摘　　要：骨洞坑萤石矿床位于浙东南褶皱系北东向江山——绍兴深断裂和余姚——丽水深断裂所夹持的余姚——遂昌前震旦纪变质基底隆起带南东侧附近。骨洞坑萤石矿受建造和构造双重控制;其成矿物质来源于围岩,控矿主断裂为NW-NWW向压扭性断裂。经过多次的野外实地调查,结合区域萤石矿成矿特征,本文从物源、水源和热源三个方面论述骨洞坑萤石矿床成因,详细论述了成矿热流体场的形成过程,并建立了成矿模式,为今后骨洞坑萤石矿床地质探矿提供一定参考依据。Geotectonically,the Gudongkeng fluorite deposit belongs to system of the southeastern part of Zhejiang province.It lies nearby the southeastern part of Yuyao-Suichang Presinianperiod metamorphosed basement upheaval,which is controlled by two NE trending deep fault,Jiangshan-Shaoxing deep fault and Yuyao-Lishui deep fault.The Gudongkeng fluorite deposit is controlled by formation and structure.The metallogenic material was from wall rock and the ore control major fault is NW-NWW-trending compressoshear faults.After many times field survey,combining the ore forming characteristics of territorial fluorite deposit,this text discussed the origin from three aspects of material source,water source and thermal source,discussed the forming process of ore solution in detail and established the metallogenic model to provide some reference for the exploration of the Gudongkeng fluorite deposit in the future.
