AbstractNo comprehensive study has yet been conducted to determine the chronostratigraphic distribution of palygorskite in the Tertiary sediments of Iran. Thirty sediment samples of different Tertiary epochs were taken, based on the field observations and geological maps. The clay fraction of samples was then investigated by X-ray diffraction (XRD), transmission and scanning electron microscopy (TEM and SEM), and inductively coupled plasma mass spectrometry (ICP-MS). Results showed that sediments of the Miocene and Pliocene had large amounts of palygorskite whereas no trace of this mineral was found in the sediments from the Palaeocene, Eocene and Oligocene. Geochemical analyses revealed that sediments younger than the Oligocene had greater amounts of soluble Mg and H4SiO4and a higher pH than those of the Palaeocene and Eocene. The stability diagram of the smectite-palygorskite system suggests that smectite is unstable and transforms to palygorskite in Neogene sediments. The SEM micrographs showed palygorskite as interwoven fibrous mats, coatings, pore-fillings and pore-bridging material in Neogene sediments. This textural evidence suggests a direct chemical precipitation of palygorskite by dissolution of silicates under the alkaline conditions. The results also suggest that geochemical conditions in the Early Tertiary era, represented by deep-sea conditions in central Iran, were not apparently favourable for palygoskite formation until the Late Oligocene.

Samples of surface sediments originating from different localities in Serbia which contained more than 0.5 % organic matter were investigated in this paper. According to age, these samples were classified into two groups sediments of pretertiary age and sediments of tertiary age. Bulk and specific organic geochemical parameters were determined for their methylene chloride-methanol extracts, aimed at controling the relationship between the age of the sediment and the maturity of its organic substance. In this sense a general direct proportionality was observed. However, a better linear dependence of the bulk parameters was observed in the case of younger, tertiary sediments. That is to say, with samples of pretertiary age the organic matter maturity was approaching a definite limiting value contributing to an inferior linear dependence of their bulk maturation parameters. Nevertheless, the dependence was found to be preserved with specific maturation parameters (e.g., CPI; Fit/n-C18), the changes of which are generally more intensive at higher maturity degrees.

The Penyu Basin is a Tertiary sedimentary basin located offshore Peninsular Malaysia. The basin is assumed to continue westwards beneath the Pahang River delta where as much as 115 m of Quaternary sediments overlie a bedrock of pre-Tertiary granites and metamorphic rocks. No Pliocene or older sediments beneath the delta have been reported. If the Quaternary sediments are considered as part of the Cenozoic Penyu Basin, the basin’s western limit may be delineated at the foothills of the coastal plain where those sediments onlap onto pre-Tertiary rocks. Therefore, any sedimentary rock of Tertiary age that may occur to the west of that limit most probably represents a separate basin.

AbstractSeveral small outliers of Tertiary lavas and sediments rest with strong unconformity on a buried landscape eroded from Torridonian sediments and Tertiary granophyre. Erosion continued during the period of sediment and lava accumulation. Four formations are recognized; these are, in order of increasing age, the Orval Formation (hawaiite and basaltic hawaiite lavas), the Guirdil Formation (icelandite lavas, interbedded conglomerates), the Upper Fionchra Formation (tholeiitic basaltic andesite lavas, hyaloclastite deposits, basal conglomerate) and the Lower Fionchra Formation (alkali and transitional basalt, basaltic hawaiite and hawaiite lava flows, basal conglomerate); each is separated by an erosional interval. Clasts in the conglomerates reveal a history of erosion of a terrain exposing gneisses, Torridonian sediments, igneous rocks derived from the Rhum Tertiary Central Complex (including allivalites), and Tertiary lavas of local origin but also including, in the oldest conglomerates, tholeiitic basalts not now preserved on or near Rhum. Prior to and during lava and sediment accumulation, erosion on Rhum had cut down to a level similar to that of the present day, although not to the extent that high-grade thermally altered rocks, which are a marked feature of the Central Complex, were being eroded in any quantity. A sequence of east–west trending valleys, possibly initiated on the line of the earlier Main Ring Fault, drained the area of the Central Complex which then, as now, must have been high ground. Small lakes occasionally formed in the valleys allowing the accumulation of fine-grained sediment with plant remains, and promoting the formation of hyaloclastite deposits when buried by later flows. No source for any of the lava formations is preserved on Rhum; they are thought to have come from feeders north of Rhum, possibly near Canna, and to have ponded against the hills and valleys near and in the Central Complex.The oldest tholeiitic lavas, not now found in situ, were followed by alkali and transitional flows compositionally similar to the Skye Main Lava Series but characteristically feldsparphyric; the most mafic also contain phenocrysts of magnesian olivine (with included Cr-Al-rich spinels) and aluminous spinel. Both the early alkalic/transitional basalts and the youngest hawaiites and basaltic hawaiites equilibrated at pressures < 9 kb; the tholeiitic basaltic andesites and icelandites equilibrated at relatively shallows depths.Apart from a few N–S to NW–SE-trending basalt dykes, the lava formations represent the youngest Tertiary igneous event on Rhum.

