Loco-granite and granodiorite intrusive bodies have cut the Naiband and Sangestan Formations in Darreh-Zerreshk area in southwest margins of Shirkooh batholite. This intrusion has caused weak metamorphism and copper hydrothermal mineralization in permeable Sangestan Formation. The characteristics minerals are magnetite, chalcopyrite, pyrite, bournite and dyajenite. The studied area is composed ...
