通过电子探针、化学分析、显微镜鉴定及野外观察等方法 ,对贵州威宁银厂坡银矿床的银矿物物理性质、化学成分特征及银的赋存状态进行了研究。初步查明 ,银矿物主要有三种 :自然银、螺硫银矿、银黝铜矿。在银黝铜矿中 ,Ag的摩尔数与Sb、Zn的摩尔数呈明显正相关。银主要呈独立银矿物的形式赋存于Pb Zn Ag和Pb Cu Ag两类矿石中
The silver mineral physical properties, chemical composition characteristics and silver occurrence status of Yinxianpo Silver Deposit in Weining, Guizhou Province were studied by means of electron probe, chemical analysis, microscopic identification and field observation. Preliminary identified, there are three main types of silver minerals: natural silver, spirulina silver, silver tetrahedrite. In the silver-tetrahedrite, the number of moles of Ag is positively correlated with the number of moles of Sb and Zn. Silver is mainly in the form of independent silver minerals in Pb Zn Ag and Pb Cu Ag two types of ore
