摘要
简要介绍了瞬变电磁法原理和特点、WDC— 2B型瞬变电磁勘探系统及其野外工作方法。在充分考虑富盛铅锌矿地质矿产和物性特征的基础上 ,重点应用重叠回线装置 ,研究已知矿体上方的瞬变电磁响应特征及其与地质矿产的联系 ,提出了在富盛铅锌矿地质物性条件下 ,瞬变电磁响应模式为“上凹下凸” ,同时对矿区外围发现的瞬变电磁响应异常 ,结合矿区的地质物性资料进行了初步解释。
The principle and characteristics of instant electromagnetic method, WDC 2B instant electromagnetic exploration system and its field method are briefly introduced in this paper. According to the characteristics of geology, mineral resources and material quality of Fusheng Pb Zn deposit, we mainly apply superimposed loop equipment to studying the instant electromagnetic response characteristics and their connection with geology and mineral resources. The instant electromagnetic response model is “upper concave and lower convex”under the condition of the geology and material quality of this deposit. And a preliminary interpretation of the instant electromagnetic response anomaly discovered outside the ore field is proposed in combination with the geology and material quality of ore field.
