摘要
新疆察汗萨拉锑矿床位于西南天山中部的萨阿尔明晚古生代沟弧带的西段,它与萨瓦亚尔顿金锑银矿、卡拉脚古牙锑金矿、古勒克达坂卡堤锑金矿构成察汗萨拉锑金矿带。矿区总体受控于一大型逆冲推覆构造带,处于查汗沙拉锑异常区浓集中心域内,矿体产于阿尔腾克斯组含炭碎屑岩中,显示多元素多期次的成矿特征。成矿物质来自于赋矿地层,成矿热液则是由岩浆水和天水组成的混合水,属沉积改造型锑银多金属矿床。
Chahanshala Sb deposit is located in the center part of southwestern Tianshan which belongs to the western part of late Paleozoic trench-arc zone in Xinjiang, and constitutes the Chahanshala Sb-Au mineralizing belt with Shawayaerdun Au-Sb-Ag deposit, Kalajiaoguya Sb-Au deposit, and Gulekedabankati Sb-Au deposit. The mineral district sits on the concentrated center of the Chahanshala Sb abnormal area and is controlled by a huge thrusting nappe structure. The orebodies are in the carbon-bearing fragmental rock of the Aertengkeshi formation, and demonstrate the character of multi-element and multi-stage mineralization. The ore-forming material came from the formation that hosts the orebodies, and the ore-forming fluids were mixed solution of magmatic water, meteoric water, and metamorphic water.
