Abstract

Geological map of Goltapeh in an area of 625 Km2 on the border of Hamedan and Kurdistan provinces. Based on geological divisions of Iran, the studied area located in north of Sanandaj-Sirjan zone with complex deformations and sub-zone of Hamedan phyllites. The rock units in this map are of those metamorphic, sedimentary and igneous rocks are exposed of the Late Jurassic until Quaternary time range. Based on the information from field traverses, laboratory results, absolute age dating and microscopic studies, some changes were applied in stratigraphical status of rock units compared to the base maps. The age of protolith of low-grade metamorphic tocks is presumably late Jurassic. Exposed lavas have been formed in late Miocene. Intrusive rocks including granite, diorite and gabbro were reported for the first time in the area and their age was considered post-early Eocene. In deposits equivalent to Qom Formation of Early Miocene, three units were recognized and their age was determined to be Early Miocene and not Oligocene. Using the stratigraphic situation, the pyroclastic sequence and the lavas above and under that assumed to be of Middle-Late Miocene age. Pliocene and Quaternary sediments have significant variety and distributed in studied area.
