新疆若羌县鸭子泉地区金铜矿地质特征及潜力分析

Geologic features and mintral potential of Yaziquan Au-Cu deposit,Ruoqiang County,Xinjiang

若羌县鸭子泉地区位于塔里木-华北板块(Ⅰ)南部,柴达木微陆块(Ⅱ)南缘的祁曼塔格加里东褶皱系,阿尔金断裂带及白干湖断裂、鸭子泉构造混杂岩带等次级构造为该区提供了铜及多金属迁移、富集的广阔空间,文章通过地球化学异常特征的研究认为多期次的构造-岩浆活动,形成的金铜矿体与元素异常特征相吻合。经统计岩屑异常在矿区中部连续性好、面积大、衬度高的铜异常,与金异常相伴生,且发现多条铜金矿(化)体。铜异常在区内分布稳定,与鸭子泉构造混杂岩带吻合,形成了以铁、铜、钼、多金属为特色的造山型构造成矿带。

The paper studied geologic features of Yaziquan Au-Cu deposit,Ruoqiang County,Xinjiang.Through the study of the geochemical anomaly characteristics,it is considered that ore deposit had been formed by multiphase tectonic,magmatic activities.The Au-Cu ore body coincides with element anomalous characteristics.The debris anomalies show better continuity,large area and high Lining degrees in the central part of the mining area,and associated with Au anomalies,there are some Au-Cu ore bodies,Cu anomalies show stable distribution,forming orogenic metallo-tectonic zone with iron,copper,molybdenumetc,in the study area.
