The Application of Comprehensive Geophysical Prospecting Methods in Tangtou Geothermal Exploration, Shanxi Province

Abstract

Tangtou hot spring is a typical geothermal manifestation in Hunyuan County, Shanxi Province. Tangtou area is located in the intersection part of Mount Heng uplift zone and Tanghe fault zone. The reservoir is structural fracture type. Comprehensive geophysical prospecting methods are applied in geothermal exploration to identify the geological condition. Based on geological, hydrogeological data, the methods of gravity, magnetic and CSAMT are implemented in this geothermal exploration. The research indicates that Tangtou area exists two faults, NW and NS direction, which control the distribution of hot spring. The paper discusses the prospect of geothermal resources exploration and provides the basis for further utilization.
