Abstract :

Kuh-Shah region is one of the promising areas for Cu-Au porphyry or High-Sulfide Epithermal mineralization. Preliminary prospecting in this area, using ASTER mineral mapping in the region with some alteration, had satisfactory results. Several subvolcanic intermediate to acidic intrusive rocks, diorite to monzonite in compositions, intruded telescopically in each other and Neogene volcanic rocks. The alteration is associated with some intrusive rocks. Hydrothermal alteration zones are: argillic, silicified, quartz-sericite-pyrite, quartz-Fe-oxidecarbonate, propylitic and alunite that usually overprinted each other and it accompanied by high weathering, made it very complicated to recognize the alteration zoning. Silica-Fe-oxide-sulfide vein type mineralization is associated within strike-slip and normal fault. The mineral assemblages of the alteration and types of alteration zoning all good evidence that study area is a high sulfidation epithermal gold system.
