They serve as westernmost reference for adjacent prolific reservoirs and source-rock bearing intrashelf basins. Several hierarchical sequences (second to fourth order) have been recognized in outcrops sections (600 km long south of Riyadh) and correlated with gamma-ray logs of subsurface wells (550 km long from Riyadh to Rimthan Arch). The Jurassic platform evolved from very-flat continental-to-nearshore mixed carbonate-siliciclastic platform (Marrat-Dhruma; Toarcian to Middle Callovian) to differentiated ramp with deep intrashelf basins (Tuwaiq-Hanifa; Callovian to Early Kimmeridgian) to a lowstand followed by flat aggraded platform (Jubaila-Arab-D; Kimmeridgian). Tectonic related siliciclastic influx took place in arid condition during the Kimmeridgian (Jubaila Fm.). The Jurassic platform ends with the mixed carbonate-evaporite systems of the Arab Fm. A first second-order tectono-eustatic cycle (Marrat to Tuwaiq) is bounded at the base and top by regional unconformities. It has a stationary depocenter, and show long-term coastal onlap and marine transgression that reached its maximum extent during the upper Tuwaiq (Middle Callovian). The Hanifa Fm. consists of four 3rd-order sequences aggraded flat-toped platform (outcrops to Khurais) marked at the base by argillaceous limestone and top by pure high-energy carbonates with localized reef buildups. The Jubaila Arab-D is two 3rd-order sequences begin with low-stand deposits followed by long-term transgression. These formed flat successions with lateral thickness variations controlled by differential subsidence increased in the Arabian Basin. The transgression is marked by storm-influenced inner-platform with sandstone quartz, grainstones and restricted lime-mudstone. The Maximum marine transgression is placed in the Arab-D with reef buildups in the westernmost inner-platform. During highstand, the reefs are gently prograding out into Rimthan Arch leaving behind restricted lagoon and sabkhah/salina anhydrite

The abundance of glauconite and belemnites combined with ichnology and biostratigraphic assemblages associated with marine environments, indicate that deposition of all the sandstone facies occurred within an outer shelfal - deep marine environment. Reservoir quality was best developed in the dominantly medium grained, moderate - well sorted sandstones, (facies 7), which were deposited as detached, basin floor submarine fan sands or interbedded turbidites. In contrast, reservoir quality was relatively poorly developed in the remaining facies which were deposited as slope fans, slumps, or distal turbidite deposits.The abundance of quartz and presence of banded iron, jasper, and potassic feldspar grains support the provenance for the basinal sandstone facies being the Precambrian alkyl granites and banded iron formation of.the Pilbara Shield and Hammersley Ranges. These Precambrian igneous rocks and metasediments mark the eastern boundary of the Barrow Sub-basin study area. To predict the distribution of sedimentary facies in the Upper Jurassic synrift sediments of the eastern Barrow Sub-basin, the interplay between the major controlling depositional processes, namely tectonics, sediment supply and eustasy must be understood. Subdivision of the synrift sedimentary section on the basis of lithostratigraphy can be misleading and does not adequately resolve the facies relationships observed in the well intersection. The results of this research form the basis for a regional sequence analysis and seismic stratigraphic study.

