| 摘 要： | 黑龙江鸡东金场沟铜钼金及多金属矿化集中区是与中生代火山--次火山活动有关的矿区之一。研究表明,低电阻率(450Ω·m)与高极化率(5%)可作为重要的地球物理找矿间接标志;Cu、Au、Mo、Ag等元素异常可作为重要的地球化学找矿间接标志。经对该区的地球物理与地球化学的特征分析,结合研究区地质条件,利用相似类比的方法进行找矿靶区的预测,成功地找到矿体。

| Abstract: | Jinchanggou copper-molybdenum-gold and polymetallic mineralization concentrating area in Jidong of Heilongjiang is a mining area related to Mesoaoic volcano-inferior volcanic activities. The study shows low resistivity （ 〈450 Ω·m） and high polarizability （ 〉5% ） can be regarded as indirect signs of geophysical prospecting,while the anomaly elements of Cu,Au,Mo,Ag can be used as indirect signs of geochemical prospecting. Based on the analysis of geophysical and geochemical characteristics,combining with geological conditions,the authors utilizing analogical method to forecast prospecting target,and discovered the ore body successfully in studied area. |
