Diagenesis of Upper Cretaceous Rudist Bivalves, Abu Roash Area, Egypt: A Petrographic Study
The Upper Cretaceous was a period when reefs and reef mounds were abundant in many parts of the world (JAMES, 1983). One of the most remarkable features of the Cretaceous carbonate platforms in tropical and subtropical environments of the Tethyan realm, was the development of facies complexes dominated by rudists, with or without associated corals (MASSE & PHILIP, 1981; ROSS & SKELTON, 1993; GI...
متن کاملSystematic of Albian - Cenomanian Gastropods and Bivalves from the Kazhdumi Formation, Zagros Basin
The Albian- Cenomanian (Kazhdumi Formation) sediments from northeast of Shiraz, Zagros Basin, represents a carbonate sedimentary succession and contain diverse gastropods and bivalves. Detailed studies on 80 samples of invertebrate macrofauna on two stratigraphic sections led to recognized 2 species and 5 genera of gastropods and 7 species and 13 genera of bivalves assemblages. The abscence of ...
متن کاملPlanktic Foraminiferal Species Turnover across Deep-sea Aptian/ Albian Boundary Sections
A major planktic foraminiferal species turnover accompanied by a dramatic reduction in shell size, a fundamental change in shell architecture, and a precipitous drop in the abundance of planktic relative to benthic species occurs across the Aptian/Albian boundary interval (AABI) at globally distributed deep-sea sections. Extinction of the large and distinctive planktic foraminifer Paraticinella...
متن کاملHistorical distribution patterns of trigonioidids (non-marine Cretaceous bivalves) in Asia and their palaeogeographic significance.
The non-marine trigonioidid bivalves show five phases of radiation in the Cretaceous of Pal-Asia: pre-Aptian (?Valanginian/Hauterivian-Barremian), Aptian, Albian, Cenomanian and Turonian-Maastrichtian. Their distribution patterns show two distinct palaeo-river systems feeding trigonioidids. Before the Cenomanian, the river system occupied the southwestern-southern-southeastern Pal-Asian contine...
متن کاملPaleoclimate record in the Nubian Sandstone Aquifer, Sinai Peninsula, Egypt
a r t i c l e i n f o 14 C adjusted model age Paleowesterlies Paleomonsoon Sixteen groundwater samples collected from production wells tapping Lower Cretaceous Nubian Sandstone and fractured basement aquifers in Sinai were analyzed for their stable isotopic compositions, dissolved noble gas concentrations (recharge temperatures), tritium activities, and 14 C abundances. Results define two group...
