Rare erratic clasts – extraneous rock types occur in the Upper Cretaceous Chalk, including a local basal facies, Cambridge Greensand. The underlying Albian Gault Clay and Hunstanton Red Chalk Formations have also yielded erratics. discovery of these erratics, their description development hypotheses to explain origins significance are reviewed. They became subject scientific interest with inter...

Abstract The Coniacian–Santonian Matulla Formation is one of the important reservoirs in July oilfield, Gulf Suez Basin. However, this formation characterized by uncertainty due to complexity reservoir architecture, various lithologies, lateral facies variations and heterogeneous quality. These challenges, turn, affect effectiveness further exploitation along In work, we conduct an integrated s...

Abstract Due to the growing need for hydrocarbons and limited conventional resources, paying attention unconventional oil gas resources is essential. The upper Jurassic-Lower Cretaceous in western southwestern Iran contains most crucial source rocks of Zagros sedimentary basin. One richest shaly Garau Formation. Owing geochemical geological characteristics, Formation, with Neocomian Coniacian a...

three well - known source rocks of the zagros basin and the persian gulf are mesozoic in age.the jurassic sargelu, albian kazhdumi and neocomian-coniacian garau formations have charged the cretaceous reservoirs of this area. the northwest part of the persian gulf is strongly influenced by two major n-s trending paleohighs (hendijan- bahregansar-regesafid-izeh and kharge- mish) and surrounding p...

In northern Tunisia, the Cretaceous period is described as a spectacular episode of soft-sediment deformations exposed for several kilometers. These gravity-driven are interpreted to be associated with Tethyan passive margin rifting. Slump folds and fault kinematics analysed in order characterize structural style Northern Tunisia basin during period. As result, Early sedimentation reflects syn-...

At the Sidi Bouzid area located in Central Tunisia, Cenomanian-Turonian reservoir rocks are well outcropping, especially in the Jebel el Kébar and Meloussi areas. The present work confirms that these carbonate intervals constitute the lateral equivalent of the Early-Middle Turonian Biréno and Late Turonian-Coniacian Douleb reservoir Members which are included within the pelagic marls of the Tur...

The Late Cretaceous to Cenozoic is known for its multiple inversion events, which affected Central Europe's intracontinental sedimentary basins. Based on a 2D seismic profile network imaging the basin fill without gaps from base Zechstein seafloor, we investigate nature and impact of these events salt structures in Baltic sector North German Basin. These insights improve understanding structure...

To assess the influence of growing salt structures on facies distribution, stratal pattern, and thickness trends, this paper provides tectonostratigraphic framework outstandingly exposed Cotiella minibasins (South-Central Pyrenees, Spain). Based detailed analysis field cross-sections, our results showcase syn-halokinetic upper Coniacian-lower Santonian infill (1.5–3 km thick) records four shall...

The sedimentary strata were sampled in the lesser Himalayas to probe paleoenvironmental changes across Cretaceous-Paleogene (K-Pg) boundary eastern Tethys. study provides an integrated lithologic and bio-sequence stratigraphic analysis, leading paleoecology interpretations. planktic foraminiferal limestone of late Cretaceous is overlain by lateritic sandstones sandy limestones, latter being Pal...
