摘　　要：乐平涌山地区隶属于钦杭成矿带东段塔前—赋春铜多金属成矿带。在该地区开展1∶1万土壤地球化学测量工作,分析元素地球化学特征、单元素异常特征、元素组合特征及结合成矿地质背景,共圈定18处综合异常,通过对综合异常进行分类评价及评序,优选出较好的3处异常开展异常详细查证工作。经地表探槽揭露,新发现金矿(化)点2处,揭露金矿体2条,金矿化体2条,取得较好的找矿效果,认为该区找矿前景良好,是寻找矽卡岩型铜矿、韧性剪切型金矿的有利地区。The Yongshan area of Leping City belongs to the front of the tower in the east section of the Qinhang metallogenic belt-Fuchun copper polymetallic ore-forming belt. Based on 1∶10,000 soil geochemical survey in this area, the authors analyzed elemental geochemical characteristics, single element anomaly characteristics and elemental combination characteristics. In combination with the geological background of mineralization, a total of 18 comprehensive anomalies were identified, and the comprehensive anomalies were classified and evaluated. Preferably, 3 better anomalies were verified in detail. The surface exploration trough revealed 2 new gold (chemical) sites, 2 gold orebodies and 2 gold mineralized bodies, thus obtaining a good ore prospecting effect. It is believed that the ore-search prospects in the area are good, and a skarn-type copper deposit is expected to be found. This area is the favorable area for finding ductile shear gold deposit.
