摘要: 新疆查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等构成查汗萨拉锑金矿带。矿区总体受控于一大型逆冲推覆构造带,处于查汗萨拉锑异常区浓集中心域内。矿体产于下泥盆统阿尔腾克斯组含炭碎屑岩中,显示多元素多阶段成矿特征。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。Abstract: Chahansala Sb deposit is located in the centre section of southwestern Tianshan which belongs to the western part of Late Paleozoic trench-arc zone in Xinjiang.And it constitutes the Chahansala Sb-Au deposit zone with the Shawayaer dun Au-Sb-Ag deposit the Kalajiaoguya Sb-Au deposit, and the Gulekedabankati Sb-Au deposit.The mineral district sits on the concentrated centre of the Chahansala Sb abnormal area and controlled by a huge thrusting nappestructure.The ore bodies are in the carbon-bearing fragmental rock of the Aertengkeshi formation, and demonstrate the character of multi-element and multi-stage mineralization.The minerogenic material is from the formation that contains the ore bodies, and the minerogenic hydrotherm is the mixed solution that contains the magmatic water, meteoric water, and metamorphic water.
