Studies described in this report have been realized in order to clarify of geological events series which took place in Lebanon between Upper Jurassic and Lower Cretaceous. Classically attribute to Upper Jurassic (Kimmeridgian – Thitonian) “Bikfaya and Salima formations” top limestone are covered by azoicals sandstones : “ les Grès de base”. Top sandstones are full of undated ambriferous deposits. Sedimentary and micropaleontological studies of sample collected upon all over Lebanon show various diachronies for limestone-sandstone contacts. For ancients authors, this contact means Jurassic-Cretaceous boundary. For us, it emphasize an ancient and complex geological history of a composite land, altered by Middle East Plio-Quaternary tectonic activity. We propound Lebanon’s west border (costal plain and Mont Liban) evolutes during Jurassic as subsident lozenge basin border connected with Syrian Palmyrides. Then, consequently to reversal tectonic North part of the Mont Liban has been gradually uplifted, eroded and karstifed. In the same time, Chouf and is border receive continues limestone sedimentation probably until Late Neocomian. Vertical and horizontal variability of the limestone sedimentation resulted from differentials moves of a keyboard like substratum. Limestone-sandstone contact have been studying in Anti-Liban mount and show totally different geological history that the other part of Lebanon. Then, Anti-Liban mount sent continentals sand flows to Chouf depressions. Those depressions had regular tectonically and volcanic activity during their filling up by sand. Sandstone deposit is totally diachronic in Mont Liban, with a North progradation. Quartz deposit started in costal limestone environment and finished in continental’s. At the end of tectonically activity Lebanon is covered by clayey and ambriferous sandstones deposits

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

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

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

Isotopic ([delta]18O and [delta]13C) and elementary geochemical data as well as macro and microfossil associations, show a chemical change in the water of the lagoonal platform in the eastern Paris Basin, during the Late Oxfordian/Early Kimmeridgian interval (Upper Jurassic, ~156 Ma). Gradually, the shallow tropical environments dominated by biomineralization of carbonates became confined, dysoxic and colder. Correlations between depositional environments with similar facies in the Southern and in the Eastern Paris Basin helped to improve the biostratigraphic frameworks. Comparisons between the sequential frames deduced from the palaeoenvironmental evolution of Berry and Lorraine places the maximum regression of a 3rd order cycle at the Planula and Platynota ammonite zones boundary. Recently, the Flodigarry Shale Member, a shaly succession located on the Isle of Skye (Scotland), has been proposed as a possible GSSP (Global Stratotype Section and Point) to define the Oxfordian/Kimmeridgian boundary. The section was studied in order to compare this subboreal series to submediterranean deposits (Paris Basin) by means of other markers such as organic molecular contents. It revealed very well preserved biomolecules, among the oldest identified in the world. This thesis provides new palaeontological, geochemical and stratigraphic data in both Jurassic palaeobiogeographic realms. Well documented sections of the Eastern Paris Basin are now available for this interval. Such local observations, integrated in a multidisciplinary approach, should strengthen the correlations across these realms and precise the global components of the crisis of the carbonate production near the O/K boundary

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

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

The Atlas basins of Morocco expose the history of two closely related Jurassic intracontinental rift basins corresponding to the Middle and the High Atlas. These sedimentary basins represent one of the best examples of extensive/compressive tectonic regime on the west coast of Africa and although they have a quite similar sedimentary history they have undergone different thermal evolution. This work is to explore the effect of these differences in terms of diagenesis and fluid flow. Several tectonic and sedimentary studies on the Atlas basins exist though very few of them focuse on the characterization of diagenetic processes. This study is based on an integrated petrographic and geochemical approach to further our basic understanding on petrogenesis and diagenetic fluid compositions. It focuses on diagenetic processes and fluid compositions related to different diagenetic stages in three locations representing: 1) the depocentre (loc. Aït Moussa); 2) a major fault zone (loc. Tunnel de la Légion); and 3) the carbonate platform (loc. Aït Athmane). Diagenetic stages are divided into three stages (eodiagenesis, mesodiagenesis and telodiagenesis) using stratiform and tectonic stylolites as markers. Relative chronology of fracture generations and stylolites based on cross-cutting relationships enables to assign fracture generations to each diagenetic stages. Detailed paragenetic and geochemical analysis on fracture and pore-filling cements help to establish the paragenetic sequences and to illustrate the relationship between different diagenetic mineral phases in a time/space-resolved petrogenetogram. Geochemical analyses have been done in ordre to investigate the nature and the origin of diagenetic fluids circulating in the study areas from the rifting period until the formation of the Atlas Mountains. Various diagenetic processes including cementation, dissolution, compaction, recrystallization, replacement, dolomitisation, and dedolomitisation are observed at the different locations. At Aït Athmane, eodiagenetic stage is essentially controlled by sea level fluctuations while telodiagenetic stage was tectonically controlled by the circulation of ascending fluids through major faults enriched in lead and hydrocarbon. The thermal maturity model based on vitrinite reflectance (Ro 0.85 and 1.34 %) analysis on samples from Aït Moussa indicates a maximum burial depth around 3.7 km, reached during Upper Cretaceous to Early Paleogene, with a maximum diagenetic temperature of approximatly 120ºC. Tmax values calculated from argillaceous limestones at Tunnel de la Légion range from 470ºC to 500ºC indicating overmature sedimentary successions in the area. Both Atlas rift basins contain a rift-type and a platform-type petroleum system, a situation that also applies to the numerous Atlantic-type, margin-related rift basins that formed during Triassic – Jurassic rifting along western Africa. The petroleum system of the Atlas basins is fairly well documented, but certain aspects as hydrocarbon generation and migration stages are poorly understood. At the locality of Aït Moussa, hydrocarbon generation stage is recorded as fluorescent inclusions in dolomite crystals (dolomite-2 and -3) and starts in the Late Jurassic - Early Cretaceous (approx. 150 Ma). Hydrocarbon fluids remained normally pressured until the opening of late diagenetic fractures during Late Eocene tectonic compression. At the locality of Tunnel de la Légion, hydrocarbon generation stage begins with the opening of conjugate fractures during Late Cretaceous – Early Paleocene and continue until the begining of tectonic compression (Late Eocene). At the locality of Aït Athmane, hydrocarbon generation stage is synchronous to the opening of the second generation of fractures and continues after the begining of tectonic compression. The GC and GC-MS chromatograms of samples taken from the three location shows a very similar n-alkanes pattern with a maximum at n-C17 and n-C19. Biomarker analyses revealed that the origin of the organic matter in the localities of Aït Moussa and Tunnel de la Légion is marine (kerogene type II and I) and the small differences are related to thermal maturation and to migration. An exploration strategy should consider the begining of hydrocarbon migration stages and associated fractures relative to the rock reservoir formation.
