Abstract (sommario):

Not all archaeological remains cause discussions concerning stratigraphy. In Sweden, for example, intense stratigraphy discussions have taken place among archaeologists working mainly with urban sites (see e.g. Larsson 2004), and many of the illustrative examples in the text by McAnany and Hodder are rather well-preserved remains with complex stratigraphic sequences. This is, of course, due to the fact that different remains are stratified to different extents and are thus valued differently regarding this issue. Poorly preserved, sketchy remains scattered in the ground may lack complex stratigraphic relations and are regarded as less relevant for this discussion. However, all archaeological remains have some stratigraphical relation and – as McAnany and Hodder mention – interpretation of stratigraphic sequences is a part of archaeological identity. A greater interest in how stratigraphic sequences are formed in social terms should be relevant for all archaeologists. I believe that archaeologists working with complex stratigraphic sequences, and those who work with less stratified remains, have something to gain from this discussion, but in different ways. McAnany and Hodder state that stratigraphy may be both overdescribed and undertheorized. The problem of overdescription concerns complex stratigraphies, while I think less stratified remains are suffering from a lack of discussion concerning stratigraphy all together.

Abstract (sommario):

There are controversies on the Proterozoic stratigraphic genesis, division, correlation and palaeogeographical evolution of western Henan in China. Based on the basic description of sedimentary facies, Yunmengshan and Baicaoping formation of Proterozoic typical section in western Henan is divided into 4 third-order sequences. Sequence stratigraphy framework which reflects sedimentary and overlap is established with basis of two kinds of facies-change surface and two kinds of diachrononism in stratigraphical records. Although chronostratigraphic belonging of Precambrian strata is controversial and Precambrian sequential stratigraphic study is tremendously challenging, the establishment of sequence stratigraphy framework of proterozoic Yunmengshan and Baicaoping formation in western Henan provides actual data to reshape palaeogeographic pattern of Palaeoproterozoic North China craton. What is more, it becomes a typical example of characteristics and exploration of stratigraphic accumulation under the background of tidal action.

Abstract (sommario):

New thoughts about the use of archaeological stratigraphies! Is this so? The discussion article by Patricia A. McAnany and Ian Hodder aims at the construction of a theoretical framework to expound and discuss the problems of archaeological stratigraphy. Such a theoretical framework is urgently needed, they feel, and has been largely neglected until now. Reading and interpreting an archaeological stratigraphic record, if carried out according to the guidelines they try to establish, may reveal much more information about past social processes that led to the formation of the specific stratigraphy. In the authors' own words, ‘thinking about stratigraphic sequence in social terms is more than an academic exercise’ (quoted from abstract). As the record left behind by ancient communities, archaeological stratigraphies, in their view, take a middle place on a scale from micro-records endowed with meaning (artefacts) to macro-records of contextual meaning preserved in archaeological landscapes. The in-between, the immediate residues of meaningful past human behaviour encapsulated in archaeological sites, remain, in their view, undertheorized.

Abstract (sommario):

ABSTRACTDetailed facies mapping along Lake Erie and Lake Ontario Bluffs, plus other studies illustrate that sedimentological studies, especially those with geomorphic or landform control, have had three main effects on the Wisconsinan stratigraphy of Ontario: (1) improved understanding of depositional processes and environments of several major rock stratigraphic units, without altering the stratigraphic framework, (2) aided correlation of drift sequences, and (3) questioned previous interpretations and stratigraphic correlations of drift sequences. Thus sedimentological analysis can not be separated from stratigraphy because the interpretation of depositional environnments of many mapped strata relies on their geometry and the inclusion of regional data. The geomorphic control provided by sedimentological study of surface landforms is also important because assessment of older buried sediments such as those at the Scarborough Bluffs has been hampered by the failure to determine landform control. The Late Wisconsinan stratigraphy of Southern Ontario generally remains unchanged, except for questions on the role of climate versus ice margin dynamics. The pre-Late Wisconsinan stratigraphy is scarce and not well defined, yet sedimentary studies support the presence of glacial ice in the Ontario Lake basin for all of the Middle Wisconsinan and possibly earlier, including the formation of the Scarborough delta. Large channel cut and fill sequences in the Toronto area (Pottery Road Formation), initially interpreted as resulting from subaerial erosion, were probably formed by subaqueous or subglacial meltwater erosion. If so, the pre-Late Wisconsinan stratigraphy in southern Ontario changes because the Pottery Road Formation may not be an Early Wisconsinan correlative of the St. Pierre beds. The channel example illustrates that stratigraphie correlation without sedimentological investigations may be misleading.

