Abstract

Abstract

Geothermal energy mainly migrates and accumulates along fractured zones. Ascertaining the faults in the study area is an important goal of geothermal exploration. Many faults are distributed in the Zhangye-Minle basin. They are deeply buried and are difficult to find on the surface. The special geological conditions make it difficult to fully utilize the advantages of conventional geophysical methods. By contrast, the activated charcoal radon measurement features strong anti-interference, large detection depth, and low cost, which are unique advantages in detecting concealed structures. This study investigated the concealed structures in the Zhangye-Minle basin using the activated charcoal radon measurement. Through the trend analysis of measured radon concentrations, this study extracted local anomalies and determined the favorable parts for the geothermal water exploration in the study area, creating conditions for further drilling and shallow artificial seismic exploration.
