摘　　要：新疆东昆仑存在一条长达700km的锑异常带，在新疆该带锑元素富集程度最高、富集规模最大。西段的黄羊岭地区，已发现大面积锑矿化，其中的黄羊岭锑矿由4个长1000～1500m、宽200～400m的矿化带组成，含矿岩系为二叠系黄羊岭群碎屑岩，带内各类矿化脉体发育，锑矿化与石英脉关系密切，品位较富，呈现脉状矿化的特点，其资源远景在大型矿床规模以上。通过锑元素富集特征、控制因素、锑矿化特征及其与异常关系的研究，认为东昆仑地区具有寻找大型锑矿的地质-地球化学条件，该区资源潜力巨大，是新疆最有希望找大型锑矿的地区。There exists a Sb anomalous belt of 700 km long in the eastern Kunlun Mountains, which represents an area of most intensive and wide enrichment Sb in Xinjiang. A large scale of Sb mineralization has been discovered at Huangyangling in the western part of this huge Sb anomalous belt. The Huangyangling Sb deposit contains four mineralization zones with the length of 1000 - 1500 m and width of 200 - 400 m each. A series of mineralized veins occurred in the detrital rocks of the Permian Huangyangling Group. The Sb mineralization with high-grade ores is closely related to the quartz veins. The Huangyangling Sb deposit may be a potential giant one. On the basis of Sb enrichment coefficient, orecontrolling factors, and spatial relationship between Sb mineralization and anomaly, we suggest that the eastern Kunlun Mountains be of favorable geological, metallogenetic and geochemical conditions to host large or super-large Sb deposits in Xinjiang.
