湖南长源铅锌矿成矿地质特征及成因初探

Preliminary study on geological characteristics and genesis of Pb Zn deposits in Changyuan,Hunan

长源铅锌矿位于幕阜山岩体南部,湘东北多金属成矿带上。矿脉严格受断裂构造控制,成矿物质来源于冷家溪群地层及燕山晚期花岗岩体,岩浆活动为成矿提供热源,成矿流体主要沿北东向的区域压扭性断裂和次级北西向、南北向张扭性断裂构造流动迁移,在构造有利部位富集,形成中-低温热液充填型矿床。

Changyuan lead-zinc deposit is located in the south of Mufu mountain rock, Northeastern Hunan polymetallic metallogenic belt. The veins are strictly controlled by fault structures, The ore-forming materials come from Lengjiaxi Gr and Late Yanshan granite, Magmatic activities provide heat source for mineralization, The ore-forming fluid flows mainly along the Regional North East trending Compression fracture and Secondary North West, north to South Tensional fracture, Enrichment in favorable tectonic sites to form the meso-epithermal filling deposit.
