Circum-Tethyan Carbonate Platform Evolution During The Palaeogene: The Prebetic Platform As A Test For Climatically Controlled Facies Shifts, Stefan Höntzsch, Christian Scheibner, Johannes P. Brock, Jochen Kuss
Turkish Journal of Earth Sciences
The distribution of selected shallow-benthic biota at circum-Tethyan carbonate platforms demonstrates an excellent proxy for the impact of latitudinally controlled cooling and variations in the trophic resources during the Palaeogene. In this study, we link and compare the spatial distribution and abundance of larger benthic foraminifera and hermatypic corals of Tethyan carbonate successions with new records from the Prebetic platform in SE Spain. The succession of the Prebetic platform is dominated by larger benthic foraminifera and coralline red algae throughout the Eocene, whereas corals were not recorded until the Late Eocene. Similar biotic trends were reported from 10 selected circum-Tethyan …
Microfacies Correlation Analysis Of The Oligocene-Miocene Asmari Formation, In The Central Part Of The Rag-E-Safid Anticlinal Oil Field, Zagros Basin, South-West Iran, Mahnaz Amirshahkarami
Microfacies Correlation Analysis Of The Oligocene-Miocene Asmari Formation, In The Central Part Of The Rag-E-Safid Anticlinal Oil Field, Zagros Basin, South-West Iran, Mahnaz Amirshahkarami
Turkish Journal of Earth Sciences
The Oligocene-Miocene Asmari Formation was deposited in a carbonate ramp setting at the margin of the Zagros Basin in south-western Iran. The subsurface sedimentary successions of the Asmari Formation have been studied using cores from the Rag-e-Safid oil field, in order to determinate their microfacies and sedimentary palaeoenvironments. Based on texture analysis and faunal assemblages, 10 microfacies types have been recognised and interpreted. They indicate different depositional settings: open marine, oolitic and bioclastic shoal, lagoon, tidal flat and beach. The microfacies have been interpreted as indicative of the inner and middle ramp. In accordance with the temporal and spatial correlation …
