Abstract
This research is to present the model to explore the hot spring by measuring the electrical resistivity of geological 3D model with offset Pole - Dipole array at Ban-Punamron, Dan-Chang district, Suphan-Buri province, Thailand. This survey was covered area of 1.60 x 1.60 square kilometer with current electrode and potential electrode, and the distance between them are 100 -m, inside survey area. The outside survey area has source line between them are 200 -m. The result showed that the 3D geological structures of the survey area which found at mountains have high resistivity zones which more than 3,500 ohm•m as corresponding to granite, quartz and feldspar outcrop at that location. At middle of the survey area has resistivity of 30 - 500 ohm•m. They are represented to the position of groundwater, sludge, faults and weathered layer. Study result indicate geological structure of this hot spring is identified as hot spring type 2 which classified based on general hot spring model that found in Thailand. The hot fluid uprise along faults, mixed with cool ground water and become equilibrium with host rock. However, these interpretation results indicated that the 3D modeling of hot-spring which are accurate and reflect geological conditions better than the traditional survey.
