Abstract

The study area is located at 130 km northwest of NEHBANDAN in South of Khorasan and is a part of the rectangular Chahvak (Dehsalm). Dacite, rhiodacite, andesite, rhyolite, tuff and lithic tuff with Eocene age are recognized in the study area. According to mineralogy, mentioned rocks include plagioclase, quartz, pyroxene, amphibole, biotite and alkaline feldspar. Plagioclase consists of zonal structure and amphiboles include a burned rim that this phenomenon is a sign of high temperature magma. Based on chemical classification, studied rocks are andesite, truckyandesite, andesitic basalt, rhyolite, dacite and rhiodacite. According to the petrologic graphs, the studied rock magmatic series have a nature ultraptasic CALC-ALKALINE, Also by using from the separator graphs of tectonic setting, mentioned volcanic rocks have been located in SUBDUCTION zones. Negative anomaly of elements P, Nb and Ti and positive anomaly of Pb and K in these rocks indicate the similarity of chemical properties of these rocks with VOLCANIC ARCs magmatism.
