激发极化法探测泰山群变质岩地下水

Groundwater detection in metamorphic rock of Taishan group with applying induced polarization method

文章阐述了激发极化法的基本原理和技术方法,利用激发激化法的衰减度、半衰时、充电率等激电参数,探讨了变质岩地区含水层辨认、含水层埋深确定、矿体干扰异常等规律。该方法受地形影响小,曲线反映异常直观,解释方便,完成了在泰山群变质岩地区找水的任务。

Having elaborated the basic principle and methodology of induced polarization, this paper demonstrated several practical skills in water-bearing stratum exploration in the Taishan group metamorphic rock with applying induced polarization parameters including the decline degree, the half-decline time, the charging rate and so forth, for instance, to identify the boundary of water-bearing stratum, to determinate the depth of burying stratum, to describe the abnormal distribution of stratum induced ore body intrusion, etc. It was suggested that induced polarization method was slightly affected by the topographic, while production curve could straight reflect abnormal distribution of water-bearing stratum and became easy to interpret observed phenomena.
