Abstract :

The study area is located at SouthWest of Keriz village, 30 km NorthWest of Kashmar. Based on field and mineralogical studies, the rocks are mainly: Plutonic Units(syno granit, hornblende diorite, hornblende quartz diorite, hornblende pyroxene diorite), Sub-volcanic Units (diorite porphyry, porphyry hornblende diorite, porphyry Pyroxene hornblende diorite, , porphyry hornblende pyroxene diorite , porphyry biotite hornblende diorite, porphyry pyroxene biotite hornblende diorite, porphyry monzodiorite, porphyry hornblende pyroxene monzonite, porphyry pyroxene hornblende monzonit, porphyry pyroxene monzonite) and Volcanic Units(andesite, pyroxene andesite and tuff). All these rocks are well surrounded by Carbonate Unit in the area. All igneous rock units are strongly altered by hydrothermal fluids, forming Propylitic Zone, Carbonaceous Zone, Siliceous Zone and Argilliceous Zone, and or combination of these. The study area is located in Khaf- Kashmar-Bardascan Plutonic – Volcanic Belt. Therefore detailed study can determine the Fe mineralization system in the area. Magnetic Susceptibility of Plutonic Units were measured up to 6905×10-5 SI., proving that the mineralization in this area may be related to I type Granitoids.
