摘　　要：通过对广东石人嶂钨矿床51件样品银含量的测试：Ag〉10-6的占58.82%,其中有7件Ag〉100×10-6,最高1304.4×10-6,表明伴生银矿化普遍而强烈。通过对光、薄片进行显微镜下鉴定、扫描电镜分析,初步查明银矿物种类有碲银矿、银硫铋矿及含银矿物。该矿床银的存在形式主要有两种：一是银呈类质同象存在于铅铋硫盐矿物中,如斜方辉铋铅矿、辉铅铋矿、硫铋锑铅矿、斜方硫铋铅矿等均含一定量的银,或局部呈固溶体状态形成铋铅银矿,并以这种形式存在为主,本矿床中含量较多的铅铋硫盐矿物是辉铋矿、斜方辉铋铅矿,其中斜方辉铋铅矿普遍含一定量的银,含银量在1%-9%;另一种是以独立银矿物形式存在,如碲银矿、银硫铋矿。There are 51 samples have been tested,which found out Ag〉10-6 in accounting for 58.82% in Shirenzhang tungsten deposit of Guangdong,and among them,7 samples show Ag〉100×10-6,the highest up to be 1 304.4×10-6,above these show that associated silver mine are universal and strong.According to microscope analysis and scanning electron analysis for gloss coal and flake,there are hessite,matildite and contain sliver mineral in the firstly identify.The silver has two main forms existence in the deposit,the first one is isomorphs existence in the lead-bismuthd-sulfosalt minerals,for example cosalite,bismutoplagionite,tintinaite,bonchevite and so on,and some show sosoloid schirmerite,this form is very popular in the deposit.The deposits has more lead-bismuthd-sulfosalt minerals which are bismuthine and cosalite,and the cosalite contains sliver 1%-9%.The second one is independent mineral,for example hessite,matildite.