Abstract (sommario):

A new version of the Regional stratigraphic chart for the Ordovician of the West Siberian Lowland and the explanatory note, compiled in accordance with the Russian Stratigraphic Code, introduce changes, additional and specified data in comparison with the previous (first edition) chart. Since 1998, the stages of the Ordovician chart were changed completely. New stages – Tremadocian, Floian, Dapingian, Darriwilian, Sandbian, Katian and Hirnantian were adopted by Interdepartmental Stratigraphic Committee of Russia. The independent Regional Stratigraphic Scheme for the Devonian of the West Siberian Lowland and the Regional Stratigraphic Scheme for the Cambrian of the Pre-Yenisei Part of West Siberian Lowland were adopted. The proposed scheme for the Ordovician of West Siberian Lowland fills the lower part of the Ordovician-Silurian interval for the West Siberia. New paleontological, stratigraphical, lithological, seismo-stratigraphical data for the Ordovician of the West Siberian Lowland were obtained and generalized. For the first time independent Regional stratigraphic chart for the Ordovician of the West Siberian Lowland was compiled.

Abstract (sommario):

The paper summarises geological and palaeobotanical investigation data on Pleistocene sediments of recent decades in Lithuania and Belarus. The main problems in Pleistocene stratigraphy and correlation of sections are discussed. As a result the chronostratigraphical correlation chart of Lithuania and Belarus is presented and some changes in local stratigraphic schemes proposed. The majority of the stratigraphical units is comparable and correlates well however some unsolved stratigraphical problems still exist. To solve these problems additional very detail investigations are needed by applying the new modern methods. The lack of the absolute dates of the Pleistocene sediments is the main problem in both countries.

Abstract (sommario):

In the Post-Exxon Era of sequence stratigraphy, various sequence models for the complex stratigraphic records with their response mechanisms are developed. All the models with strong pertinence are endowed, which lead to misapprehension in the conceptual system. Therefore, the standardization of sequence stratigraphy with the aim to provide consistency in the terminology has become an important motive of modern sequence. During the development of sequence stratigraphy, the identification and distinction between normal and forced regression have laid important foundation for the system description of sequence development. This becomes the first step towards the standardization because of model-independent nature. The introduction of model-independent unconventional system tracts in fluvial sequence models, which are low- and high-accommodation system tracts, which turn out to be another successful attempt of towards the standardization of sequence stratigraphy. The four parts of stratigraphic records, which include the complexity and cyclicity in the stratigraphic accumulation process; the non-gradual change and the non-integrity of the stratigraphic records; the variability represented by the diversity of the sequence models and the nature of standardization including variability, will provide more clues and approaches for further sequence stratigraphy development

Abstract (sommario):

The Anthropocene concept arose within the Earth System science (ESS) community, albeit explicitly as a geological (stratigraphical) time term. Its current analysis by the stratigraphical community, as a potential formal addition to the Geological Time Scale, necessitates comparison of the methodologies and patterns of enquiry of these two communities. One means of comparison is to consider some of the most widely used results of the ESS, the ‘planetary boundaries’ concept of Rockström and colleagues, and the ‘Great Acceleration’ graphs of Steffen and colleagues, in terms of their stratigraphical expression. This expression varies from virtually non-existent (stratospheric ozone depletion) to pronounced and many-faceted (primary energy use), while in some cases stratigraphical proxies may help constrain anthropogenic process (atmospheric aerosol loading). The Anthropocene concepts of the ESS and stratigraphy emerge as complementary, and effective stratigraphic definition should facilitate wider transdisciplinary communication.

