The Discovery of Porphyry Copper Mineralization in Xiemisitai Area of Xinjiang and Its Significance
      The porphyry copper mineralization with a certain scale was found in intermediate-acidic subvolcanic rocks after the discovery of native copper mineralization in basalts of Xiemisitai area, Xinjiang. The primary sulfides are mainly chalcopyrite, pyrite and bornite. The porphyry copper mineralization occurs mainly in the altered rhyolitic porphyry, dacitic porphyry and andesitic porphyrite, and intense epidotization, chloritization, carbonation and silicification and weak argillation occur in the mineralized rocks. This discovery shows that there are two types of copper mineralization in Xiemisitai area, and it is expected that new breakthrough can be made in further copper prospecting. The mineralized subvolcanic rocks and the hypabyssal intrusive bodies beneath the subvolcanic rocks may be the important targets for the further porphyry copper prospecting in Xiemisitai area.
