Abstract

Koohrig intrusive mass is located in the east of Rafsanjan, Kerman Province, Iran and it is part of because it has cut the sandstone, limestone, shale units and conglomerate of Upper Cretaceous. Its intrusive rock includes quartz, plagioclase and alkali feldspar and its ferromagnesian mineral which is biotite has changed into chlorite. This Intrusive mass is characterized by the presence of metamorphic geochemical studies led to the detection of granite and granodiorite and quartz monzonite rocks.

Summary

Introduction

The study of igneous intrusive rocks has been concerned from long ago. The majority of granitoid intrusive rocks of Iran have been located in the area of Central Iran, Sanandaj-Sirjan zone and Urumieh-Dokhtar belt. Koohrig granitoid intrusive mass is a very small stock, its area is about Koohrig which is located in the north of village Robat from Baghin, Kerman and on the southern slopes of Mount Badamo-Arjasb. The distance of this mountain is about 7 km from asphalted road Rafsanjan-Kerman and the mountain Gabri is located around 5 km of west (Figure 1). Wind erosion is very intense in the south of this area It seems that Koohrig name is taken from the wind dunes spreading on its southern slope. Metamorphic aureole has a range of hornfels, calc-silicate, tactit, marble and hydrothermal delay streak. [2] A number of basaltic and andesitic dikes have cut the granitoid stock in the fringe
