时间域激发极化法在内蒙古小牛群铜多金属矿的应用

隐伏矿床由于埋藏深度大,地下地质构造特征复杂,因此隐伏矿床的勘查不仅需要地质成矿理论的指导,还需要地球物理技术获得矿体的深部异常信息。本文介绍了激电中梯和激电测深在内蒙古小牛群铜多金属矿区的应用,激电中梯扫面可以快速高效的发现和圈定矿致异常,激电测深可以确定矿体的埋深和空间赋存状态。通过地质资料和钻孔查证,发现本地区中高极化率异常与铜多金属矿有良好的空间对应关系,为进一步在本地区进行铜多金属矿体的勘查提供参考和指导。

Application of the time domain induced polarization method to a copper polymetallic deposit prospecting in Xiaoniuqun area, Inner Mongolia

Concealed deposits are usually buried deeply with complex characteristics of underground geological structure, thus prospecting concealed deposits depends on the guidance of metallogenic theories as well as the deep deposit anomaly information derived from geophysical exploration.In this day and age prospecting concealed deposits is one of significant tasks of geologists. This paper presents the application of IP intermediate gradient and IP sounding to a copper polymetallic deposit in Xiaoniuqun area, Inner Mongolia. IP intermediate gradient can quickly identify and delineate the ore-caused anomalies, IP sounding can determined the depth and spatial occurrence of ore bodies. By geological and drilling data, Wefind high polarizability anomaly has good spatial correspondence with copper polymetallic deposits in this area, providing reference and guidance for further exploration of copper polymetallic deposits in this area.
