摘要
排山楼金矿床是新发现的典型韧性剪切带型(糜棱岩型)金矿床,产于太古宇建平群、矿体严格受韧性剪切带中花岗质糜棱岩控制,主要赋存在蚀变长英质糜棱岩、蚀变黑云斜长糜棱岩和蚀变白云质糜棱岩中,共有4条金矿体,金品位一般在2～5g/t,矿化均匀稳定.目前正在勘探中.
Paishanlou gold deposit is a newly found typical shear zone type gold deposit (i.e. mylonitie type). It occurs in Archaean Jianping Group, with the orebodies strictly controlled by granitic mylonite in ductile zone and mainly hosted by altered felsic mylonite, altered biotite-plagioclase mylonite and altered dolomitic mylonite. There are four gold orebodies altogether. The average grade of Au is 2 to 5 gram per ton and the mineralization is stable. It is now still being prospected.
