Ils ont ensuite été utilisés (1) pour prédire la connectivité des unités stratigraphiques à partir de données de puits sans connaissances solides sur les environnements de dépôt en inférant les paramètres de corrélation, ou (2) pour évaluer la probabilité d'un environnement de dépôt hypothétique en générant des réalisations stochastiques et en évaluant les incertitudes. Les methodes sont appliquées sur un système silicoclastique de dépôts deltaïques côtiers ciblant un réservoir du Jurassique Moyen dans le South Viking Graben en Mer du Nord. Ces travaux de thèse permettent (1) de définir deux principes de corrélation spécifiques définis par quelques paramètres qui peuvent être utilisés pour générer des corrélations de puits stochastiques dans les systèmes deltaïques côtiers, et (2) d'ouvrir la voie vers une combinaison simple de principes de corrélation spécifiques pour obtenir une meilleure caractérisation des systèmes deltaïques côtiers en évaluant les incertitudes
Subsurface modeling is a way to predict the structure and the connectivity of stratigraphic units by honoring subsurface observations. These observations are commonly be sampled along wells at a large and sparse horizontal scale (kilometer-scale) but at a fine vertical scale (meter-scale). There are two types of well data: (1) well logs, corresponding to quasi-continuous (regular sampling) geophysical measurements along the well path (e.g., gamma ray, sonic, neutron porosity), and (2) regions, corresponding to categorical reservoir properties and defined by their top and bottom depths along the well path (e.g., biozones, structural zones, sedimentary facies). Markers are interpreted along the well path and can be associated in order to generate a consistent set of marker associations called well correlations. These well correlations may be generated manually (deterministic approach) by experts, but this may be prone to biases and does not ensure reproducibility. Well correlations may also be generated automatically (deterministic or probabilistic approach) by computing with an algorithm a large number of consistent well correlations and by ranking these realizations according to their likelihood. The likelihood of these computer-assisted well correlations are directly linked to the principle of correlation used to associate markers. This work introduces two principles of correlation, which tend to reproduce the chronostratigraphy and the depositional processes at the parasequence scale: (1) "a marker (described by facies and distality taken at the center of an interval having a constant facies and a constant distality) cannot be associated with another marker described by a depositionally deeper facies at a more proximal position, or a depositionally shallower facies at a more distal position", and (2) "the lower the difference between a chronostratigraphic interpolation (in between markers) and a conceptual depositional profile, the higher the likelihood of the marker association". These two principles of correlation are first benchmarked with analytical solutions and applied on synthetic cases. They have then been used (1) to predict the connectivity of stratigraphic units from well data without strong knowledge on depositional environments by inferring the correlation parameters, or (2) to evaluate the likelihood of a hypothetical depositional environment by generating stochastic realizations and assessing the uncertainties. The methods are applied on a siliciclastic coastal deltaic system targeting a Middle Jurassic reservoir in the South Viking Graben in the North Sea.This work enables (1) to define two specific principles of correlation defined by a few parameters that can be used to generate stochastically well correlations within coastal deltaic systems, and (2) to open the path towards a simple combination of specific principles of correlation to obtain a better characterization of coastal deltaic systems by assessing the uncertainties

Abstract:
The one of the most important Eras of the Earth history, i.e. Neoproterozoic (1000-542 Ma),

was an enigmatic period characterized by the development of the first stable long-lived ~1.1-

0.9 Ga Rodinia and 550-500 Ma Gondwana supercontinents, global-scale orogenic belts,

extreme climatic changes (cf. Snowball Earth Hypothesis), the development of microbial

organisms facilitating the oxidizing atmosphere and explosion of eukaryotic forms toward the

first animals in the terminal Proterozoic. This thesis presents a multidisciplinary study of two

Neoproterozoic basins, i.e. Bas-Congo and Sankuru-Mbuji-Mayi-Lomami-Lovoy, in and around the Congo Craton including sedimentology, geochemistry, diagenesis, chemostratigraphy and radiometric dating of carbonate deposits themselves.

