Introducing the ostracods in marls units 1 and 3 (K1 and K3) of Tarbur Formation in Chehel Cheshmeh Kherameh Mountain (Southeast of Shiraz)

Abstract

Abstract
As ostracods are excellent index in determining the paleoenvironment, age and paleoecology of sediments, the ostracods in marls units 1 and 3 of Tarbur Formation have been studied. Tarbur Formation with 712 m thickness is divided into 6 units. In this study, 60 samples of marls units 1 and 3 have been washed, and studied and totally 21 species identified. The ostracods indicate a Maestrichtian age and warm, oxygen-rich and shallow depositional environment for the studied units.
