太行山缺水地区变质岩裂隙水水文地质特征与其电性响应之间关系的研究是长期困扰地质学者的一个大难题。阜平县变质岩地区是典型的缺水地区,根据区域地质资料,进行了阜平县变质岩地区水文地质研究,查明了该地区的地层、地质构造和变质岩裂隙水的赋存规律。在此基础上,采用音频大地电场法、放射性法、音频大地电磁法和激电法对比研究了变质岩裂隙水水文地质特征的电性响应,并布置地质钻孔验证了水文地质特征与电性响应之间的对应程度。结果表明,阜平县变质岩裂隙水地区水文地质特征与其电性响应之间具有明显的一一对应关系。阜平县变质岩基岩裂隙水地区的地下水勘查具有很强的实践意义,为此类变质岩分布区地下水的找寻起到了示范作用。

[Abstract]
The relationship between the hydrogeological properties and electrical responses of metamorphic rock fissure water in water-shortage areas of Taihang Mountains has perplexed geologists for a long time. The metamorphic rock area in Fuping County is a typical water-shortage area. Based on the regional geological data, we studied the hydrogeological properties of the metamorphic rock area in Fuping County. We found out the occurrence patterns of the strata, geological structure, and metamorphic rock fissure water. On this basis, we studied the electrical responses to the hydrogeological properties of metamorphic rock fissure water using audio frequency telluric electricity field method, radioactivity exploration, audio frequency magnetotelluric method, and induced polarization method. Geological drills were arranged to test and verify the degree of correspondence between the hydrogeological properties and electrical responses. The results showed that there is evident one-to-one correspondence between the hydrogeological properties and electrical responses of the metamorphic rock fissure water in Fuping County. The groundwater exploration in the metamorphic rock fissure water area in Fuping County has huge practical significance, and it will serve as an example for finding groundwater in other metamorphic rock areas of this type.