The Mbuji-Mayi Supergroup sequence deposited in a SE-NW trending 1500 m-thick siliciclastic-carbonate intracratonic failed-rift basin, extends from the northern Katanga Province towards the centre of the Congo River Basin. The 1000 m-thick carbonate succession is related to the evolution of a marine ramp submitted to evaporation, with ‘deep’ shaly basinal and low-energy carbonate outer-ramp environments, marine biohermal midramp (MF6) and ‘very shallow’ restricted tide-dominated lagoonal inner-ramp (MF7-MF9) settings overlain by lacustrine (MF10) and sabkha (MF11) environments, periodically

submitted to a river water source with a possible freshwater-influence. The sequence stratigraphy shows that the sedimentation is cyclic in the inner ramp with plurimetric ‘thin’ peritidal cycles (± 4 m on average) recording a relative sea level of a maximum of 4 m, with fluctuations in the range of 1-4 m. The outer/mid ramp subtidal facies are also cyclic with ‘thick’ subtidal cycles characterized by an average thickness of ± 17 m, with a probable sealevel

fluctuations around 10 to 20 m. The geochemistry approach, including isotopic and major/trace and REE+Y data, allows to infer the nature of the dolomitization processes operating in each carbonate subgroup, i.e dolomitization may be attributed to evaporative reflux of groundwater or to mixing zones of freshwater lenses. The latest alteration processes occured during the uplift of the SMLL Basin. New ages, including LA-ICP-MS U-Pb laser ablation data on detrital zircon grains retrieved in the lower arenaceous-pelitic sequence (BI group), combined with carbon and strontium isotopic analyses, yielded a new depositional time frame of the Mbuji-Mayi Supergroup between 1176 and 800 Ma reinforcing the formerly suggested correlation with the Roan Group in the Katanga Province.

In the Democratic Republic of Congo, the Sturtian-Marinoan interglacial period was previously related to pre-glacial carbonate-dominated shallow marine sedimentation of the Haut-Shiloango Subgroup with stromatolitic reefs at the transition between greenhouse (warm) and icehouse (cold) climate periods, commonly marked by worldwide glacigenic diamictites and cap carbonates. This thesis highlights that these deposists record as a deepening-upward evolution from storm-influenced facies in mid- and outer-ramps to deepwater environments, with emplacement of mass flow deposits in toe-of-slope settings controlled by synsedimentary faults. In absence of diagnostic glacial features, the marinoan Upper Diamictite Formation is interpreted as a continuous sediment gravity flow deposition along carbonate platform-margin slopes, which occurred along tectonically active continental margins locally influenced by altitude glaciers, developed after a rift–drift transition. The maximum depth of the deepening-upward facies is observed in the C2a member. The

shallowing-upward facies exibit a return of distally calcareous tempestites and semi-restricted to restricted peritidal carbonates associated with shallow lagoonal subtidal and intertidal zones submitted to detrital fluxes in the upper C2b to C3b members.

The geochemistry highlights (i) the existence of a δ13C-depth gradient of shallow-water and deep-water carbonates; (ii) the carbonate systems were deposited in oxic to suboxic conditions; and (iii) all samples have uniform flat non-marine shale-normalized REE+Y distributions reflecting

continental detrital inputs in nearshore environments, or that the nearshore sediments were

reworked from ’shallow’ inner to mid-ramp settings in deep-water slope and outer-ramp

environments, during the rift-drift transition in the basin. The pre-, syn- and post-glacial

carbonate systems could record a distally short-lived regional synrift freshwater-influenced

submarine fan derived from nearshore sediments, including gravity flow structures, which are

attributed to regional tectonic processes due to a sudden deepening of the basin caused by

differential tilting and uplifting of blocks, related to the 750-670 Ma oceanic spreading of the

central-southern Macaúbas Basin.

Combining sedimentology, isotopes and trace elemental geochemistry, the thesis highlights

that the δ13C variations in the Neoproterozoic carbonates are complex to interpret, and can be

related to: (i) the existence of a δ13C-depth gradient; (ii) the exchange between isotopically

light carbon in meteoric waters and carbonate during lithification and early diagenesis; and

(iii) isotopic perturbations due to regional metamorphism. Considering the possible englaciation of the Earth (Snowball Earth hypothesis), the Mbuji-Mayi Supergroup and West

Congolian Group seem reflected the intimate relationship between glaciations and tectonic

activity during the break-up of the Rodinia supercontinent, followed by the rift–drift

transition, and finally the pre-orogenic period on the passive continental margin.

