| 摘 要： | 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、化民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－Ａｂ两类矿石中。

| Abstract: | On the basis of the results of mineral's EMS, chemical analysis and microscopic observation of minerals microscope, combined with ore's field occurrence, physical character, ingredient property of silver the occurrence of silver in the Yinchangpo primary silver deposit in Northwest Guizhou were examined. Three silver minerals including freibergite, native silver and argentite have been found. There is a strongly positive linear correlation between the mole numbers of antimony and silver in freibergite. Silver occurs predominantly as independent argentiferious minerals in two different ores: Pb\|Zn\|Ag\|type and Pb\|Cu\|Ag\|type ores. |
