The Upper Cretaceous Qingshankou Formation black shales,deposited in the late Turonian(LTB shales),are the main source rocks of the Songliao Basin.The origins of organic matter enrichment of the shales is a contentiou...
The Mishrif Formation(Cenomanian-E Turonian)is one of the most important geological formations in the Middle East and Iraq because it contains enormous petroleum accumulations.It is considered to be the first reservoi...
The Sèmè oilfield is located in Benin’s offshore coastal sedimentary basin, near the Benin-Nigeria border, and contains two important oil bearing structures called “Sèmè North” and “Sèmè South”. In this coa...

One of the clocks that record the Earth history is(quasi-) periodic astronomical cycles.These cycles influence the climate that can be ultimately stored in sedimentary rocks.By cracking these(quasi-) periodic sediment...
Although the paleoclimate of the marine Cretaceous has been well studied, the paleoclimate of the non-marine is still not well understood. The Songliao Basin was one of the largest non-marine rift basins during Cretac...

Sequence stratigraphic studies consider relative change in sea level(as regulated by eustasy,local tectonics and sediment supply)as the main builder of the stratigraphic record.Eustasy has generally been considered as...
Late Cretaceous sea inundation of major continents, surprisingly did not affect Indian block except by two major subaerial events of Large Igneous Provinces (LIPs). Marion hotspot induced LIP of Mahajanga Flood Bas...
An attempt has been made to systematically revise the Late Cretaceous (Turonian) bivalves of the Bagh Beds, central India. Altogether, fifteen species have been described here. The two species Nicaniella (N) trigo...
In this study Late Cretaceous stratum in central Iran, Baharestan section in Isfahan area, was evaluated by biozonation and paleobathymetry.?These sediments have 89 meters thick, and strata have been formed of marl an...
