Microbiostratigraphy of the sediments of Talezang Formation in Ghalebi section (southwest lorestan, Iran)

In the present paper, Talezang Formation, located in southwest of Khoramabad, was studied. Ghalebi section (200m thickness) contains gray limestones with cherty nodules and sandy limestone isoclinally overlies Amiran Formation (gray shale and limestone). It is underlain concordantly and discontinuously by Kashkan Formation.160 samples were surveyed (examined) from the section; 28 genera and 4 species of benthonic foraminifera and 6 genera and 2 species of algae were identified. Due to similarity between identified benthonic foraminifera and Miscellanea- Kathina Assemblage Zone; the age of Talezang Formation can be assumed late Paleocene (Thanetian).
