摘　　要：良坑钼钨矿区位于赣东北断裂带南东侧、钦杭成矿带北部多金属成矿带内,成矿地质条件优越。文章研究良坑钼钨矿区的地质特征,分析该矿区的土壤地球化学异常,结合地形、地质及矿化特征等,共圈定6个综合异常。优选3个最有利的综合异常进行工程验证,发现数条钼矿体和钨矿体,取得了较好的找矿效果,拓展了赣东北断裂带南东侧找矿新领域,表明土壤地球化学测量在良坑钼钨矿区勘查中具有较好的应用效果,对赣东北断裂两侧进一步找矿具有一定参考。Liangkeng Mo-W ore district is located in the southeast of the fault belt in northeastern Jiangxi and within the poly-metallic metallogenic belt of the northern Qin-Hang mineralization belt.It has an excellent metallogenic condition.Based on the geological characteristics of the Liangkeng Mo-W deposit including geomorphology,geology and mineralization,this paper defines six integrated anomalous areas using the soil geochemical anomalies.The three advantageous anomalous areas were selected to carry out engineering testing,and several Mo-bearing ore bodies and W-bearing ore bodies have been found.Promising exploration results have been obtained,and this will expand a new field for prospecting in the southeastern part of the fault belt.Therefore,this study shows that soil geochemical measurement has significant application effects in the prospecting of the Liangkeng Mo-W ore district and will provide some references for future prospecting on the both sides of the fault belt in northeastern Jiangxi Province.
