摘要
我国萤石矿主要分布在27个省(直辖市、自治区),从矿床规模看,以大中型为主;按成因类型可划分为:热液充填型、沉积改造型和伴生型,以热液充填型、沉积改造型萤石矿为主;我国大多数萤石矿的成矿温度都低于300℃,属于中低温热液矿床;大气降水在我国萤石矿成矿过程中起着非常重要的作用。
The fluorspar mine of China are mainly distributed in 27 provinces （municipalities and autonomous regions）,which mainly are large and medium-sized mine from the deposit scale; The fluorspar deposits in China is divided into three types of hydrothermal filling deposits,sedimentary reelection deposits and associated deposits on genetic types,which mainly are hydrothermal filling deposits and sedimentary reelection deposits,which are ore-forming temperature below 300℃ and are middle-lowtemperature hydrothermal deposits; meteoric water plays a very role in ore-forming process of fluorspar mine in china.
