| Abstract | Resistivity, magnetic and seismic surveys were carried out in the Pong Kum hot spring area in Chiang Mai, northern Thailand. The resistivity survey was conducted using dipole-dipole configuration with an electrode separation of 15 m. Interpretation of resistivity data using model curves indicated low resistivity zones (geothermal anomaly) representing the basement geothermal reservoirs. This target exploration zone is located about 150 m southwest of the hot spring surface and is approximately 80 m deep. Results from 2D seismic profiles indicated a shallow basement and fault zone near the surface of the hot spring. 2D total-field magnetic data show a low magnetic susceptibility zone in the NE-SW trending fault, which may represent channels for up-flowing geothermal water. |