Abstract (sommario):

Trilobites are the most diverse of extinct arthropod groups, being known from several thousand genera; many more are discovered each year. They range in age from near the base of the shell-bearing Cambrian to high in the Permian. Because many trilobites evolved quickly, they have been widely employed in stratigraphy; in the Cambrian they are possibly the most important stratigraphical fossils. This has been a mixed blessing because some experts studying the group have tended to place stratigraphical utility foremost in their taxonomic methods. Stratigraphical boundaries have become taxonomic boundaries. This might not matter for stratigraphy, but it does matter for the other kinds of paleobiological studies which have recently become the center of attention. How, for example, can one study extinction, unless the groups extinguished are natural, monophyletic groups? The extinction of an arbitrary phylogenetic segment at a stratigraphic boundary tells us nothing.

Abstract (sommario):

We develop a methodology for systematic inversion of quantitative stratigraphic models. Quantitative stratigraphic modeling predicts stratigraphy using numerical simulations of geologic processes. Stratigraphic inversion methodically searches the parameter space in order to detect models which best represent the observed stratigraphy. Model parameters include sea-level change, tectonic subsidence, sediment input rate, and transport coefficients. We successfully performed a fully automated process based stratigraphic inversion of a geologically complex synthetic model. Several one and two parameter inversions were used to investigate the coupling of process parameters. Source location and transport coefficient below base level indicated significant coupling, while the rest of the parameters showed only minimal coupling. The influence of different observable data on the inversion was also tested. The inversion results using misfit based on sparse, but time dependent sample points proved to be better than the misfit based on the final stratigraphy only, even when sampled densely. We tested several inversion schemes on the topography dataset obtained from the eXperimental EarthScape facility simulation. The clustering of model parameters in most of the inversion experiments showed the likelihood of obtaining a reasonable number of compatible models. We also observed the need for several different diffusion-coefficient parameterizations to emulate different erosional and depositional processes. The excellent result of the piecewise inversion, which used different parameterizations for different time intervals, demonstrate the need for development or incorporation of time-variant parameterizations of the diffusion coefficients. We also present new methods for applying boundary condition on simulation of diffusion processes using the finite-difference method. It is based on the straightforward idea that solutions at the boundaries are smooth. The new scheme achieves high accuracy when the initial conditions are non vanishing at the boundaries, a case which is poorly handled by previous methods. Along with the ease in implementation, the new method does not require any additional computation or memory.

A Bacia de Jacuípe é considerada uma bacia de nova fronteira localizada no Nordeste Brasileiro, na margem passiva leste, e estritamente offshore. Acredita-se que ela tenha um grande potencial para jazidas de hidrocarbonetos. Entretanto, há uma grande carência em estudos integrados que auxiliem no seu entendimento. O presente trabalho visa compreender a história evolutiva da bacia através da interpretação de sequências de segunda e terceira ordens em dados de sísmica de reflexão. A partir da interpretação de 40 perfis sísmicos 2D e do único poço perfurado, que encontra-se na região de plataforma, os autores puderam caracterizar importantes eventos dentro da bacia. Dentro da supersequência rifte foram reconhecidas quatro sequências deposicionais nomeadas Rift 1, Rift 2, Rift 3 e Rift 4, limitadas por três limites de sequência. Os riftes 1 e 2 têm deposições isoladas ao longo da bacia e as falhas sintéticas e antitéticas destas fases começam um processo de conexão. O Rift 3 tem a maior representatividade na bacia e seus depósitos cobrem a maior parte dela. O Rift 4 representa o fim da subsidência mecânica com menores expressões nos falhamentos e experimentou um soerguimento, o qual levou a atual plataforma continental a ficar exposta durante eventos subsequentes. A supersequência Drift foi subdividida em dois estágios drifte. Uma vez que a bacia sofreu um soerguimento ao final do seu rifteamento, o primeiro estágio do drifte tem o preenchimento sedimentar confinado ao talude e ao sopé continental. Enquanto que no segundo estágio do drifte a sedimentação ultrapassa a falha de borda e seus depósitos se sobrepõem à supersequência rifte na plataforma. Um mapa estrutural de falhas foi construído para a porção sul da Bacia de Jacuípe destacando os principais controles do falhamento, a linha de charneira da bacia, principais depocentros, o Alto Externo de Jacuípe e um alto vulcânico. O limite geográfico a sul com a Bacia de Camamu foi definido em uma zona complexa de falhas de transferência e de alívio, caracterizando assim, um limite geológico. Adaptações foram sugeridas para uma nova carta cronoestratigráfica para a porção sul da Bacia de Jacuípe.
ABSTRACT Jacuípe Basin is considered a new frontier basin in the northeastern Brazilian passive margin. It is believed it has a great potential for hydrocarbon plays and leads. However, it lacks in integrated studies for its understanding. The present paper aims to comprehend the evolutionary history of such basin through seismic reflection analysis of second and third orders sequences. With the interpretation of several 2-D seismic profiles and a well drilled on the platform the authors were able to distinguish important events within the basin. Within the rift supersequence it was recognized four sequences named as Rift 1, Rift 2, Rift 3 and Rift 4, limited by three sequence boundaries. Rifts 1 and 2 have scattered depositions and the synthetic and antithetic faults start a linkage process. Rift 3 has a wide spread representation throughout the basin covering most part of it. Rift 4 makes up the termination of mechanical subsidence with minor expression in faulting and has experienced an uplift whose led the currently continental shelf to be exposed most part of subsequent events. Drift supersequence was split in two drifting stages. Inasmuch as basin has undergone an uplift, the first drift stage has sedimentation confined to slope and rise regions. Whereas in the second drift stage sedimentation surpasses the border fault and its successions overlie directly rift supersequence in platform. A structural faulting map was built for southern Jacuípe Basin depicting main faulting controls and trends, basin hinge line, main depocenters, the Jacuípe External High and a volcanic plug. The geographic southern boundary with Camamu Basin was set up at a complex zone of transfer and release faults, making up a geologic limit. Adaptations were suggested for a new chronostratigraphic chart for southern Jacuípe Basin.

