中文摘要:
      十七道沟金矿点位于吉林省临江市长白县西侧30km处,与亚洲第一大铜矿惠山铜矿隔江相望。通过对该矿点地表槽探揭露,针对Au、Ag、Cu、Pb、Sb、Bi等指示金矿床化探异常开展激电物探工作,根据深部高极化率异常推测为富含金属矿物的硫化物集合体,结合锆石定年[(128±2)Ma、(129±2)Ma]、围岩岩石地球化学(钙碱性喷出岩和浅成侵入岩)等特征,认为该金矿为与晚侏罗纪太平洋板块俯冲有关的浅层低温高硫化型金矿。
英文摘要:
      The Shiqidaogou gold deposit is located 30 kilometers west of Changbai County, Linjiang City, Jilin Province, and it is separated with the Huishan copper mine that is the largest copper mine in Asia. It is great significance to study the genesis, metallogenic regularity and prospecting criteria of this gold deposit. By carrying out the surface trench exploration and IP geophysical exploration in the anomaly area of Au, Ag, Cu, Pb, Sb and Bi, the deep high polarization anomalies suggest that this area is a sulphide aggregate with rich metal minerals. With the characteristics of zircon dating(128+2)Ma, (129+2)Ma, rock geochemistry of wall rock (calc-alkaline eruptive rock and hypabyssal intrusive rock), it is considered that this gold deposit is related to the subduction of the late Jurassic Pacific plate.
