Abstract

The Kouh.- e- Zar (Toroud) ‘s arc is made of a volcano- plutonic magmatic Complex, with andesitic and granodioritic composition. The Platons are tought to be in the forms of sub volcanic stocks intruding into pyroclastic deposits of the area. The magmatism of the suidied area is considered to be of calcoalcalin type, and its andesaites lay in orogenic andesites suit. The volcanism of the region is superficial manifestation of deep situated plutonics, which both originated from a unic magmatic source. According to the Ewart’s classification of magmas, the magmatic arc of the region is of compressional type. The widespread copper mineralization and its sulfied minerals in the region related to this volcano plutonic arc, that is presented here as a linear arrengement. The zonal alteration around the Baghou granodioritic stock is closely related to copper porphyry mineralization of the region.
