Geological Characteristics and Metallogenic Regularity of Fluorite Deposits in Ningguo Area
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.