The objectives of this thesis are (1) to characterize the factors controlling the large-scale development of intracratonic carbonate platforms and (2) to link early diagenesis of discontinuities with palaeoenvironments and sequence stratigraphy models. The evolution of the western France carbonate platform is reconstructed from the Aalenian to the Oxfordian (17 million years). The basement topography controls bathymetries until the mid-Bathonian. Regional tectonics promotes or prevents locally carbonate production. General stages of carbonate platform growth and demise in western Tethyan basins are controlled by 9 million years’ climatic variations. Carbonate production is low during humid intervals and high during dry intervals disturbed by short periods of intensive rainfall. High resolution isotopic analyses(δ18O and δ13C) were performed on various early cements located below discontinuities to reconstruct the palaeoenvironmental conditions leading to their formation. Dogtooth cements, micritic meniscus and envelopes precipitated in low-magnesium calcite directly in seawater. A new model, linking architecture, facies, sequence stratigraphy and early diagenesis is proposed for an oolitic platform wedge. On the inner platform, discontinuities change laterally from subaerial surfaces to marine hardgrounds, whose erosion leads to the deposit of an intraclasts level on the platform wedge. Early cements are only located under discontinuities and are absent in the platform wedge because of a continuous sedimentation rate

In the last decade, important oil discoveries have been reported offshore Lebanon in the eastern Mediterranean waters. Numerous offshore geological studies (Levant Basin) with seismic acquisitions (2D and 3D) have revealed hydrocarbon reservoirs of Miocene age and suggest promising exploration prospects. In addition, petroleum system modeling has been carried out on the scale of the entire region and shows that the Triassic-Jurassic formations are potential source rocks that have reached thermal maturity due to strong tectonic control at certain periods. While these formations have been extensively studied in the Middle East (Syria, Jordan, ...) and have allowed highlighting their petroleum potential, the Lebanese onshore area has been little studied. The complete stratigraphic approach and the analysis of the Lebanese onshore sedimentary basin are still lacking in some aspects, not allowing to define perfectly the role of tectonics on the geometry, the nature, and the timing of sedimentary and diagenetic events.The objective of this thesis is to characterize the geometry of the sedimentary deposits of the onshore basin and to explain the tectonic control on its' stratigraphic record. A set of geological data from the literature on the region (depth settings, stratigraphy, etc.) is synthesized in a 3D geological modeler (SKUA-GoCad®). From these geo-modeled data, an interpretative approach allows to visualize: i) the sedimentary deposits of the Lebanese basin; ii) the major tectonic structures controlling this basin; iii) the major erosion surfaces and iv) the potential oil traps as elements of petroleum systems. This approach allows then to generate tectonic subsidence curves of the sedimentary basin in the Lebanese onshore and part of the offshore (using PetroMod®) and to interpret them. The results describe the relationships between sedimentation and tectonic evolution at the regional scale of Lebanon, define the major faults that controlled the sedimentary record, identify some key phases during the geodynamic evolution and thus trace the tectonic history of the country.From a regional to a more local scale, this thesis focuses on a fault set having a controlling role on the sedimentary record, by studying one of them in the Nahr Ibrahim area. This work focuses on the early Mesozoic (Jurassic) period present in the Lebanese territory and a little-studied structural system that affects it: the NE-SW Mesozoic normal fault system reactivated during the structuring of the Levantine Fault System. In order to characterize the tectonic control of these faults on sedimentation (geometry and diagenesis), a field study was carried out in the Nahr Ibrahim region, with a sedimentary, geochemical and diagenetic approach. Thus, three stratigraphic sections in the Kesrouane Formation (Jurassic) are presented. A study of the facies and of the diagenesis allows to identify the variations of environments, then the main diagenetic phases that this Jurassic formation underwent. Using a chemo-stratigraphic approach (strontium isotopes in particular), a calibration by absolute ages is proposed which allows the correlation of the stratigraphic sections and highlights a vertical rejection of the regional Nahr Ibrahim fault of about 800 m. The results highlight the important role of these faults in the control of Jurassic sedimentation, the geometric structuring of the Mesozoic formations, and their potential role in diagenesis. Also, this local approach has allowed us to revisit and improve the regional 3D model by considering the major role of these reactivated NE-SW faults (800m fault vertical offset) affecting the stratigraphy

This transdisciplinary study including sedimentology, sequence stratigraphy, chemostratigraphy, and organic and inorganic geochemistry examines the Middle-Upper Jurassic carbonates series located in the southwestern Gissar range. These carbonates, also known as the Kugitang series, represent the most complete outcrop of the northern margin of the Amu-Darya Basin, a gas-producing province of Central Asia. Carbonate production begins in the late Early Callovian during a regional slowing of the tectonic subsidence, coeval with a climate warming. A major change in the carbonate production and platform configuration is recorded at the end of the Callovian: (i) a carbonate ramp with a well-contrasted proximal-distal gradient develops during the Lower to Middle or Upper Callovian. It is overlain by (ii) a vast low energy lagoon dominated by peritidal facies, probably protected by large reefs, during the Lower and Middle Oxfordian. The stratigraphic surface separating the two depositional sequences is associated with a hiatus (Upper Callovian-Lower Oxfordian) and interpreted as a regional exposure surface recording a sea-level drop caused by tectonics and/or climate. During the Middle Oxfordian, one or several intrashelf basins develop southwestwards of the studied carbonate platform. Laminated and nodular carbonates rich in organic matter predominate in these basins. They are interpreted to have formed through the mineralization of microbial mats colonizing the stratified, slightly hypersaline, anoxic to dysoxic basin floor. Large scale reefs may have favored the isolation of these basins. These deposits record the initiation of the tectonic isolation of the Amu Darya Basin, which culminates with the progradation of a large-scale sabkha and the deposition of a thick anhydrite and salt series. The comparison of stratigraphic series highlights common events in several basins of the northern Tethyan margin, but also with the Arabian Plate: initiation of the carbonate platform, carbon isotope excursions, age and depositional conditions of organic-matter rich rocks, etc. The petrography and geochemistry of carbonates reveal a complex diagenetic history. Some facies are strongly controlled by the sedimentary fabric. The diagenetic succession is tentatively linked with the stratigraphy and the subsidence history. Following deposition, the Kugitang series was buried at more than 2 km. Some cements are interpreted to have formed through the circulation of hot fluids in the rocks during the mesogenesis and possibly due to thermochemical sulfate reduction, especially in the Callovian Sequence. Finally, the high-resolution stratigraphy established in this study is used to help improving the prediction of carbonate reservoirs in the subsurface Amu Darya Basin
Geesaman, Patrick J. "Structural observations and stratigraphic variability in Jurassic strata, Upheaval Dome, Canyonlands National Park, Utah, USA". Thesis, Colorado School of Mines, 2014. http://pqdtopen.proquest.com/#viewpdf?dispub=1549082.
