Biostratigraphy and foraminiferal Assemblages of the West Siberian Albian

Overview of Eocene Planktonic Foraminiferal Taxonomy, Paleoecology, Phylogeny, and Biostratigraphy

This monograph has been compiled by members of the Paleogene Planktonic Foraminifera Working Group (hereafter referred to as the Working Group) of the International Subcommission on Paleogene Stratigraphy, International Union of Geological Sciences. It is the second such work in a projected series of three, the first being the Atlas of Paleocene Planktonic Foraminifera published by Smithsonian ...

Systematics and Biostratigraphy of Foraminifera in Albian to Lower Cenomanian Deposits at Kerch Section (Southwest Qayen)

In this research systematics and biostratigraphy of the Cretaceous deposits foraminifera in Kerch section, southwestern Qayen, in the eastern margin of the Lut Block, were studied in detail. This section with 260 meters thickness, mainly formed by gray to cream color marl and shale, marly limestone and limestone laid on a light-colored limestone bed at the base. Seventeen genera and twenty two ...

Abyssal hills: Influence of topography on benthic foraminiferal assemblages

Benthic foraminiferal and calcareous algal biostratigraphy of the Fahliyan Formation in oil well no. X1, Dorood Oilfield, Persian Gulf

The Dorood oilfield is located offshore in the northern part of the Persian Gulf. It partly underlies the Kharg Island. The Neocomian Fahliyan Formation represents the high-quality reservoir in the oilfield. It includes five carbonate members: The Manifa, Middle and Upper Yamama, Khami and Lower Ratawi. The Fahliyan Formation in the studied well attains a thickness of 378.1 m and mainly consist...

Planktic 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...
