Bagrot valley, a study area of this research, is located in Giligit district of the GilgitBaltistan province in the northern areas of Pakistan. The geology of the area is mainly comprised of the Chalt volcanics and diorites belonging to Kohistan island arc (KIA). Chalt volcanics covers most part of the study area. These are strongly deformed, metamorphosed, and intensely sheared along shear zones. The diorites occur in the southern part of the study area and have intrusive contact with the Chalt volcanics. Yellowish-brown color staining due to the oxidation of sulfide bearing phases, especially pyrite and chalcopyrite, to limonite is very prominent along the shear zones within the Chalt volcanics and also along the contact zones with diorite. At places the development of malachite and azurite are also noticed in association with the Cubearing sulfides. These sulfide bearing zones are <lm to >10m thick and are extended up to >100m.