AbstractThe clay mineralogy of a set of Tertiary marine sediments from the Internal Subbetic of the Betic External Zone was examined. Two types of sedimentary environment were distinguished: a platform environment consisting of limestones, marls, organogenic limestones, conglomerates and silexites distributed heterogeneously in time and space; and deep environments, where the sedimentation consisted of marls, marly limestones, marly clays and silexites, with no sedimentary gap. A third group of sediments studied belongs to the Águila Complex, with mineralogical and stratigraphic characteristics very similar to the platform sediments. This third type of sediment is found in the sediments of the Campo de Gibraltar Complex as large, disperse blocks resulting from tectonic activity. A very similar mineral association was observed in all three domains, consisting of smectite, illite, mixed-layer I-S, kaolinite and lesser amounts of palygorskite and chlorite. Materials mainly derive from the erosion of Mesozoic sediments, and sedimentation was controlled by the compressive tectonics of the region.

The Queen Charlotte Basin, which lies on the west coast of Canada, was the location of a petroleum exploration program in the 1960's. Recently published tectonic models indicate that estimates of hydrocarbon potential require re-evaluation, and a renewed exploration interest has been expressed. In 1981, a seismic refraction survey of the upper crust using radio-telemetering sonobuoys and a 27 L air-gun source was carried out. A particular objective of the study was to determine the existence and depth extent of any sedimentary layer, hypothesized on the basis of other studies, beneath or within the Tertiary Masset volcanics in which some of the exploration wells had terminated. Three reversed profiles and one unreversed profile up to 40 km long were recorded. Interpretation of the data made use of the travel-time and amplitude information of the seismic sections by comparison with theoretical sections computed by two-dimensional ray tracing and a new asymptotic ray theory synthetic seismogram algorithm.Consistent with the earlier industry results, sediment thicknesses vary considerably throughout the southern Queen Charlotte Basin. The Tertiary Masset volcanics appear to be pervasive throughout the study area, with thicknesses varying from less than 1 km to greater than 3 km. On three of the four profiles a low-velocity layer, interpreted as Mesozoic sediments or sediments interbedded with volcanics, was found to lie beneath the volcanics. Thicknesses ranged from about 1 km to zero at a pinchout. The lowermost layer of all models is considered to be crustal rocks and is identified with the top of Wrangellia, an allochthonous terrane proposed to underlie the southern Queen Charlotte Basin. Along the profile for which no low-velocity layer sediments were interpreted, the Wrangellia terrane forms a dome rising to within 2 km of the surface. Other recent studies suggest that hydrocarbon sources could be associated with the Mesozoic rocks of Wrangellia and with any sediments underlying the Tertiary lavas, as well as with Tertiary marine sediments above the volcanics. Thus further exploration is warranted.