Upheaval Dome is a structurally deformed topographic depression located in Canyonlands National Park, southeast Utah. Multiple hypotheses for its origin have been proposed by various scientists over many years of research. The two remaining viable hypotheses are at opposite ends of the geologic spectrum, one proposing long-term deformation of the structure, while the other proposes a catastrophic meteorite impact. (1) The seminal paper by Jackson et al. (1998) suggests that Upheaval Dome was created due to the growth and subsequent pinch-off of a salt diapir sourced from the Pennsylvanian Paradox Formation. Their conclusions were based on various growth geometries in Jurassic age strata. (2) Perhaps the most influential paper proposing a meteorite impact at Upheaval Dome is by Buchner and Kenkmann (2008), titled "Upheaval Dome, Utah, USA: Impact origin confirmed". In this paper only two grains of shocked quartz are identified, out of 120 standard thin sections. Based on these thin sections comprising medium-coarse sand grains, only ~0.00043% of grains displayed evidence of high-pressure deformation. For shocked quartz to confirm a meteorite impact there must be abundant shocked grains (2-5%), and ~0.00043% cannot be considered abundant (French and Koeberl, 2010).
Prior to this study there has been no attempt made to combine an in depth stratigraphic investigation of exposed, accessible formations with structural and lithologic observations in the Upheaval Dome area. Analysis of stratigraphic field data for Triassic to Jurassic-aged strata reveals: (1) stratigraphic thicknesses from measured sections range from 7 meters to 224 meters in the Kayenta Formation, and projected thicknesses in cross sections can exceed 400 meters; (2) distinct changes in facies distributions in relation to mapped structural features; (3) localized angular discordances, such as angular unconformities and onlaps, at the contact between formations or within individual formations.
Analysis of structural features at Upheaval Dome reveals: (1) synclinal axes and associated depositional centers shift throughout the Jurassic; (2) stratigraphic thicknesses across normal faults from hanging to footwall blocks are unequal on the scale of meters to tens of meters; (3) thrust faults verge dominantly to the southeast regardless of the side of the dome they are located on; (4) blocks of Triassic Chinle Formation encased in the younger Jurassic Wingate Sandstone adjacent to dog tongues suggests the involvement of a brief period of allochthonous salt break out after the deposition of the Chinle. Petrographic analysis was inconclusive, as there were no shocked grains, nor any clasts of the Paradox Formation present in younger formations.
The research presented in this study strongly indicates that long-term deformation occurred at Upheaval Dome during the Early Jurassic and possibly in older less well exposed units. Evidence supporting long-term deformation includes growth strata, changes in facies distributions, shifting formation depocenters, angular discordances, and growth faults. Sparse indicators of catastrophic are also present in the form of sparse shocked quartz grains and poorly developed shatter cones. To accommodate these juxtaposing deformational regimes an evolution of Upheaval Dome is presented here that relies on an early meteorite impact to initiate active diapirism leading eventually to a passively growing salt diapir. This explanation would account for the petrographic evidence supporting meteorite impact, as well as the growth geometries in the Triassic-Jurassic aged strata surrounding Upheaval Dome.
