Abstract
In this study, 60 samples have been studied from Carboniferous deposits of Khames stratigraphical section, 10 Km southeast of Khalkhal. The marine sequence of Khames stratigraphical section is about 163.5 m. thick and consists of gray to black Limestone and dolomitic limestone. The lower boundary of the under study section marked with yellowish limestones of Cretaceous and dark Sills with Faulted contact. The upper boundary of the Carboniferous strata is covered with Pliocene Polygenetic conglomerate disconformably. The Carboniferous unit studied here has not been named so far, so in this research, we have attempted to identify the stratigraphical position of the mentioned sequence. In this research 30 genera and 25 species of benthic foraminifera were identified similar to those reported from carboniferous strata of Qezelqaleh, Bagher Abad, Mobarak and Sardar formations suggesting a Late Visean to Early Bashkirian age for the Khames Carboniferous marine sequence.