A combined multichannel seismic reflection and refraction survey was carried out in July 1988 to study the Tertiary sedimentary basin architecture and formation and to define the crustal structure and associated plate interactions in the Queen Charlotte Islands region. Simultaneously with the collection of the multichannel reflection data, refractions and wide-angle reflections from the airgun array shots were recorded on single-channel seismographs distributed on land around Hecate Strait and Queen Charlotte Sound. For this paper a subset of the resulting data set was chosen to study the crustal structure in Queen Charlotte Sound and the nearby subduction zone.Two-dimensional ray tracing and synthetic seismogram modelling produced a velocity structure model in Queen Charlotte Sound. On a margin-parallel line, Moho depth was modelled at 27 km off southern Moresby Island but only 23 km north of Vancouver Island. Excluding the approximately 5 km of the Tertiary sediments, the crust in the latter area is only about 18 km thick, suggesting substantial crustal thinning in Queen Charlotte Sound. Such thinning of the crust supports an extensional mechanism for the origin of the sedimentary basin. Deep crustal layers with velocities of more than 7 km/s were interpreted in the southern portion of Queen Charlotte Sound and beneath the continental margin. They could represent high-velocity material emplaced in the crust from earlier subduction episodes or mafic intrusion associated with the Tertiary volcanics.Seismic velocities of both sediment and upper crust layers are lower in the southern part of Queen Charlotte Sound than in the region near Moresby Island. Well velocity logs indicate a similar velocity variation. Gravity modelling along the survey line parallel to the margin provides additional constraints on the structure. The data require lower densities in the sediment and upper crust of southern Queen Charlotte Sound. The low-velocity, low-density sediments in the south correspond to high-porosity marine sediments found in wells in that region and contrast with lower porosity nonmarine sediments in wells farther north.

Tertiary sediments taken from ten exploration wells and seven outcrop sections in the Bengal Basin together with thirteen oil and condensates and one oil seep and three oil soaked sandstones have been analysed using a variety of organic geochemical techniques. Detailed investigations of the distribution of biological marker compounds indicates that these soils (Surma Basin) are paraffinic waxy oils with a varying amount of C21+ n-alkanes typical of generation from source rocks rich in land plant waxes. The common occurrences of 24-norlupane and oleanane limits the age of the source rocks to Cretaceous or younger and most likely Tertiary. The selective occurrence of bicadinanes in the Surma Basin samples grouped the oils and condensates into two families suggesting the existence of more than one source rock. All the maturity parameters concur that the condensate samples from the Bengal foredeep region are of lower maturity and had been generated at the early stage of oil generation whilst the Surma Basin oils had been generated at around peak maturity of the source rock. The Hararganj oil seep and Sitakund oil-sands are severely biodegraded. The abundances of bicadinanes in Surma Basin oils indicate that they are not restricted to a few South East Asian (Indonesia, Sabah, Brunei) basins only. The occurrence of 24-norlupane has not yet been reported in crude oils and their presence in the Surma Basin oil and condensate samples suggests that they may also occur in Tertiary oils rich in angiosperm markers from other basins. Source characterisation of the various sample suites indicates the existence of at least three organic facies. The Upper Jenam samples with moderate to high organic richness contain abundant plant derived amorphous organic matter sufficient to qualify as a oil regnerating source rock. Maturity measurements of the Upper Jenam formation generally concur that the exposed sequences of this formation are insufficiently mature to have generated and expelled significant quantities of petroleum although the same formation in well sections is around the threshold of oil generation. Despite their immaturity, the source specific triterpane distributions in the Upper Jenam sediments indicates that they correlate closely with the Surma Basin oils. In terms of triterpane distribution the Bhuban sediments show a correlation with condensate samples. Despite their lean organic content, the huge volume of these sediments suggests that the Bhuban formation might have generated minor amounts of early mature condensate.

