摘要
中国作为全球最大的黄金生产国和消费国之一,金矿资源对外依存度高,加大勘查开发力度至关重要。星星峡东山地区所在的东天山作为新疆重要矿产资源基地,金及多金属成矿潜力显著。基于矿产地质调查,以星星峡东山地区为研究对象,通过野外勘查、探槽工程及地球化学分析,新发现红星山金矿点、东铅炉子铅矿床及4处铜矿点(转井、转井东、东山、东山东)。研究表明,星星峡东山地区金成矿类型可能是斑岩型成矿系统的一部分,即浅成低温热液型;铜成矿类型可能是岩浆热液脉型;新发现的铅矿床可能是钼成矿系统的远端端元。星星峡东山地区具有金、钼、钨、锡、铜勘查潜力,同时可能存在斑岩型钨-锡及钼矿。
As one of the world’s largest gold producer and consumer,China faces a high dependence on imported gold resources,making intensified exploration and development efforts essential.The Eastemn Tianshan region,where the Dongshan area of Xinxingxia is located,serves as a key mineral resource base in Xinjiang and exhibits significant potential for gold and poly metallic mineralization.Based on a mineral geological survey,this study focuses on the Dongshan area and integrates field investigation,trenching,and geochemical analysis.New discoveries include the Hongxingshan gold occurrence,the Dongqianluzi Lead Deposit,and 4 copper mineralized sites(Zhuanjing,Zhuanjing East,Dongshan,and Dongshan East).The findings suggest that the gold mineralization in the Dongshan area may be part of a porphyry-related system,likely representing an epithermal low-temperature hydrothermal type.The copper mineralization is inferred to be of a magmatic-hydrothermal vein type,while the newly identified lead mineralization may represent a distal expression of a molybdenum system.Overall,the Dongshan area of Xinxingxia shows significant exploration potential for gold,molybdenum,tungsten,tin,and copper,and may also host porphyry-type W-Sn and Mo deposits.
