摘要：清流县赤坑萤石矿矿体主要呈大脉状和长透镜状，赋存于碎裂似斑状中粗粒正长花岗岩的北东向断裂带中。该断裂带既是导矿构造，又是储矿构造，其矿体形态、产状严格受到断裂控制。基于此，分析清流县赤坑萤石矿的地质特征及成因。

Abstract： The ore body of the Chikeng fluorite mine in Qingliu county is mainly in the form of large veins and long lenses， occurring in the northeast trending fault zone of fragmented porphyritic medium coarse grained syenogranite. This fault zone is both a mineral conducting structure and a mineral storing structure， and its ore body morphology and occurrence are strictly controlled by the fault. Based on this， analyze the geological characteristics and genesis of the Chikeng fluorite mine in Qingliu county.
