广东省海丰县召贡铅锌矿区地质特征与找矿标志

Geological characteristics and prospecting criteria of Zhaogong lead-zinc deposit, Haifeng County, Guangdong Province

广东省海丰县召贡地区位于武夷成矿带南段、莲花山断裂带南西段,通过对区内1:10000专项地质填图、1:1万土壤测量、槽探工程揭露及相关测试分析发现,检查区内共发育2条铅锌矿(化)体,V1、V2,两条矿化体呈长条带状、透镜状赋存于受北西向压扭性断层影响的花岗质糜棱岩带中。初步认为矿床成因类型为受动力变质改造的岩浆期后热液充填交代型矿床,为粤东地区进一步的找矿工作提供了指示性意义。

Zhaogong area,Haifeng County,Guangdong Province,is located in the southern segment of Wuyi metallogenic belt and the southwest segment of Lianhuashan fault belt.Through 1:10000 special geological mapping,1:10000 soil survey,trough exploration project expose and related test analysis,it is found that there are two lead-zinc mineralization bodies (V1,V2) in the area.The mineralized bodies occur in two elongated lenticular granitic mylonite belts affected by nW-trending compression-torsion faults.It is preliminarily considered that the genetic type of the deposit is postmagmatic hydrothermal filling metasomatism deposit transformed by dynamic metamorphism,which provides indicative significance for further prospecting in eastern Guangdong.
