Abstract: | Geological setting Jiama copper\|polymetallic deposit is located at Maizhokunggar county, more than 20km away from the county town. Tectonically, it lies in the eastern sector of the Gangdise volcanic arc, occurring in the Jiama\|Rutog interarc basin. The interarc basin lies between the Poindo\|Songduo Mesozoic island chain zone in the northern side and the Jurassic\|Cretaceous south Gangdise island arc zone in the southern side. Jurassic marine carbonate and Cretaceous paralic clastic rock are exposed in the basin. Late Yanshan\|Himalaya tectonic deformation and magmatic veins are well developed. These provide good conditions for forming the copper\|polymetallic ore deposit. Jiama copper\|polymetallic deposit is the only large one explored in the Gangdise volcannic arc. |