This PhD Thesis presents the Tertiary kinematic evolution of the South-Central Pyrenees from the integration of magnetostratigraphic, magnetotectonic and thermochronological analyses on its synorogenic sedimentary record. One of the main contributions of this PhD thesis is the continuous absolute dating of the syntectonic conglomerates of La Pobla de Segur, Senterada and Sis. Magnetostratigraphy of these materials establishes their deposition during Middle Eocene-Late Oligocene times (from chron 19r up to chron 9n). Integration of these results with previous magnetostratigraphic works within the Ainsa Basin has allowed the establishment of a new chronostratigraphy for the Eocene-Oligocene materials of the South-Central Pyrenees. The obtained chronostratigraphy has biochronological implications as it substantially changes the traditionally accepted ages of the European reference levels MP14 to MP17. MP14 and MP15 reference levels are proposed to correlate to Lutetian whereas MP16 and MP17 would be Bartonian in age. These results reveal that the correlation between the continental and marine Paleogene record needs further refinement and therefore, that the chronostratigraphic age attributions based on MP reference levels should be taken with caution. The magnetostratigraphic ages have been combined with detrital thermochronology on 13 granitic cobbles enclosed in the syntectonic conglomerates. The detrital apatite fission track ages obtained vary from 63 to 27 Ma. When these ages are combined with the stratigraphic ages, samples define 5 groups with thermochronological ages generally increasing down-section except in the most deeply buried ones due to post-depositional partial annealing. Thermal models reveal three periods of rapid-cooling within the Axial Zone due to movement on large-thrust sheets. A dramatic increase in exhumation rate occurred during the latest Eocene-Early Oligocene related to the onset of movement in the Rialp thrust sheet and the increase in structural relief of the Axial Zone by underthrusting. The magnetostratigraphic and thermochronological ages obtained permit the link between the sedimentation rates in the surrounding basins and the exhumation rates in the hinterland, and reveal that accommodation space exerted the main control on sedimentation rates within the piggy-back basins. Post-depositional annealing of the stratigraphically lowest samples suggests about 2 km of burial by the younger synorogenic materials during progressive burial of the South Pyrenean fold and thrust belt. Thermal models also suggest a rapid exhumation event during the Late Neogene, linked to re-excavation caused by the base level drop during the Ebro River capture to the Mediterranean Sea. Sedimentation of the studied synorogenic materials during Middle Eocene-Oligocene times occurred coeval to the development of thrust salients in the southern Pyrenees. The magnetotectonic study of 36 sites carried out in the Ainsa Oblique Zone reveal clockwise vertical-axis rotations varying from ~80° in the lower Lutetian materials of the Mediano anticline to ~20° in middle Ilerdian materials cropping out at the northern edge of the Añisclo anticline. Sites in the central part of the Montsec and Bóixols thrust sheets don’t record any significant rotation as neither do the syntectonic materials of La Pobla, Sis and Senterada. The age of the main rotation event within the Gavarnie thrust sheet is constrained to Lutetitan to Bartonian times, when all the structures of the Ainsa Oblique Zone were active. This vertical-axis rotation stage obeys to a difference of ~50 km in the amount of displacement on the Gavarnie thrust sheet controlled by the NE-SW pinch out of the Triassic salts at its basal detachment. A second rotation event of ~ 10° took place since Priabonian times, as a result of the differential displacement of about 22 km of the Serres Marginals thrust sheet, respect the Gavarnie one, on top of the upper Eocene-Oligocene evaporites. The synchronicity between thrusting and vertical-axis rotations suggests that the curved fold and thrust belt formed by progressive curvature with divergent thrust transport. The results exposed in this Thesis reveal a strong relationship between the stratigraphic record of the synorogenic materials, thrusting and exhumation in the Axial Zone and the structural evolution of the South Pyrenean thrust system. Tectonic forces controlled the observed patterns of exhumation, the evolution of the synorogenic topography of the piggy-back and foreland basins and the depositional features of the synorogenic sediments.
Aquesta tesi presenta l’evolució cinemàtica dels Pirineus centre-meridionals durant el Terciari a partir de la integració de dades magnetostratigràfiques, termocronològiques I magnetotectòniques del seu registre sinorogènic. La datació magnetostratigràfica dels conglomerats sintectònics de La Pobla de Segur, Senterada i Sis, fixa la seva edat en Eocè mig-Oligocè superior (cron 19r a cron 9n). Aquests resultats permeten establir una nova cronostratigrafia pels materials eocens-oligocens dels Pirineus centre-meridionals de la que deriven implicacions biocronològiques, ja que canvia substancialment les edats acceptades del nivells de referència europeus MP14 a MP17. Les edats magnetostratigràfiques s’han combinat amb termocronologia detrítica de blocs de granit dels conglomerats sintectònics. La termocronologia obtinguda varia de 63 a 27 Ma. Els models tèrmics revelen tres períodes de refredament ràpid relacionats amb el moviment de grans encavalcaments a la Zona Axial, destacant l’ocorregut a l’Eocè superior-Oligocè inferior degut al moviment de l’encavalcament de Rialp i a l’increment de relleu a la Zona Axial per underthrusting. L’annealing post-deposicional de les mostres estratigràficament més baixes suggereix que el cinturó de plecs i encavalcaments pirinenc va estar cobert per 2 km de materials. Els models tèrmics també suggereixen una exhumació ràpida al Miocè superior, relacionada amb la captura de l’Ebre al Mediterrani. Durant la sedimentació dels materials sinorogènics estudiats té lloc la formació de thrust salients als Pirineus meridionals entre els que destaca la Zona Obliqua d’Ainsa. L’estudi magnetotectònic dut a terme en aquesta zona revela rotacions verticals que varien de ~80º a Mediano a ~20º al nord d’Añisclo. L’edat de la rotació principal a la làmina de Gavarnie s’estableix en el Lutecià-Bartonià, quan eren actives totes les estructures de la Zona Obliqua d’Ainsa, i estaria causada per una diferència de 50 km en la quantitat de desplaçament de la làmina de Gavarnie controlada per la distribució de les sals triàsiques al seu desenganxament basal. La sincronia entre encavacalments i rotacions apunta a un model d’arc progressiu amb transport divergent. Aquests resultats revelen una estreta relació entre el registre estratigràfic dels materials sinorogènics, els encavalcaments i l’exhumació a la Zona Axial i l’evolució estructural del sistema d’envacalments dels Pirineus meridionals. Les forces tectòniques van controlar els patrons d’exhumació, l’evolució de la topografia sinorogènica de les conques intramuntanyoses i d’avantpaís i les característiques deposicionals dels sediments sinorogènics.

