摘　　要：小岭子地处北西西向辉发河—金城洞大断裂与北东向两江—春阳深断裂的交汇处,区域成矿地质条件优越。利用地、物、化勘查方法大致查明了勘查区内地层、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13条含金蚀变带和10条金矿体。小岭子位于吉林省著名的夹皮沟—金城洞成矿带上,具有非常好的找矿前景。Xiaolingzi is located in the intersection of the NWW trending Huifahe-Jinchengdong fault and the NE trending Liangjiang-Chunyang deep fault.The regional metallogenic geological conditions are superior.The basic geological characteristics of strata,magmatic rocks and structures in the investigation area are roughly identified by using geological,geophysical and geochemical exploration methods.The regional metallogenic geological background is analyzed,and 13 gold-bearing alteration zones and 10 gold ore bodies are delineated.Xiaolingzi is located in the famous Jiapigou-Jinchengdong metallogenic belt in Jilin Province,which has a very good prospecting prospect.
