摘　　要：吉林省桦甸市锦山金矿赋存于太古代花岗质片麻岩中,矿体受北西向断裂构造控制,与燕山期辉绿岩脉关系密切。矿体呈脉状、扁豆状,矿石结构一般以自形粒状为主,构造以块状、条带状为主。矿石自然类型有含金多金属石英脉型及含金多金属蚀变岩型,矿石工业类型为原生硫化物矿石。矿床成因为岩浆热液脉型金矿床。在综合分析前人资料的基础上,建立了物探、化探和地质找矿标志。Jinshan gold deposit in Huadian City, Jilin Province occurs in Archean granitic gneiss. The ore body is controlled by NW trending fault structure and is closely related to Yanshanian diabase vein. The ore body is vein and lentil shaped. The ore structure is generally euhedral granular, and the structure is mainly massive and banded. The natural types of ore include gold-bearing polymetallic quartz vein type and gold-bearing polymetallic altered rock type. The industrial type of ore is primary sulfide ore. The genesis of the deposit is magmatic hydrothermal vein type gold deposit. Based on the comprehensive analysis of previous data, geophysical, geochemical and geological prospecting indicators are established.
