Abstract

The Vehnoveh area situated about 60km south of Qom in Orumieh-Dokhtar volcanic zone. Most of rocks of this area are middle and upper Eocene. Volcanic rocks combination consists of BASALTIC ANDESITE, Andesitic basalt, Olivin basalt, Olivine dolerite, Crystal lithic tuff and Andesite megaporphyr. Delayed magmatism accompanied with the Eocene volcanic phase has caused a series of lava flows and a lot of dikes in this area. These dikes and flows have a combination of Andesite to differented Andesites towards the Albitite pole and contain gabbroic enclaves. In this area, traces of COPPER mineralization and ancient mines works are seen. The main COPPER minerals are Malachite, Chalcosite and Covellite. Mineralization is limited to a bedded horization of BASALTIC ANDESITE lava with Amigdaloidal texture; therefore, it is considered as a mineralization of stratabund type. The Most of mineralization textures are veins and veintels type and filler of vesicles. The consideration placed of in to the Epithermal class and it can be compared with the MICHIGAN TYPE.
