摘要
云南墨江金矿是一个大型金矿床,猫鼻梁子是其主要赋矿地段。金矿体分布于超基性岩体的围岩中。矿区各类岩浆岩中,超基性岩的含金量最高。文章应用XRD分析、扫描电镜、回归分析、线性相关分析等方法,发现了Au与Pt、Pb共生,并呈正消长关系;Au、Ag、Se的赋存关系十分密切,认为金的主要物质来源是超基性岩体。
The Mojiang gold deposit in Yunnan is a large-scale gold deposit,the Maobiliangzi gold area of which is a major ore-bearing section.The gold mineralized orebodies distributed in wall rocks of the ultrabasic rockbodies.Among kinds of magmatic rocks in the ore area,the ultramafic rocks contained the most gold.After XRD analysis,SEM,regression analysis,linear correlation analysis etc.,it has found that Au coexisted with Pt,Pb,and if Au content increase,Pt,Pb content would increase too.Furthermore,there is a cl...
