摘　　要：本文利用矿相显微镜和电子探针研究水南银矿银的赋存状态。发现该矿银主要以自然银的形式存在,自然银多呈粒状、片状或树枝状嵌生在石英中。银矿物除自然银外,还见有后期铜的硫化物交代自然银形成的含铜辉银矿。The silver occurrence in Shui-Nan Silver Mine was studied with the help of mineralogical microscoPe and electronic Probe.Silver minerals in this mine mostly occurred as native silver embedded in quartz and shaPed into grained,schistose or tree-like structure.It was also found that, besides native silver, there existed coPPer-bearing argentite which seemed to be an alternation Product through the replacing of native silver by late-formed copper sulfide.