Abstract (sommario):

AbstractThis chapter reviews the subsurface stratigraphy of Kuwait targeting geosciences educators. The lithostratigraphy and chronostratigraphy of the reviewed formations (association of rocks whose components are paragenetically related to each other, both vertically and laterally) followed the formal stratigraphic nomenclature in Kuwait. The exposed stratigraphic formations of the Miocene–Pleistocene epochs represented by the Dibdibba, Lower Fars, and Ghar clastic sediments (Kuwait Group) were reviewed in the previous chapter as part of near-surface geology. In this chapter, the description of these formations is based mainly on their subsurface presence. The description of the subsurface stratigraphic formations in Kuwait followed published academic papers and technical reports related to Kuwait’s geology or analog (GCC countries, Iraq and Iran) either from the oil and gas industry or from different research institutions in Kuwait and abroad. It is also true that studies related to groundwater aquifer systems also contribute to our understanding of the subsurface stratigraphy of Kuwait for the shallower formations. The majority of the published data were covered the onshore section of Kuwait. The subsurface stratigraphic nomenclature description is based on thickness, depositional environment, sequence stratigraphy, the nature of the sequence boundaries, biostratigraphy, and age. The sedimentary strata reflect the depositional environment in which the rocks were formed. Understanding the characteristics of the sedimentary rocks will help understand many geologic events in the past, such as sea-level fluctuation, global climatic changes, tectonic processes, geochemical cycles, and more, depending on the research question. The succession of changing lithological sequences is controlled by three main factors; sea-level change (eustatic sea level), sediment supply, and accommodation space controlled by regional and local tectonics influences. Several authors have developed theoretical methods, established conceptual models, and produced several paleofacies maps to interpret Kuwait’s stratigraphic sequence based on the data collected over time intervals from the Late Permian to Quaternary to reconstruct the depositional history of the Arabian Plate in general and of Kuwait to understand the characteristics of oil and gas reservoirs.

Abstract (sommario):

