Abstract:Two geothermal radon spring wells have been found in Dasunzhuang area in Meigui town in Pingyin county in Ji'nan city. The radon content in geothermal fluid is 332.6~ 625.7Bq/L, which is a rare natural physiotherapy hot mineral water resource. Based on extensive collection of previous research data, its formation mechanism has been studied by means of radon measurement in soil area, radon measurement in soil profile, controllable source audio frequency magnetotelluric method (CSAMT) measurement, and radon measurement in water. By analyzing the material source conditions, spatial conditions and dynamic conditions of radon, combining with geological conditions, hydrogeological conditions, structural conditions and hydrochemical characteristics of geothermal field, the formation mechanism model of Dasunzhuang geothermal radon spring has been established. It will provide some references for the exploration and development of geothermal radon spring in similar geological background conditions.
