| 摘 要： | 地质、土壤地球化学找矿信息、高精度磁测和γ能谱信息的分析表明,乌拉嘎金矿外围土壤地球化学找矿信息特征为Au、As、Sb、Cu、Ag、Mo元素的组合异常。采用综合地质累积指数对研究区内的元素组合异常进行评价,结果表明该方法可以有效地区分异常下限、划分异常等级。按照综合地质累积指数大于零的原则,圈定了研究区内A、B、C三处找矿靶区。

| Abstract: | On the basis of analyzing geology,soil-geochemical prospecting information,high-accuracy magnetic information and ground gamma-ray,the characters of the soil-geochemical prospecting show a composite anomaly on Au,As,Sb,Cu,Ag and Mo.The authors applied the IGEO method to evaluate the prospecting information. The resultsshow that the method is efficient to distinguish anomaly threshold and define the rank of anomaly.According to the principle that the value of IGEO is more than zero,three prospecting target areas A,B and C are delineated in the studied area. |