Abstract The Mesozoic stratigraphy of the Middle East is endowed with multiple world-class, economically significant petroleum systems. Since the first discovery of a major oilfield in an anticline structure in 1908 (Masjed-e-Suleyman, Iran), exploration and production in the Middle East has been largely focussed on relatively low-risk, large structural traps. However, across the Arabian Plate, unexplored structural traps at similar scales are becoming scarce. Therefore, in this mature petroleum province, attention must now focus on identifying the presence of subtle stratigraphic traps, especially within the hydrocarbon-rich Mesozoic stratigraphy. In order to locate and evaluate subtle stratigraphic traps, we have applied sequence stratigraphic principles across the Mesozoic strata of the Arabian Plate. This approach provides a regional, robust age-based framework which reduces lithostratigraphic uncertainty across international boundaries and offers predictive capabilities in the identification and extent of stratigraphic plays. Herein, we focus on three intervals of Mesozoic stratigraphy, namely Triassic, Middle-Late Jurassic and middle Cretaceous strata, in which regional sequence stratigraphic based correlations have identified stratigraphic trap potential. Each of these stratigraphic intervals are associated with the following stratigraphic traps:Triassic: Sub-crop traps associated with a base Jurassic regional unconformity and intra-Triassic unconformities. Onlap geometries associated with differential topography on the Arabian Plate.Middle-Late Jurassic: Pure stratigraphic trap geometries associated with basin margin progradation and pinch-out plays either side of the Rimthan Arch related to late Oxfordian/early Kimmeridgian sea-level fall.Middle Cretaceous: Sub-crop potential beneath the regional mid-Turonian unconformity, basin margin progradation and stratigraphic pinch-out geometries associated with onlap onto basin margins. This regional sequence stratigraphic approach highlights the remaining exploration and production opportunities within these hydrocarbon-rich stratigraphic intervals.

Abstract (sommario):

Abstract Delineating seismic stratigraphic features and depositional facies is of importance to successful reservoir mapping and identification in the subsurface. Robust seismic stratigraphy interpretation is confronted with two major challenges. The first one is to maximally automate the process particularly with the increasing size of seismic data and complexity of target stratigraphies, while the second challenge is to efficiently incorporate available structures into stratigraphy model building. Machine learning, particularly convolutional neural network (CNN), has been introduced into assisting seismic stratigraphy interpretation through supervised learning. However, the small amount of available expert labels greatly restricts the performance of such supervised CNN. Moreover, most of the exiting CNN implementations are based on only amplitude, which fails to use necessary structural information such as faults for constraining the machine learning. To resolve both challenges, this paper presents a semi-supervised learning workflow for fault-guided seismic stratigraphy interpretation, which consists of two components. The first component is seismic feature engineering (SFE), which aims at learning the provided seismic and fault data through a unsupervised convolutional autoencoder (CAE), while the second one is stratigraphy model building (SMB), which aims at building an optimal mapping function between the features extracted from the SFE CAE and the target stratigraphic labels provided by an experienced interpreter through a supervised CNN. Both components are connected by embedding the encoder of the SFE CAE into the SMB CNN, which forces the SMB learning based on these features commonly existing in the entire study area instead of those only at the limited training data; correspondingly, the risk of overfitting is greatly eliminated. More innovatively, the fault constraint is introduced by customizing the SMB CNN of two output branches, with one to match the target stratigraphies and the other to reconstruct the input fault, so that the fault continues contributing to the process of SMB learning. The performance of such fault-guided seismic stratigraphy interpretation is validated by an application to a real seismic dataset, and the machine prediction not only matches the manual interpretation accurately but also clearly illustrates the depositional process in the study area.

Abstract (sommario):

Abstract The sequence stratigraphic framework based on the combination of core, lithofacies and logging curve cycles, sometimes hardly reflect the lithology and sedimentary changes between wells, and is inconsistent with seismic data and production performance. Through the integrated research of core, well logging, seismic data and reservoir engineering, this paper proposed an update method. The new method can effectively solve the geological challenges in exploration and development and provide a reliable geological basis for efficient production of the oilfield. This method includes the following 3 steps, (1) identify the sequence stratigraphic boundary integrated the core and lithofacies analysis, and establish the well correlation sequence stratigraphic framework. (2) According to seismic and geological calibration, realize mutual constraint between wells and seismic and robust the sequence stratigraphic framework. (3) The sequence stratigraphic framework is optimized by using production dynamic data, which could grab the sequence stratigraphic framework more consistent with the deposition law. The isochronous sequence stratigraphic framework established by this method in B oilfield of the Middle East truly restores the structural characteristics of the progradational strata of the main production layer in B oilfield, and the sequence boundaries match well between drilling data and seismic data. Under the control of the isochronous sequence stratigraphic configuration, the ambiguous results of the previous division in sublayers according to the lithological isopach were updated, which solved the problems of diachronous oil layer and disordered oil-water relationship in this oilfield. This study also provides an effective isochronous sequence stratigraphic unit for reservoir prediction in exploration and development. Compared with the previous sequence stratigraphy research method in this area, the new method has two major advantages, (1) It complements the shortage of uncertain between wells and increases the accuracy for uncored interval. Furthermore, this method establishes a real isochronous sequence stratigraphic framework. 2) Combined with production dynamic data, the challenge of diachronous sublayers and confusion of oil-water relationship in the research results are avoided.

