摘　　要：新疆东昆仑祁漫塔格东段区域化探成果显示,在该区近地表地质体中,Na2O、K2O、Sn、W、Bi、Be、U、Al2O3、Ba、SiO2、Pb、Th等元素相对富集,主成矿元素为W、Au、Bi、Sn、Nb、Pb、F等,经异常查证先后发现了白干湖钨锡矿、蟠龙峰铁多金属矿、维宝铅锌矿等;在本区以W、Sn等为代表的高温元素的成矿作用与华力西期和加里东期岩浆侵入活动关系密切,印支期中酸性岩浆的侵入与区内Cu、Pb、Zn、Mo等中—高温元素的成矿作用具有较密切的关系,层控改造型Pb、Zn矿床与蓟县系狼牙山组碳酸盐岩-细碎屑岩建造有关,而Au元素的成矿作用则与燕山期的岩浆活动有关。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.
