山东白家店重晶石矿床地质特征及找矿方向

白家店重晶石矿体赋存于断裂构造内,按走向可分为北东向的、北西向两条矿(化)带,矿体呈脉状、透镜状产出,中生代岩浆岩及断裂均与重晶石矿的形成密不可分。主要矿物为重晶石,次为萤石、石英。通过成因分析,重晶石矿的成矿因素为区域变质作用、含矿热液及断裂构造。本矿床属中低温热液含方铅矿萤石重晶石矿床。矿体地表沿走向已经封闭,沿倾向方向均未封闭,其深部找矿潜力较大,可以作为进一步找矿勘查的靶区。

The Baijiadian barite ore body occurs in the faulted structure,and can be divided into two mineralization(north-east)and northwest-trending ore(chemical)belts according to the strike.The ore body is vein-shaped and lenticular.Fractures are inseparable from the formation of barite ore.The main mineral is barite,followed by fluorite and quartz.Through genetic analysis,the ore-forming factors of barite ore are regional metamorphism,ore-bearing hydrothermal fluid and fault structure.This deposit belongs to the medium and low temperature hydrothermal fluid containing galena fluorite barite deposit.The surface of the ore body has been closed along the strike and not closed along the inclination direction.Its deep prospecting potential is great,and it can be used as a target area for further prospecting.
