西南天山金锑成矿带成矿远景

中国新疆西南天山是中亚南天山金和有色金属成矿带的东延部分,成矿潜力巨大.分析了区域成矿背景,总结了金、锑成矿规律,划分了6个成矿带和15个金、锑成矿区,对4个重点成矿区的成矿远景进行了分析.指出萨瓦亚尔顿河上游、乌兰赛尔-萨恨托亥、乌什北山、哈尔克成矿带的西北部、查汗萨拉、卡拉脚古牙应作为首批重点研究和找矿靶区.提出穆龙套型金矿应作为主攻类型,对于锑矿应重视碳酸盐岩与碎屑岩接触部位的破碎带,并注意锑与其他金属的共生规律.

Ore-forming prospects of gold-antimony metallogenic belt in Southwestern Tianshan Mountain of Xinjiang,China

The Southwestern Tianshan Mountain in Xinjiang is the eastward extension of South Tianshan Mountain in Central Asia. It is a gold and nonferrous metallogenic belt and has brilliant ore-forming (potentiality). This paper analyzes its regional metallogenic background, summarizes the metallogenic (regularity) of gold and antimony, divides it into six metallogenic belts and fifteen gold and antimony (metallogenic) provinces, and analyzes the ore-forming prospects of the four main metallogenic provinces. It points out that the upper reach of the Sawayaerdun river, Wulansaier-Sahengtuohai, Wushibei Mountain, northwestern of the Haerke metallogenic belt, Chahansala and Kalajiaoguya are the first group of mainly studying areas and ore-hunting target areas. The Muluntau type gold deposit should be treated as the main type. In order to look for antimony deposits, people should focus their attention on the interlayer shattered zone at the contact between carbonate rocks and clastic rocks and pay their attention to the paragenetic (regularity) of antimony and other metals.