Tertiary terrestrial sedimentary rocks of the Big Hole basin and Pioneer Mountains of southwestern Montana provide a record of regional extensional tectonism. Detailed observations of stratigraphy and sedimentology at widely scattered outcrops indicate the presence of paleosols, fine-grained debris flows, small alluvial channels, and rare fluvial deposits. U-Pb geochronology of detrital zircons and air-fall tuffs indicates the presence of Oligocene to Middle Miocene sedimentary rocks outcropping at the surface. Though the presence of detrital muscovite in several outcrops indicates derivation from the nearby 2-mica Chief Joseph pluton, a predicted ~75 Ma zircon population is not present: instead, a persistent peak of 70-72 Ma zircons is found throughout the basin, indicating the Chief Joseph pluton may have a younger emplacement age than is currently recognized. Simple physical models developed from Bouguer anomalies indicate the basin deepens and widens toward the south, which agrees with prior work suggesting Eocene initiation of extension in the Big Hole and places it in a class of extensional basins that formed in the early Tertiary. Late Cretaceous, Eocene, and Mesoproterozoic detrital zircon populations, along with consistently immature lithic sands, all indicate sediments were derived from local bedrock sources found around the rim of the modern Big Hole Valley. While these results indicate the Tertiary Big Hole basin resembled the modern basin, some later deformation may have cut off and reversed a paleodrainage flowing out of the southeastern portion of the basin, possibly leading to the modern configuration of the Big Hole River and the deep gorge it carves across the eastern Pioneer Mountains.

