In this research, the biostratigraphy, microfacies, and depositional environment of carbonate sediments of the Jahrum Formation will be investigated based on microscopic textures and the distribution of benthic foraminifera. The Jahrum Formation was measured from Kuh-e-Hamze Ali in the Chaharmahal Bakhtiari province (Zagros Basin, Iran). The biostratigraphic analysis of this formation has led to the […]
The investigation of lithostratigraphy, biostratigraphy and the microfacies analysis of the Gadvan Formation as an oil reservoir of Lower Cretaceous in the Zagros Basin is crucial. In this study Naser Abad section (Coastal Fars region, SW of Iran), consists of 170 meters thin to medium-bedded limestone with interbeds shale and marly limestone. According to stratigraphic […]
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 […]
