| 中文摘要: |
| 复电阻率(CR)法是基于位场理论的一种地面勘探方法,是以岩矿石的频谱或时谱特性差异为研究基础。文章介绍了那吉河铅锌矿勘查区域的地质概况和地球物理特征,详细分析了CR法在NJH-CR2线勘查中所获得的电性参数即导电性和极化性特征,据CR法的探测结果并且结合区内地层分布、成矿条件和已知钻孔的岩矿石的物性资料,总结了该地区铅锌银矿体的异常特征:高ms、高τs、低ρs、低Cs,即“二高二低”组合特征。 |
| 英文摘要: |
| The complex resistivity method (CR) is a kind of ground geophysical exploration approach based on potential field theory, which is based on differences of spectral properties of rocks and minerals. This paper firstly introduced the geological and geophysical characteristics of the Najihe lead-zinc deposit, then described the specific application of complex resistivity method in the exploration area located in NJH-CR2 line. By analyzing the electrical conductivity and polarization characteristics in detail by CR method, in combination of stratigraphic distribution, metallogenic geological conditions and physical properties of rocks and minerals from known drillholes, the features of CR anomalies were summarized, i.e. high ms, highτs,low ρs and lowCs. |