[Truncated abstract] Detailed sedimentological, petrographical, geochemical and palynological studies have provided insight into the source rocks and the processes that operated during formation of the Tertiary Yandi channel iron deposit (CID) of the eastern Pilbara, Western Australia. Yandi is the largest and most valuable CID in the world, accounting for more than 2.5% of global iron production in 2003, and is the type-example of CID. The Yandi CID occupies the palaeo-Marillana Creek in the central Hamersley Ranges. It is near-coincident-with the modern Marillana Creek which incised Proterozoic bedrock of the Weeli Wolli Formation (Hamersley Group) and associated dolerite intrusions. Three lithostratigraphic units fill the palaeo-Marillana Creek and comprise the Marillana Formation. The units in stratigraphic order are the: (1) Munjina Member; (2) Barimunya Member, which hosts the majority of the iron resource; and (3) Iowa Eastern Member. Fossil pollen and spores in organic-rich claystones in the Munjina Member indicate that deposition of the Marillana Formation most likely commenced in the Early Oligocene in response to erratic seasonal flows with high energy flood events and intervening quiescent suspension settling of clays. The Marillana Formation consists of twelve facies. These conglomerate and clay facies form three facies associations. The basal facies association is composed of polymictic conglomerate, clay and interbedded CID that represents a lag deposit along the base of the palaeochannel. This facies association characterises the Munjina Member. The second facies association consists of iron-rich conglomerate sheets, bars and subordinate scour-fills and characterises the Barimunya Member. Channel iron deposits of the overlying Iowa Eastern member consist of reworked Barimunya Member iron conglomerates. The upper facies association is polymictic conglomerate with clay that characterises the remainder of the Iowa Eastern Member. Polymictic iron conglomerate in the Munjina and Barimunya Members contains Weeli Wolli Formation and dolerite clasts indicating local derivation. Rare earth element profiles of the other iron conglomerate facies indicate derivation of the Barimunya and Iowa Eastern CID from a different source. These iron conglomerates are characterised by relatively flat LREE profiles. The LREE exhibit an enriched profile approaching the MREE [(average La/Nd)N = 0.7], and the HREE profile shows minor enrichment approaching ytterbium [(average Dy/Yb)N = 0.9]. Comparison of iron conglomerate REE profiles to those of the bedrock indicates that these conglomerates were most probably derived from the Joffre Formation BIF of the Hamersley Group

Ce travail constitue une approche globale des propriétés géotechniques des sédiments d'une partie de la méditerranée occidentale. Quelques aspects généraux mettent en évidence les types de sédiments rencontrés sur les marges continentales et les particularités que présente la pente continentale niçoise (baid des anges), sujet de cette étude. Liés au contexte, les sédiments, pour l'essentiel des boues marneuses, présentent une homogénéité granulométrique et des valeurs de l'indice de plasticité faibles. Les matériaux étudiés dans leur état naturel possèdent des teneurs en eau faibles et des cohésions élevées dans la tranche superficielle des sédiments carottés. Liées à l'environnement et à l'âge des dépôts, trois familles géotechniques ont pu être différenciées. L'évolution verticale des paramètres d'état marque la différence de comportement du sol selon son âge. Les sédiments récents (holocène-pléistocène) en comparaison avec ceux plus anciens du pliocène, possèdent des valeurs de cohésion plus faibles et des teneurs en eau plus élevées. L'évolution horizontale peut se traduire par une différence dans le type de sédimentation. Elle concerne les formations superficielles récentes. En allant de la cote vers le large, on relève des différences dans la valeur du gradient de la cohésion, du poids volumique et de la teneur en eau avec la profondeur d'enfouissement. L'étude des sédiments en conditions dométriques et triaxiales met en évidence une seconde variabilité verticale de cet état du sol. Le sol présente une quasi-surconsolidation dans la partie située de 0 à 1,5 mètres environ, au-dessous de l'interface eau-sédiment. A plus grande profondeur, les sédiments sont normalement consolidés à légèrement surconsolidés. Une méthode d'étude de l'état de consolidation du sédiment à grande profondeur d'enfouissement est également proposée. Fondée sur la valeur que prend le rapport de la cohésion non drainée sur la pression de préconsolidation (cu/#p), elle permet une caractérisation du sol par facies géotechnique et de connaitre l'état de consolidation des formations dans les trois premiers mètres. La sous-consolidation décelée en dessous de 3 mètres, nous contraint à émettre des réserves sur la validité de nos résultats et à formuler des hypothèses. Sans fournir de solution définitive à ce problème, nous relevons qu'un des facteurs à étudier plus en détail, serait la valeur de cu/#p

