The Jinjing gold deposit is a representative gold deposit in the Xiada-Jinjing gold field in southeastern Guizhou Province.Based on the field geological observation,this paper presents the ore characteristics of Jinjing gold deposit in detail.Besides,the anthors systematically studied the occurrence of gold in the deposit.The Jinjing gold deposit belongs to the poor sulfide quartz vein type gold deposit,and the ore body occurs in the form of gold bearing quartz veins in the inter-layer sliding zone of the two wings of the Jinjing anticline.The main ore mineral is(containing silver)natural gold.The hy-drothermal metallogenic stage of the Jinjing gold deposit is divided into quartz-gold stage(S1),quartz-arsenopyrit-gold stage(S2),and quartz-polymetallic sulfide-gold stage(S3).Gold in the deposit can be divided into"visible gold"and"invisible gold".The"visible gold"is mainly native gold with high fineness,which exists in quartz,pyrite,arsenopyrite,copper pyrite,galena and sphalerite in the form of fissure gold,wrapped gold and intergranular gold.The"invisible gold"occurs in pyrite and other sulfides in the form of nano gold and solid solution gold.The research results provide important basis for in-depth research on the genesis of ore deposits and the improvement of ore dressing and smelting technology.
