安徽省宁国地区发育众多萤石矿床（点），通过总结该地区萤石矿床的地质特征及成矿
规律，为勘查工作提供指导。萤石矿体产于燕山期花岗岩体（脉）外围，主要呈脉状赋存于震旦系及
寒武系地层中的北东向次级断裂破碎带中。矿石类型主要为萤石型、石英-萤石型及萤石-石英型3
种，矿体围岩蚀变主要为硅化、绢云母化及碳酸盐化，表明萤石矿床属于低温热液充填矿床。北东向
次级断裂、硅化等围岩蚀变及氟异常可作为本区萤石矿找矿标志。
There are many fluorite deposits
( points ) in Ningguo area of Anhui Province.
By summariz⁃
ing the geological characteristics and metallogenic regularity of fluorite deposits in this area，it provides
guidance for exploration work. The fluorite ore body is produced in the periphery of the Yanshanian granite
body (vein)，mainly in the NE-trending secondary fault fracture zone in the Sinian and Cambrian strata. The
ore types are mainly fluorite type，quartz-fluorite type and fluorite-quartz type. The wall rock alteration of
the ore body is mainly silicification，sericitization and carbonation，indicating that the fluorite deposit be⁃
longs to the low temperature hydrothermal filling deposit. North-east secondary faults，silicification and oth⁃
er wall rock alterations and fluorine anomalies can be used as prospecting indicators for fluorite deposits in
this area.
