Application of Audio-frequency Magnetotelluric Method and Radon Testing in a Certain Geothermal Investagation
In recent years,audio-frequency magnetotelluric(AMT)method and soil radon testing have achieved excellent exploration results in the field of large-deepth geological and regional tectonic investi-gation.This paper introduces a comprehensive application of these two methods to detect a geothermal structure in western Sichuan Province.Through data processing and interpretation,comprehensive analy-sis and judegment,the geothermal distribution in the magmatic rock area is identified.After drilling veri-fication,geothermal water is successfully mined.Practice has shown that audio-frequency magnetotelluric method and radon testing method have high practical and popularization value in geothermal exploration.
