摘　　要：为了解吴川-四会断裂带北段金找矿前景,通过对该地区开展的1:5万水系沉积物测量数据(-60目粒级)进行分析,对该区的元素含量及分布、综合异常特征、元素相关性及异常元素组合等特征进行研究,在区内圈定金综合异常6处,发现区内Au、As、Ag、Sb、Pb、Hg的异常规模大,异常多分布在断裂构造中,地质及地球化学条件优越,具有较大的成矿潜力。圈定了威井找矿靶区,查证后发现南坑金矿点,该矿点找矿潜力较好,有望找到大-中型金银矿床。In order to understand the prospect of gold exploration in the northern section of the Wuchuan Sihui fault zone,the 1:50000 water system sediment measurement data (-60 mesh particle size) conducted in the area were analyzed.The element content and distribution,comprehensive anomaly characteristics,element correlation,and abnormal element combination of the area were studied.Six comprehensive deposit anomalies were found in the inner circle of the area,and it was found that the anomalies of Au,As,Ag,Sb,Pb,and Hg were large in scale and mostly distributed in the fault structures.The geological and geochemical conditions were superior,and it had great mineralization potential.We have delineated the target area for mineral exploration in Weijing and discovered the Nankeng gold deposit after verification.This deposit has good potential for mineral exploration and is expected to find large to medium-sized gold and silver deposits.
