Abstract
Biostratigraphic correlation was conducted on Muthaymimah Formation in the western flank of the Northern Oman Mountains of United Arab Emirates and Atbasi Formation, northwest Turkey. Based on abundance and diversity of foraminiferal assemblages (such as Morozovella spp.) with the lithological characters, the two formations of the Late Paleocene to Early Eocene were deposited under tectonic movements with rapid sea level rise that caused the deposition of mudstone/wackstone facies in open marine environment. Both study areas also share a similar shallow-marine packstone/grainstone facies, rich in benthonic foraminifera (such as Bolivinoides curtus, Neoflabellina jarvisi and Somalina sp., and Nummulites spp.) and skeletal shell remains (molluscs, bryozoa and echinoids), accompanied by thin calcarenite and iron oxides. In both areas, sedimentation occurred during extensive rifting and rapid subsidence, in an environment of seafloor oxidation.
