| 中文摘要: |
| 大别山北麓山店地区发现的斑岩型铜钼矿床均为隐伏矿床，在地质勘探过程中采用土壤地球化学测量方法，查明地球化学晕指示元素为金、银、铜、铜、锌、钨、锡、钼、砷、锑、铋，结合地球化学异常选定勘查靶区；综合研究元素组合的前缘晕、近矿晕和尾晕及各元素的叠合情况，判断是否为矿致异常及矿体赋存部位。实践证明，运用地球化学方法预测隐伏铜钼矿床是一种经济有效的找矿方法，采用地球化学资料和地质资料相结合，可有效地判断地质体的含矿性，确定有利的成矿部位。 |
| 英文摘要: |
| The porphyry copper-molybdenum deposits discovered at north Dabieshan mountain area in Henan Province are concealed ones. During prospecting geochemical method-soil geochemical survey is used and indicators of geochemical halo elements Au,Ag,Cu,Pb,Zn,W,Sn,Mo,As,Sb,Bi are determined. According to anomlies lineated with the elements prospecting targets are located. Results of comprehensive study of front margin halo, near ore halo and superimposition of each element are used to judge the anomly which is caused by ore and the position where ore body occurs. The prospecting practice shows that geochemical method is an effective and economic tool to predict blind Cu-Mo deposit. Combined with geological data geochemical data can be used to judge effectively ore-bearing property of a geological body and determine the proper position of ore body. |
