云南开远市上米者一带锑矿成矿条件及找矿潜力分析

滇东南是我国重要的锑矿分布区，近年来先后发现了广南县木利锑矿、开远大庄都比和余米都锑矿床。开远上米者锑矿（点）是近期矿产地质调查中发现的锑矿（点），锑矿体赋存于个旧组下段碳酸盐岩与飞仙关组碎屑岩组成的断裂破碎带中，主要矿体靠近飞仙关组一侧，赋存于泥质粉砂岩与碳酸盐岩的界面上，属低温热液型矿床；通过开展矿区地质、物化探找矿工作，在综合研判成矿地质条件基础上圈定了上米者锑矿预测区；该预测区内锑元素异常强度大、浓度分带明显，且与成矿地层、构造条件叠合程度高，值得开展进一步找矿工作。

Ore-forming conditions and prospecting potential of antimony deposits in Shangmizhe area of Kaiyuan city, Yunnan province

The Southeast Yunnan Province is an important antimony deposit distribution area in China. In recent years the Muli antimony deposit in Guangnan county and Dazhuangdubi and Yumidu antimony deposits in Kaiyuan city have been discovered in the area. Shangmizhe antimony occurrence is recently discovered during geological mineral resources survey. Antimony ore body occurs in a fault cataclastic zone consisting of carbonatite of the Lower Member of Gejiu Formation and clastic rock of Feixianguan Formation. The main ore bodies are located at the interface of argillaceous siltstone and carbonatite close to the Feixianguan Formation. It is a epithermal antimony deposit. On the basis of comprehensive study and metallogenic geological conditions, the Shangmizhe antimony ore prediction area is delineated with strong antimony element intensity and obvious concentration zoning. It supeimpose the metallogenic strata and structure thus is worthy of further prospecting.
