Abstract: In order to identify the geothermal resource endowment in the eastern margin of the Jinzhong Basin, the present paper analyzes the geological and geophysical background data in the area and arranges three geomagnetic (MT) survey lines. Through the collection of field data and its comprehensive interpretation, the spatial distribution characteristics of the resistivity of the geologic bodies in the study area at a depth of 3, 000 m were obtained. The analysis yielded a low-resistance distribution zone exhibiting good continuity within the study area. It was deduced that a primary control fracture, designated F₁, has developed along the periphery of the basin, functioning as a conduit for water conduction and storage. A detailed error analysis of the column results of FC-01 borehole and the interpretation results of MT-2 survey line in the study area reveals an error of approximately 10 m in the interpretation of the top interface of Ordovician system and an error of about 158 m in the interpretation of the bottom interface of Triassic system. A comprehensive analysis reveals that the F₁ fault exhibits a morphology of steep up and slow down, consistent with the characteristics of a "shovel-type positive fault." The upper plate has been identified as a high geothermal resource endowment area, making it a prime location for geothermal resource development. The upper plate of the fault has been identified as a high potential area for geothermal resources, and the findings of the study indicate that the eastern margin of the Jinzhong Basin exhibits a comprehensive geothermal system comprising four components: "cover, thermal storage, storage and transportation channels, and heat source." The presence of notable middle-deep geothermal resource potential is identified. The results of the study provide a geological basis for the quantitative assessment and the comprehensive utilization of geothermal resources in the Jinzhong Basin.
