The benthic and planktonic foraminiferal contents of the Bangestan Group (Sarvak, Surgah and Ilam formations) in the Sepid Kuh anticline in the Lorestan Zone, W Iran, were studied. Bangestan Group consists of limestone, argillaceous limestone, dolomitic limestone and marl with thickness of 5400 m.

The Burdigalian carbonate of the Central Iran contains very well-preserved specimens of Kuphus polythalamius. The tube of Kuphus polythalamius is a calcareous secretion that enables Pelecypoda to live in the mud of shallow seas. This research focusses on the Paleontology and taphonomy of the Kuphus polythalamius of the Member F (Qom Formation) in the southeast […]
In this study, a foraminiferal biozonation scheme for the Late Cenomanian – Coniacian deposits for the Lorestan basin, is proposed. Five successive biozones are recognized within the Sarvak, Surgah and Ilam formations, which in stratigraphic arrangement are Nezzazata – Alveolinids Assemblage Zone (Late Cenomanian- Early Turonian), Helvetoglobotruncana helvetica Total Rang Zone (Early- Middle Turonian), Marginotruncana […]
