吉林省和龙市土山子地区地质特征及找矿靶区选择

Geological features and selection of prospecting targets of Tushanzi area in Helong City,Jilin Province

土山子地区位于夹皮沟—金城洞金、多金属成矿带东部,该成矿带是吉林省重要的金及多金属找矿远景区。成矿带内现已发现的金、多金属矿(床)点众多,根据已知的矿(化)点、矿化线索及近期野外地质调查工作,结合同一成矿带内松江河金矿、海沟金矿、旭阳金矿、金城洞金矿、厚底洞金矿等矿床的地质特征及物化探异常特征,该地区内初步确定两个找矿靶区。

Tushanzi area is located in the east of Jiapigou-Jinchengdong gold and polymetallic metallogenic belt,which is an important gold and polymetallic prospecting area in Jilin Province. There are many gold and polymetallic deposits found in the metallogenic belt. According to the known ore( chemical) points,mineralization clues and recent field geological investigation,combined with the geological features of Songjiang gold deposit,Haigou gold deposit,Xuyang gold deposit,Jinchengdong gold deposit,Houdidong gold deposit and other deposits in the same metallogenic belt,and the characteristics of geophysical and geochemical anomalies,two prospecting targets in this area have been preliminarily determined.
