摘　　要：该矿床为低硫化物含金石英脉矿床，自然金为矿床唯一金矿物，其成色高达９８３３４‰～９８４１０‰；细粒金（００３７～≥００１ｍｍ）占２９％，微细粒金（＜００１ｍｍ）占６６％，巨、粗粒金罕见；自然金的赋存状态以粒间金居多（占６７１％），次为包裹金（占２６６％），而裂隙金少见（占４３％）；产出形态以浑圆粒状（占３８％）、尖角粒状（占２５４％）、枝叉状（占１５２％）居多、角粒状。This ore deposit is a lowsulfide gold-bearing Quartz-vein deposit The native gold is an only gold mineral of this ore deposit, the fineness modulue of which is high as 98334‰～98410‰,Fine-grained gold (0037～≥001mm) consists of 29%, micro-fine-grained gold (<001mm) consists of 66%, and macrograined and coarse-grained gold is rare Intergranular gold occurs predominately (671%) in the existence state of native gold,the next is in the form of inclusion (266%), and fissure gold is rare (63%) The occurring shape is mostly perfectly round-granular(38%), sharply angular-granular (254%) and branch (152%), but breccia and wheat-granular and acicular shape is rare