Abstract (sommario):

The Richardson Trough was a rift basin on the southern margin of an ancestral Iapetus Ocean. It was part of a complex paleogeography that included at least two major rift basins on western Franklinian and northern Cordilleran continental shelves. This paleogeography included the Ogilvie Arch, Porcupine Platform, Blackstone 'supra-basin', Babbage Basin, Husky Lakes Arch, Richardson Trough, Mackenzie Arch, Lac des Bois Platform, and the White Mountains and Campbell uplifts. The Richardson Trough was the failed arm of a triple rift system that formed when an early Paleozoic Iapetus Ocean developed north of the trough. The Richardson Trough displays a classic 'steer's head' profile with two rift fill cycles. The first features late early to middle late Cambrian rifting and late late Cambrian to late Early Ordovician post-rift subsidence; the second, late Early Ordovician to early Silurian rifting and late early Silurian to early Middle Devonian post-rift subsidence. Lower Paleozoic strata exposed in the Richardson Trough range in age from middle Cambrian to early Middle Devonian and are similar to strata in their sister rift, the Misty Creek Embayment. Before this study, the stratigraphic units defined for the Richardson Trough were the Slats Creek Formation and the Road River Formation. Here, the Slats Creek Formation and a new Road River Group are recognized. In order, this group consists of the middle and/or late Cambrian to Early Ordovician Cronin Formation; the early Early Ordovician to latest early Silurian Mount Hare Formation; the early Silurian to late Silurian Tetlit Formation; and the late Silurian to early Middle Devonian Vittrekwa Formation. These Road River Group strata are unconformably overlain by the late Middle to Late Devonian Canol Formation (outcrop) and by the Early Devonian Tatsieta Formation (subsurface).

Abstract (sommario):

Western Davis Strait lies within the Labrador-Baffin Seaway rift system, which began forming in the Early Cretaceous as Greenland separated from North America. At chron C27n (Danian), regional seafloor spreading began, as well as significant magmatism. The opening direction changed from southeast-northwest to more north-south in the Thanetian-Ypresian between chrons C25n and C24n, resulting in significant strike-slip motion through the Davis Strait region until seafloor spreading ended at chron C13, near the Eocene-Oligocene boundary. This tectonism has influenced the stratigraphy preserved in basins within western Davis Strait, including confirmed Cretaceous successions in the Lady Franklin Basin and Cumberland Sound; however, regional overprinting of Paleocene-Eocene volcanic rocks obscures pre-rift basement and possible older strata over much of the region. Three industry wells and several seabed samples of bedrock help constrain the stratigraphic distribution of Cretaceous and Cenozoic strata based on the lithostratigraphy of the well sampled Labrador margin.

Abstract (sommario):

The Geo-mapping for Energy and Minerals (GEM) program (2010-2020) provided a unique opportunity to advance the current level of understanding of the geological history of the Canadian North. In this contribution, based on the Trans-GEM Event Stratigraphy activity, a compilation of Mesozoic-Cenozoic stratigraphic data from across the GEM program regions and beyond is presented, with a focus on biostratigraphic events, using TimeScale Creator, a JAVA package that facilitates the compilation and comparison of large amounts of stratigraphic data while keeping track of changing absolute ages. The '2020 Canada datapack', which incorporates some information re-evaluated and refined from an earlier datapack, includes schemes using dinoflagellate cysts, spores and pollen, foraminifers and conodonts, and a new synthesis of Canadian Arctic Jurassic ammonite and Buchia bivalve biostratigraphy. This datapack will continue to be augmented after completion of the GEM program and will become a major tool in supporting an understanding of Canada's sedimentary basins, their resource potential and management.
