Electrical properties of bedrock fissure water in metamorphic rock area of Fuping County

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.
