银峰—尤川地区萤石矿产资源潜力分析

Analysis of Fluorite Mineral Resources Potential in Yinfeng-youchuan Area

为探索银峰—尤川地区萤石矿产资源潜力,通过分析区域地质背景,运用地球化学、地球物理、钻探以及1∶1万地质填图方法对该地区萤石矿产资源潜力进行调查。结果显示:在该地区发现3处萤石矿点,矿点出露地表,形成于断裂硅化带内或边部,呈脉状、角砾状、浸染状、团块状、葡萄状产出,CaF2品位45.65%~53.92%。从多方面分析,工作区具有较大的萤石矿产资源潜力,可转入矿点普查工作。

In order to explore the potential of fluorite mineral resources in Yinfeng-youchuan area,the potential of fluorite mineral resources in this area was investigated by analyzing the regional geological background,using geochemical,geophysical,drilling and 1∶10000 geological mapping methods.The results show that three fluorite ore spots are found in this area.The ore spots are exposed to the surface and formed in or on the edge of the fault silicification zone.They are veined,brecciated,disseminated,agglomerated and grape-shaped.The CaF2 grade is 45.65%~53.92%.From various aspects,the working area has great potential for fluorite mineral resources and can be transferred to the survey of ore spots.
