青海某铅锌矿矿石物质组成复杂,矿块浸染严重。为了查清矿样的物质组成和矿物嵌布特征,通过镜下鉴定、化学分析、电子探针等多种手段综合研究,查明了该铅锌矿床矿石的矿物组成、结构构造、主要矿物的种类及其嵌布特征;矿石中银矿物主要为银锑黝铜矿、硫锑银矿及自然银,银主要分布于方铅矿中,其次在闪锌矿中,脉石中较少。
青海某鉛鋅礦礦石物質組成複雜,礦塊浸染嚴重。為瞭查清礦樣的物質組成和礦物嵌佈特徵,通過鏡下鑒定、化學分析、電子探針等多種手段綜閤研究,查明瞭該鉛鋅礦床礦石的礦物組成、結構構造、主要礦物的種類及其嵌佈特徵;礦石中銀礦物主要為銀銻黝銅礦、硫銻銀礦及自然銀,銀主要分佈于方鉛礦中,其次在閃鋅礦中,脈石中較少。

The composition of a Pb -Zn mine in Qinghai is complex and nuggets impregnation serious.The vari-ous comprehensive means of microscopic identification,chemical analysis and electron microprobe were used to study the ore composition and mineral distribution,finding out the ore composition,ore structure and the major minerals and their embedding characteristics.Silver in the ore mainly takes the form of silver -antimony fahlore,pyrargyrite and n-ative silver with silver mainly distributing in galena then sphalerite and little in gangue.
