Abstract

Abstract

Geophysical prospecting is one of the important exploration methods tofind groundwater. Based on the investigation of regional hydrogeological conditions, the authors mainly used the audio-frequency magnetotelluric sounding and high density resistivity to detect the location, depth, scale and occurrence of the deep water-bearing fault in the Rongmu granite area, Qiongzhong County, Hainan Province. The water-bearing fracture zone shows the groove- or strip-shape low resistance anomaly , and can be identified its aquifer position according to its IP half decay time (Th), deviation degree (r) and apparent resistivity (ρs). The hydrogeological drilling revealed the aquifer location to be basically consistent with the result of geophysical interpretation, which proves that the above comprehensive method can be used to accurately determine the location and depth of water-bearing structures. The comprehensive geophysical exploration provides both effective technical support for borehole location design of hydrogeological drilling and useful experience for future groundwater exploration in other similar areas.
