Ground Penetrating Radar (GPR) has the ability to map subsurface geological structures and detect variations in moisture that could help understand geothermal exploration. However, GPR is limited to shallow depths of less than 50 meters, where most geothermal reservoirs are located. This study uses GPR data from Beijing to create digital models of the subsurface and identify potential geothermal indicators like quartz sinters. The results demonstrate GPR's capability to detect geochemical markers associated with geothermal activity and map prospective geothermal reservoir locations. While GPR has limitations for deep exploration, it shows potential as a new efficient tool for initial geothermal prospecting.