Abstract:
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior
A análise de dados de reflexão sísmica monocanal boomer (Hz ~ 700-4,000; penetração ~ 70 ms) adquiridos na plataforma continental interna-média (até ~ 50-60 m de profundidade) ao largo do sistema estuarino baía de Sepetiba, no Estado do Rio de Janeiro, Brasil, revelou a ocorrência de uma sucessão sedimentar preservada 15-20 m, sismicamente interpretada como representando ambientes fluvio-estuarinos para marinhos rasos. Estas séries são sotopostas à inconformidade regional mais superior reconhecida na escala de plataforma, chamada superfície S3. Esta superfície é erodida por numerosas incisões fluviais, que sugerem processos erosivos associados à prolongada exposição subaérea da plataforma continental durante o estágio isotópico marinho 2 (MIS 2), globalmente datada em ~ 20 ka A.P.. A preservação de tais unidades de corte e preenchimento estuarinho presumíveis Pleistoceno Superior-Holoceno na plataforma interna-média (até ~ 30 km da costa) evidencia pela primeira vez na área a existência de um paleo sistema fluvial bastante desenvolvido e processos dominantes de denudação na bacia hidrográfica a montante que atualmente alimenta a baía de Sepetiba. Bem como que, uma série de elementos arquiteturais sísmicos dentro desta sucessão estuarina, como canais de maré retrogradantes, registram a evolução do paleo sistema estuarino de um sistema aberto à um sistema parcialmente protegido durante a transgressão Holocênica. A formação e erosão de uma sucessão de ilhas barreira isoladas e canais de maré durante a transgressão persistiu até o desenvolvimento de uma superfície estratigráfica superior na área, interpretada como a superfície de máxima inundação (MFS) no registro estratigráfico. A ilha barreira atual (restinga da Marambaia) prograda sobre a MFS como uma feição deposição regressiva, apontando para uma idade mais jovem do que cerca de ~ 5 ka A. P., idade da transgressão máxima na área, de acordo com a literatura disponível.
The analysis of boomer monochannel seismic reflection data (~700-4.000 Hz; ~70 ms penetration) acquired on the inner-mid shelf (up to ~50-60 m depth) offshore Sepetiba bay estuarine system, Rio de Janeiro State, Brazil, revealed the occurrence of a 15-20 m preserved sedimentary succession, seismically interpreted as representing fluvio-estuarine to shallow marine environments. These series overly the most upper regional unconformity recognized at shelf scale, named surface S3. This surface is eroded by numerous fluvial incisions, which suggest erosive processes associated to prolonged subaerial exposure of the continental shelf during marine isotopic stage 2 (MIS2), globally dated at ~20 ky B.P.. Preservation of such presumable Upper Pleistocene-Holocene cut-and-fill estuarine units on the inner-mid shelf (up to ~30km away from the coast) evidence for the first time in the area the existence of a rather developed paleo river system and dominant denudation processes in the upstream catchment basin that presently nourishes Sepetiba bay. As well as that, a series of seismic architectural elements within this estuarine succession, such as retrogressive tidal channels, record the evolution of the paleo estuarine system from an open to a partially-protected system during the Holocene transgression. The formation and erosion of a succession of isolated barrier islands and tidal channels during transgression persisted until the development of an upper stratigraphic surface in the area, interpreted as the maximum flooding surface (MFS) in the stratigraphic record. The present day barrier island (restinga da Marambaia) progrades over the MFS as a regressive depositional feature, pointing to an age younger than about ~5 ky B. P., dating of the maximum transgression in the area, according to the available literature.

Abstract:
AbstractTerrestrial signals in marine sedimentary archives are often used for reconstructing past environments, vegetation and climate, as well as for determining sediment fluxes, pathways, and depositional sites and changes in erosional runoff. It is therefore important to understand the origin, transport, and depositional processes of the various terrestrial sedimentary components in a depositional system. In this chapter, we use examples from southern Africa to show how source-to-sink studies have led to a clearer interpretation of downcore proxy records. Twelve rivers in four river catchment areas of various scales and in distinct climatic settings and geological formations are included in this compilation. We also discuss studies from the current-swept South African east coast, the broad western and southern margins, and investigations from protected marine embayment settings. We consider a large suite of commonly used proxies (plant wax isotopes, elemental composition, and fossil pollen) as well as hydroacoustic surveying techniques (PARASOUND and multibeam bathymetric profiling). Sampling strategies and sample types that may be used in catchment analyses are discussed. Challenges and limitations of the above-mentioned approaches are outlined. In conclusion, we underline the importance of a thorough source-to-sink approach to paleo-environmental reconstructions using terrigenous proxies.

Abstract:
The Centralian Superbasin (CSB) is a ~ 2 million km2 Neoproterozoic to early Palaeozoic (ca. 850−400 Ma) intracratonic depositional system, which stretches across four states (WA, NT, SA and QLD) and is of fundamental scientific and economic significance to Australia. Sedimentary sequences within the CSB, comprising the Amadeus/Warburton, Georgina and Officer Basins, record a critical phase of Earth history, encompassing the Neoproterozoic rise of atmospheric oxygen, major reorganisations in the global carbon cycle and the emergence of the first complex life.