East Java Province, which is geologically very complex, often occurs natural disasters, especially landslide and land subsidence. The area of East Java is divided into 3 parts, namely the southern part which is the result of volcanic lahar, and also the uplift from the southern sea. Those two kinds of sediment, geologically is quarter and tertiary volcanic deposits age, and limestone. The Middle part, is a cluster of active volcanoes that are quarter old, which provide quarter-aged sediments and these area is rich in geothermal. The Northern part, which is a sediment from the Java Sea and the Madura Strait, with several limestone mountains, is an area rich in hydrocarbons. The area to be studied is the Southern area, namely the quarter sediment from volcanic lava and the lifting of limestone which has the potential to occur landslides and land subsident. The landslide and land subsident symptoms will be analyzed using the geophysical method, to predict the landslide volume and also the dangerous areas with regard to the land subsident.

ABSTRACT Located in the eastern end of Niger delta; the Rio Del Rey (RDR) basin has a unique, complex multi-staged geological features and different types of Structures. This study has aimed to better understand the different structural and stratigraphic setting of the fields within the RDR basin and the way they control the hydrocarbon occurrences. To do that, an integrated 2D and 3D seismic interpretation was done targeting the toe thrust boundary, the upper Cretaceous unconformity and four key horizons of different depth levels in the Tertiary formations. Twelve regional profiles of contrastive orientations that cover the whole basin were interpreted to identify the regional structures; well correlation was done to identify the shallower tertiary settings while additional detailed grids of interpretation at the northeastern and southwestern corners and the seismic facies analysis of the whole RDR study area were used to classify the stratigraphic setting at the deeper regions. The results have revealed that the RDR basin is mainly controlled by thrusting, diapirism and detachment fault structures. The major toe thrust zone is found southern of Ngosso and trends in the northeast-southwestern direction. Gravitational tectonism becomes the primary deformation process shaping the structures as the sediments accumulation increases to the south and consequently, several shale ridges were formed. These ridges and their lateral movement from North to South along with the whole sediments increasing have caused a slope instability of the lower ductile Akata shale formation; what caused the forming of the detachment faults zone in the Northern and middle parts of the RDR basin. The Oongue Turbidites of Eocene were deposited in the northeastern part of the basin in deep water fans by the main sediments supply from the North and the East with various sand thicknesses due to the structural system. The hydrocarbon potential accumulations are found in the mid to upper Tertiary formations and the deeper Upper Cretaceous, but most of the oil and gas fields are located in shallower deltaic reservoirs associated with fault-bounded traps related to shale ridges and diapir structures. Considerable amounts of hydrocarbons were also found within the turbidites sands of Oongue (NE) and Isongo (SE).

Substantial seismic and well data have been gathered and used for the exploration and exploitation of the Salawati Basin since the 1970s. The interpretation of these data and implementation of findings resulted into several discoveries and producing fields associated with the Tertiary petroleum system of Klasafet-Kais, particularly in the Walio Area. The presence of pre-Tertiary petroleum systems remain speculative to date although numerous pre-Tertiary structural and stratigraphic traps can be defined, and hypothetical sourcing can be inferred to origin from shales of the Permo-Triassic Aifam Group and the Late Jurassic – Late Cretaceous Kembelangan Formation. Yet the actual hydrocarbon charging of those traps has not been proven. Surface geochemical surveys were conducted in the Walio Area with the objective to characterize the origin of hydrocarbons of the area and possibly uncover the presence of a pre-Tertiary source. Pre-Tertiary sediments are encountered in three exploration wells of the Walio Area and pre-Tertiary traps were defined by the interpretation of 3D seismic. Surface geochemical surveys were conducted in the Walio Area to map the distribution of oil and gas microseeps and try to determine their source. Whole oil chromatography and isotope & biomarker analysis were also performed on Kais reservoired oil samples to determine source rock lithology, depositional environment, and age. Hydrocarbon analysis of one-meter-deep soil samples revealed the distribution of volatile and liquid hydrocarbon microseeps in the survey area. Total Organic Carbon (TOC) and Rock-Eval Pyrolysis measurement was carried out to outcrop samples of the Klasafet Fm., Kembelangan Fm., Tipuma Fm., and Aifat Fm. The outcrop samples resulted in lean TOC, and produced very low S2 values to which the Tmax cannot be estimated. Hydrocarbon microseeps were found occurring over and off existing fields and pre-Tertiary traps. Both light oil microseeps (35° API) and heavy oil microseeps (14° API) were identified over fresh and biodegraded crude oil Kais reservoirs, respectively in the Walio Area. Microseeps with lighter hydrocarbon compositions (e.g. C5/C17 ratio) may reflect leakage from deeper pre-Tertiary sources.

