Integrated organic petrographic and geochemical analyses were made on organic-rich marine carbonate mixed clastic-carbonate rocks of Middle–Late Jurassic Early Cretaceous age from the Shushan Basin, Egypt to evaluate their hydrocarbon potential. Analyses allowed identification depositional settings, paleoclimate, three third order genetic stratigraphic sequences (SQ) with deposits assigned high...

2D multi-channel seismic profiles and a 3D survey were utilised together with potential field available well data to study the late Mesozoic-Cenozoic tectono-stratigraphic evolution of northern Lofoten-Vesterålen margin, offshore Norway. The analysis resulted in an updated structural stratigraphic framework, new better refined elements. Distinct along-margin basin segmentation is evident impose...

Abstract. Extensive black shale deposits formed in the Early Cretaceous South Atlantic, supporting notion that this emerging ocean basin was a globally important site of organic carbon burial. The magnitude burial marine basins is known to be controlled by various tectonic, oceanographic, hydrological, and climatic processes acting on different temporal spatial scales, nature relative importanc...

The early opening of the South Atlantic ocean along the eastern Romanche Fracture Zone, including an initial phase of transform faulting and pull-apart basin formation, followed by the generation of a seafloor spreading center, was investigated during Ocean Drilling Program Leg 159 to the Côte d’Ivoire-Ghana continental margin. Clay minerals in the <0.5-μm fraction of tectonically disturbed sed...

The paper presents original and published data of radioisotope dating volcanic rocks the Magellan Seamounts. These available geological materials allow us to distinguish five major complexes different ages in guyots Seamounts: 1 — Late Jurassic-Early Cretaceous (earliest Cretaceous); 2 Early (Apt-Albian); 3 (Late Cenomanian-Turonian- Campanian); 4 Campanian-Maastrichian); 5 Cenozoic. Each these...

at the boundary between jurassic and cretaceous, because of late kimmerian movements, the sea ragressed from many areas of north and cantral iran, and many continental areas rose, which included a number of differentiated basins. the boundary between jurassic and cretaceous in these parts of iran is usually marked by a big diastem or by red, clastic and evaporitic sediments. the whole or part o...
