Nannofossils are good for biostratigraphy, since they are abundant, planktonic, rapidly evolving and largely cosmopolitan, especially in the Late Cretaceous. For these reasons and due to the lack of any precise paleontological ...

The Asmari Formation has been studied from biostratigraphic and depositional environment point of view in well No. 25, Gachsaran oil field. The thickness of the Asmari Formation in well No. 25 is 632 meters. The study of ...

To study the Bryozoa and the stratigraphy of Permian rocks in the Bazman region an east-west stratigraphic section was studied. The Sarab section, which takes its name from the Sarab River, is located on the southern slope ...

The Talezang Formation is especially extensively outcropped in southwestern Lorestan. It is lying conformably on the Amiran Clastic Formation and its upper boundary contacts the Kashkan Red Siltstone Formation. In the type ...

The Fahliyan Formation of the upper Khami Group(Lower Cretaceous) is composed of carbonate rocks. In order to study facies, depositional environment and sequence stratigraphy of the Fahliyan Formation in the southwest of ...

The Zahedan granitoids, which pertain to an arid to semiarid region, have been studied. Those granite rocks without a cover of Quaternary sediments are exposed directly to dry and warm climate. The characteristic conditions ...

A complete study including field geology, petrography, fluid inclusions, and trace- and rare-earth element geochemistry, and lead and sulfur isotope studies has been carried out on the Baba Gholleh Pb-Zn prospect located ...
