新疆西昆仑-阿尔金成矿带区域地球化学勘查进展

A Progress of Region Geochemical Exploration of Metallogenic Belt from West Kunlun to Altun Ranges in Xinjiang

国土资源大调查在西昆仑-阿尔金成矿带部署完成1∶20万区域化探76701km2、1∶50万区域化探73837km2,实现了该成矿带区域化探工作的全面覆盖,为矿产资源评价和基础地质研究提供了系统地球化学资料。异常查证直接发现了维宝铅锌矿、黄羊岭锑矿等一批找矿信息,评价工作证实维宝铅锌矿已具中型规模,有大型远景;圈定的新疆东昆仑锑、西昆仑岔路口铅等规模巨大的元素富集区具有重要找矿意义。后续工作先后在黄羊岭地区发现锑矿床(点)14处,这是新疆第一个锑矿化集中区;在岔路口一带发现了多宝山、甜水海、宝塔山等铅锌矿、卡子勒铜银矿和一批矿产信息,使之成为新疆重要矿产勘查区。地球化学勘查效果显著,有力推动了西昆仑-阿尔金地区矿产资源调查评价工作。

There have been finished about 76 701 km2 with scale 1 ： 200,000 and 73 837 km2 with scale 1 ： 500,000 regionally geochemical exploration in West Kunlun-Altun mineralization belt during the land and resources survey. It covered totally the whole mineralization belt, and provided systematical geochemical data for the mineral resources appraisal and basic geological research. The prospecting information such as lead-zinc ore in Weibao and antimony ore in Huangyangling has been found by anomaly investigation and verification. Evaluation proved that Weibao lead-zinc deposit had a medium size, in a prospective large scale; The large element enrichment regions determined with geochemical methods, such as antimony in east Kunlun and lead in Chalukou of west Kunlun in Xinjiang are significant for the prospects. In subsequent work,14 antimony deposits （spots） had been found successfully in Huangyangling area, whichwas the first antimony mineralization concentration region in Xinjiang; The lead-zinc ore deposits such as Duobaoshan, Tianshuihai and Baotashan, and Kazile copper-silver ore deposit, with a batch of mineral information in addition, were found in Chalukou area, which became an important mineral exploration area in Xinjiang. The geochemical exploration with remarkable effect forcefully promoted the work of mineral resources evaluation in west Kunlun-Altun region in Xin- jiang.
