Abstract: In order to investigate the deep geothermal structure in Liushan Lake Scenic Area, Sihong County, Jiangsu Province, geological and geophysical data and known exploration borehole data were collected, 14 Audio Magnetotelluric Sounding (AMT) survey lines were laid, and the resistivity distribution of the shallow geological body at 2000 m in the study area was obtained through data acquisition, pre-processing and inversion. The exploration results show that there was a good low resistance distribution zone in the study area with good continuity, and two deep structural fault f₁ and f₂ are inferred. Among them, fault f₂ is presumed to be large in scale and contains water in the fracture zone, while the upper part of the fracture zone is a complete-more complete high-resistance layer, which may be a good cover layer. Therefore, it is speculated that the deep fracture zone f₂ has good water-bearing and storage channels, and it is suggested to focus on the location of the low resistance anomaly in the tectonic zone to provide a basis for the next drilling placement.
