Application of Apparent Resistivity Intermediate Gradient and Depth Sounding in Prospecting for Vein Quartz

脉石英相对于围岩物性特征较为独特,呈高阻特征。依据其物性条件进行了视电阻率中梯及测深工作,详细分析了脉石英在激电中梯视电阻率等值线图上的平面分布情况,以及在激电测深视电阻率断面图上的空间展布特征。结合已有地质资料和槽探结果,总结了寻找脉石英的有效物探方法,值得今后借鉴使用。

Compared with the surrounding rock,the vein quartz ore is quite unique in physical properties,showing high resistance characteristics.In this paper,the IP intermediate gradient and depth sounding work is carried out according to its physical conditions,and the planar distribution of vein quartz ore on the contour map of the apparent resistivity in the IP intermediate gradient is analyzed in detail,as well as the apparent resistivity in the IP sounding.The spatial distribution characteristics on the crosssectional view.Combining existing geological data and trenching results,a set of effective geophysical methods for finding vein quartz deposits is summarized,which is worthy of reference in the future.