Abstract:
The late Carboniferous to Middle Triassic Cooper Basin is Australia’s premier onshore petroleum province hosting a range of conventional and unconventional resources (Hall et al., 2019). Despite being considered a mature petroleum basin with over 1900 wells drilled and over 104,000 km of seismic surveys shot (Resources, 2022), many aspects of the Cooper Basin remain enigmatic with very different structural and sedimentary histories between the eight troughs and intervening ridges (Kulikowski et al., 2022).

Abstract:
The accelerating Arctic cryosphere decline severely impacts the land on which northern communities live through the presence of coastal and marine geohazards and coastal erosion, which further places the cultural heritage of coastal archaeological sites at risks. Sea ice decline also compromises the formation of polynyas, with unknown consequences for the regional ecosystems. From the 10th to the 18th of July 2022, a scientific cruise onboard the research vessel William-Kennedy allowed the collection of a suite of samples and data from the marine coastal environment of Nain, Nunatsiavut. In total, 42 surface sediment samples, 29 sediment cores, 41 conductivity-temperature-depth (CTD) profiles, 13 water samples, 24 phytoplankton nets and 13 zooplankton nets were collected. The cruise allowed the deployment of 2 moorings equipped with sediment traps in Nain Bay and within deeper offshore waters. Triangulation showed that the 2 moorings were correctly placed near their target locations. Drop camera transects were deployed in Webb Bay and at the easternmost tip of Paulmp;gt;'s Island to image the seabed and study benthic habitats. Finally, acoustic sub-bottom profiling along the entire study area allowed a high-resolution characterization of the stratigraphy of the seafloor, helped identifying locations for sediment sampling and inferring geological information about the depositional environments. The material and data collected during the research cruise will be key to 1) evaluating the productivity and dynamics of small recurring polynyas (i.e., rattles) on diverse timescales, 2) assessing marine and coastal geohazards (e.g., landslides) in relation to the deglacial history of Nain, 3) investigate the seabed geomorphology in Webb Bay and linkages with permafrost and sea-level changes and 3) conducting benthic habitat characterization. Co-led by the University of New Brunswick (UNB) and Natural Resources Canada (NRCan), this cruise was done in collaboration with the Government of Nunatsiavut, Université du Québec à Montréal, Université Laval, Dalhousie University and Memorial University, and was funded by the Natural Sciences and Engineering Research Council of Canada (NSERC) and NRCan.

Abstract:
This paper reviews the Devonian-Lower Mississippian strata of NTS areas 106 and 96 lying within Geo-mapping for Energy and Minerals (GEM) Mackenzie project area and its vicinity. These strata are usually well in excess of 1 km in non-eroded sections, cropping out extensively in the Cordillera and occurring in the subsurface of adjacent Interior Plains. Major tectonostratigraphic assemblages are the latest Silurian-Eifelian platform carbonates and evaporites, the latest Eifelian-Frasnian basinal mudrocks with isolated carbonate banks bundled in the Horn River Group (HRG), and the thick coarsening-upward siliciclastic succession of Frasnian-Tournaisian age deposited in the distal setting of the Ellesmerian foreland basin. A major total petroleum system of the HRG defines the economic prospectivity of Devonian strata. Review of the lithostratigraphic nomenclature is supplemented with highlights on HRG depositional environments, patterns of thermal maturity, disconformities, and sedimentary cycles in platform carbonates.

Abstract:
The Rush Valley 30' x 60' quadrangle extends southwest and west from the greater Salt Lake City–Provo metropolitan area with land use varied between public, military, Indian reservation, and private. This 1:62,500-scale geologic map will aid the proper management of land, water, and other resources. The map area lies within the eastern Basin and Range Province. Mountain ranges are composed of unexposed basement rocks overlain by exposed Neoproterozoic through Triassic rocks that are about 10.4 miles (16.8 km) thick, and by numerous Tertiary sedimentary and volcanic units (~47 to 20 Ma). The intervening valleys include bedrock covered with Miocene-Pliocene? rocks (~11 to 4 Ma) and Neogene-Quaternary surficial deposits. The map area is on the southern flank of the Uinta-Tooele structural zone. This area is in the Charleston-Nebo (Provo) salient of the Sevier fold-thrust belt and some thrust faults are exposed, but the overall Sevier belt geometry is obscured by extensive Cenozoic cover and later faulting. Following Sevier deformation, calk-alkaline volcanism occurred from several Paleogene volcanic centers (42 to 25 Ma). Extensional tectonism created the distinctive basin and range topography from about 20 Ma to the present. Early extensional basin fill includes Miocene sedimentary and volcanic rocks followed by Pliocene-Holocene surficial deposits primarily from lacustrine and alluvial depositional environments. Valley areas were covered by late Pleistocene Lake Bonneville, and deposits are associated with three levels of regional shorelines. Normal faults cut the ranges and are known to bound some valley margins where not concealed. Although deep drill hole data are relatively sparse, gravity data were used to help constrain basin geometries.