Upheaval Dome has historically been one of the most controversial geologic features in the United States. It is important for geologists to understand the genesis for this structure as it is an extremely well exposed field example of a meteorite impact, pinched-off salt diapir, or a combination of the two, and can help further understand similar structures found around the world at the Earth's surface, or in the subsurface.

Ahmed, Sirwan Hama. "Tectonostratigraphic evolution of the northeastern Arabian Plate in Kurdistan since the Jurassic". Paris 6, 2013. http://www.theses.fr/2013PA066625.
The studied area is located in Northern Iraq in the Kurdistan Region, which approximately corresponds to the North-Western part of the Zagros belt. The Zagros belt is an active fold and thrust belt approximately 1800 km long, mainly resulting from the deformation of the sedimentary sequence of the Arabian margin and shelf during the Cenozoic Arabian-Eurasia collision. This study concentrates on the tectono-stratigraphy evolution of Kurdistan from Jurassic up to present. However we mainly investigated the evolution of the pre-collision period, focusing on the relationship between tectonics and sedimentation. In this study we developed (1) a biostratigraphic approach using nannofossil analysis, (2) a fault tectonic analysis, and (3) a stratigraphic study of the Jurassic to Neogene sequences (more particularly the Cretaceous series). The Zagros fold belt in Kurdistan exhibits many lateral and vertical environmental and facies changes, especially during the Cretaceous times. During the Jurassic period the Kurdistan is occupied by the restricted Gotnia Basin. This basin disappeared and the Kurdistan area changed to open marine of a southwest Kermanshah Basin during the Cretaceous. During the Berriasian to Barremian the Kurdistan was covered by the carbonates of the Balambo and Sarmord formations. In the east and southeast the neritic Sarmord Formation gradationally and laterally passes to the basinal facies of the Balambo Formation. In the Aptian to Cenomanian period shallow massive reefal limestone of the Qamchuqa Formation deposited. The normal faulting that initiates during the Aptian is associated with an abrupt lateral change of the reefal Qamchuqa Formation to the Aptian-Cenomanian part of the Balambo Formation. During the Cenomanian-Early Turonian periods the graben formed in the Dokan Lake in eastern Kurdistan, where developed a deeper restricted environment (Dokan and Gulneri formations) surrounded by a shallow marine platform. During the Turonian the marine pelagic micritic cherty limestones of Kometan Formation covered northeast of Kurdistan, whereas in the Safeen, Shakrok and Harir anticlines the formation was totally, or partially, weathered during the Coniacian-Early Campanian period. The deposition during the Late Cretaceous is very heterogeneous with a gap in the Coniacian-Santonian times probably related to a non-deposition. Associated with extensive tectonics a basin developed during the Campanian with the deposition of shales, marls and marly limestones of the Shiranish Formation. The first appearance is the Kurdistan of the flysch facies of the Tanjero Formation was precisely dated of the Upper Campanian in northeastern Kurdistan. The Tanjero Formation conformably overlaying the Shiranish Formation and was deposited in the foredeep basin associated with the obduction of Tethyan ophiolites onto the Arabian Platform. The Early to Late Campanian period is a time of non-deposition in Central Kurdistan (Safeen, Shakrok and Harir anticlines). During the Late Campanian the Bekhme carbonate platform in the north disappeared when the marly limestones of the Shiranish Formation transgressed over the Bekmeh Platform. In the Aqra area the Maastrichtian Tanjero Formation laterally changed to the thick reefal sequence of the Aqra Formation that unconformably overlies by the Late Paleocene-Early Eocene lagoonal carbonate of the Khurmala Formation. The Campanian sedimentation is mainly controlled by NE- oriented normal faults forming Grabens in Dokan, Spilk and Soran areas. During the Maastrichtian in the extreme northeastern Kurdistan the NE-SW and NNW-SSE normal faults developed in the foredeep basin and originated horsts and grabens. Clastic sediments accumulated in the grabens and the reefal carbonate developed on the horsts. These bars are several tens of meters thick and commonly several kilometres long. The study of the brittle deformations in these Middle-Upper Maastrichtian carbonate bodies showed that the strike-slip faults associated with the extension, formed by permutation of the orientation of σ1 and σ2 axes. However most of the paleotensors reconstructed (compressional and strike-slip regimes) in the Kurdish Zagros from analysis of fault populations are associated with the Late Cenozoic Zagros orogeny, which results from the collision between Arabia and Eurasia. The Neogene stress field related to this major event is characterized by alternating compression with the principal stress axes σ1 oriented NE-SW to ENE -WSW with a main peak oriented NE-SW