The basement igneous intrusive rock lithology in the South Sumatra Basin was previously suggested to be a solely granitic rock. It is also a common knowledge that the Miocene Baturaja Formation carbonates are one of the prolific reservoirs. However, after a comprehensive reservoir recharacterization had been conducted in the Suban Field, new insights regarding these two rock types were revealed. The basement lithology consists of a more complex metasediment containing Andesite, Granodiorite, and Gabbro and an Oligocene-age carbonate reservoir was also identified. The reservoir recharacterization was carried out by conducting an integrated analysis to reconstruct the complex reservoir configuration utilizing seismic data, core, cuttings, absolute age dating, and biostratigraphy. Seismic data was utilized as a general framework for reservoir architecture due to the resolution that allowed to describe the reservoir configuration in detail. Core and cuttings were used to identify the reservoir facies, and absolute age dating along with biostratigraphy were used to construct geochronology for each reservoir facies. Finally, well to well correlation was performed to reconstruct complex reservoir configurations. The result of the study indicated that the reservoir age in the field can be divided into two parts, pre-Tertiary (PRT) basement and Tertiary sediments. The PRT of Suban Field comprises several types of crystalline rock that will have different respond to the stresses and the Tertiary section that consists of clastic and several carbonate facies of different ages that vary across the study area. This study offers new insights regarding the basement configuration and the emerging carbonate play. Different igneous rock compositions reflect a complex magmatism process in South Sumatra. Oligocene carbonates that were identified in Suban could open the opportunity to discover a hydrocarbon-bearing Oligocene carbonate play in the South Sumatra Basin.

Juab Valley is a north-south-trending basin in the eastern Basin and Range Province. Juab Valley is bounded on the east by the Wasatch normal fault and the Wasatch Range and San Pitch Mountains, bounded on the west by Long Ridge and the West Hills. Juab Valley is at the southern end of Utah’s Wasatch Front, an area of projected rapid population growth and increased groundwater use. East-west-trending surface-water, groundwater, and water-rights boundaries approximately coincide along the valley’s geographic midline at Levan Ridge, an east-west trending watershed divide that separates the north and south parts of Juab Valley. The basin includes, from north to south, the towns of Mona, Nephi, and Levan, which support local agricultural and light-industrial businesses. Groundwater use is essential to Juab Valley’s economy. The Juab Valley study area consists of surficial unconsolidated basin-fill deposits at lower elevations and various bedrock units surrounding and underlying the basin-fill deposits. Quaternary-Tertiary basin-fill deposits form Juab Valley’s primary aquifer. Tertiary volcanic rocks underlie some of the basinfill deposits and form the central part of Long Ridge on the northwest side of the valley. Paleozoic carbonate rocks that crop out in the Mount Nebo area of the Wasatch Range, which receives the greatest average annual precipitation in the study area, likely accommodate infiltration of snowmelt and subsurface groundwater flow to the basin-fill aquifer. The Jurassic Arapien Formation also crops out in the Wasatch Range and San Pitch Mountains, and dissolution of gypsum and halite in the formation and sediments derived from it increases the sulfate, sodium, and total-dissolved-solids concentrations of surface water and groundwater. We grouped the stratigraphy of the Juab Valley study area into 19 hydrostratigraphic units based on known and interpreted hydraulic properties.
