Regional geochemical exploration and ore-prospecting effect in eastern Qimantag, Xinjiang

Regional geochemical prospecting results in eastern Qimantag of East Kunlun show that, in the near-surface geological body, Na2O, K2O, Sn, W, Bi, Be, U, Al2O3, Ba, SiO2, Pb and Th are relatively abundant, with Au, Bi, Sn, Nb, Pb and F being the main metallogenic elements. Based on anomaly investigation, the authors discovered several ore deposits such as Baiganhu W-Sn deposit, Panlongfeng Fe polymetallic deposit, and Weibao Pb- Zn deposit. In this area, the ore- forming activities of high temperature elements represented by W and Sn were related closely to Variscan and Caledonian magmatic intrusive activities, the ore-forming activities of mid-high temperature elements such as Cu, Pb, Zn and Mo were intimately related to Indo-Chinese acid-intermediate magmatic intrusive activities, the stratabound transformed Pb, Zn ore deposits were connected to the ore-bearing formation of fine clastic rocks-carbonate rocks of Langyashan Group, and the mineralization of Au was related to Yanshanian magmatism.
