Abstract

In this research, totally 610.4 meters of the Asmari Formation are studied in two stratigraphic sections on Bavan Mountain an Sarvestan section in Fars province, Iran. The indexed microfacies are carefully determined through studying of 230 thin sections.This research shows that the indexed microfacies are mudstone, wackestone, packstone, prainstone and the amount of microfacies elements such as bioclasts, pellets, extraclasts and intraclasts. They are varied in different parts of the studied sections and the total amount of bioclasts in the section is more than other elements. The abundance of benthic bioclasts represents the regression of the basin from the open sea into the sub tidal and intertidal zone.
