江西乐平涌山地区土壤异常特征及找矿前景
|
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.