Abstract:
Originally designated as a national monument in 1923, Bryce Canyon National Park (BRCA) is recognized for its exceptional pink-orange hoodoo landscapes. Its iconic hoodoos, consisting of the Paleocene?Eocene Claron Formation, are only part of the geology of BRCA, which includes a nearly uninterrupted sequence of Late Cretaceous Western Interior Seaway evolution and diverse depositional environments from approximately 100 to 77 million years ago. This sequence consists of the coastal Naturita Formation, the marine Tropic Shale, the transitional Straight Cliffs Formation, and the terrestrial Wahweap Formation. These strata, and the Claron Formation, preserve diverse paleontological resources. Fossils at BRCA have received little visibility for most of the park?s history, despite relatively rapid advances in the study of Late Cretaceous and Paleogene paleontology in neighboring public lands, especially Grand Staircase-Escalante National Monument (GSENM) to the east. The best documentation of paleontological resources at BRCA was produced through concerted field inventory of the park conducted by Dr. Jeff Eaton and several cohorts of interns and students from 1988 to 2015. In that time, Eaton?s team documented nearly 200 paleontological localities within the park that yielded clams, snails, fish, frogs, turtles, lizards, snakes, crocodilians, dinosaurs, and mammals from the Straight Cliffs and Wahweap Formations and invertebrates, plants, and trace fossils in the Claron Formation. Eaton?s survey resulted in several publications, including the description of new microvertebrate species from the Straight Cliffs and Wahweap Formations. Despite this body of work, the park did not develop an internal paleontological resources management program. A new paleontological resources program at BRCA was advanced in response to construction activities that impacted several fossil localities in the Wahweap Formation. Newly hired paleontological staff conducted two seasons of field inventory (2022?2023), relocating as many of Eaton?s sites as possible and recording new fossil occurrences along the way. In this timeframe, BRCA paleontologists encountered more than 150 localities. They also conducted detailed literature review, examined the park?s paleontological collections data, and cultivated partnerships with outside researchers to better comprehend the current state and future potential of the park?s paleontological resources. This document synthesizes the total current body of knowledge on paleontological resources at BRCA to create a comprehensive paleontological inventory report. It combines historical data from the scientific literature, previous work conducted in the park, and recent fieldwork to cover BRCA?s geologic history and fossil diversity and the history of paleontological study, education, and resources management in the park.

The best documentation of paleontological resources at BRCA was produced through concerted field inventory of the park conducted by Dr. Jeff Eaton and several cohorts of interns and students from 1988 to 2015. In that time, Eaton?s team documented nearly 200 paleontological localities within the park that yielded clams, snails, fish, frogs, turtles, lizards, snakes, crocodilians, dinosaurs, and mammals from the Straight Cliffs and Wahweap Formations and invertebrates, plants, and trace fossils in the Claron Formation. Eaton?s survey resulted in several publications, including the description of new microvertebrate species from the Straight Cliffs and Wahweap Formations. Despite this body of work, the park did not develop an internal paleontological resources management program. A new paleontological resources program at BRCA was advanced in response to construction activities that impacted several fossil localities in the Wahweap Formation. Newly hired paleontological staff conducted two seasons of field inventory (2022?2023), relocating as many of Eaton?s sites as possible and recording new fossil occurrences along the way. In this timeframe, BRCA paleontologists encountered more than 150 localities. They also conducted detailed literature review, examined the park?s paleontological collections data, and cultivated partnerships with outside researchers to better comprehend the current state and future potential of the park?s paleontological resources. This document synthesizes the total current body of knowledge on paleontological resources at BRCA to create a comprehensive paleontological inventory report. It combines historical data from the scientific literature, previous work conducted in the park, and recent fieldwork to cover BRCA?s geologic history and fossil diversity and the history of paleontological study, education, and resources management in the park.
