吉林省延吉市石人村调查区地质特征及金找矿前景分析

Analysis on geological features and gold prospecting prospect of Shirencun exploration area in Yanji City,Jilin Province

石人村地处延边中生代金、多金属成矿带西段,区域成矿地质条件优越。利用地物化勘查方法大致查明了调查区内地层、岩浆岩、构造等基础地质特征,分析了区域成矿地质背景,并圈定出8条含金蚀变带、4条金矿体。石人村地区具有明显的物化探异常,显示了良好的找矿前景。

Shirencun is located in the western part of the Mesozoic gold polymetallic metallogenic belt in Yanbian,with favorable regional metallogenic geological conditions.The basic geological features of strata,magmatic rocks and structures in the exploration area are roughly identified by using geophysical and geochemical exploration methods.The regional metallogenic geological background is analyzed,and eight gold bearing alteration zones and four gold ore bodies are delineated.There are obvious geophysical and geochemical anomalies in the Shirencun exploration area,which shows a good prospecting prospect.
