| Abstract;The rock salt layers underlie at shallow depth under 50m-100m in depth and saline groundwater is distributed in Phra Yuen area, northeast Thailand. The G1 and F1 faults were inferred by analyses of geological columns at 16 sites (A1-A16) of the regular 1 km grid covered 3km * 3km area and photo-lineaments interpretation. The electromagnetic prospecting, the electric prospecting, and the soil temperature survey at 1 m depth were carried out along the survey lines of A5-A7 and A10-A12 to verify the inferred faults. The conductivity sections by electromagnetic survey showed the vertical distributions of high conductivity zone around the inferred G1 and F1 faults. The resistivity section showed the vertical distributions of high resistivity zone around F1 fault. The results of soil temperature survey revealed an anomaly low soil temperature zone over the F1 fault. The cross-check of different methods of physical prospecting ensures the possibility of inferred G1 and F1 faults. The monitoring result of groundwater showed that the electric conductivity of groundwater changes seasonally and locally. The evidences of groundwater with a high electric conductivity and distribution of ponds with water salinization along inferred faults support that fault has a function of pathway for upward movement of the saline groundwater.
