广东省石园铅锌矿地质特征及找矿前景

THE GEOLOGICAL FEATURE AND PROSPECTING POTENTIALITY OF SHIYUAN PB-ZN DEPOSIT IN GUANGDONG

广东省石园铅锌矿矿体呈脉状、透镜状赋存于南北向断层构造破碎带中,矿体产状和断层构造带产状基本一致。铅锌矿体赋矿围岩均为片麻状花岗岩。铅锌矿化与硅化、黄铁矿化关系密切,属于热液交代型多金属矿床。区域上该矿区处于阳春-新兴多金属成矿带,矿化除Pb、Zn之外,还共生或伴生Ag和Au。区内含矿构造破碎带规模较大,矿化连续,深部有变宽趋势。显示石园地区有较好的找矿前景。

Th oreboy of Shiyuan Pb-Zn deposit in Guangdong is veined,lenticular in the NS fault fracture zone.The orebody occurrence consists basically to that of the fault zone.The wall rock of Pb-Zn orebody is the gneissic granite.The Pb-Zn metallogenesis is in close relation to signification,pyritization.It is a hydrothermal metasomatic multimetallic deposit.Regionally,this orefield is in Yangchun-Xinxing multimetallic metallogenesis zone.There is the paragenetic or associated Ag,Au metallogeneis besides Pb,Zn.In this area,the ore-bearing fracture zone scale is large,metallogenesis continuous,and widened in the deep,showing the good prospecting potentiality in Shiyuan area.
