Geothermal resources is a green and renewable energy that is widespread distributed in the earth. Geothermal is one of the noteworthy alternative resource to achieve the targets of China's Carbon Emissions Peak by 2030 and Carbon Neutrality by 2060. In order to strengthen Shenzhen taking the lead in building a demonstration zone as an example for Low-Carbon city nationwide and worldwide, we utilize wide-field electromagnetic method (WFEM) for mapping the resistivity structures in the Shenzhen International Low Carbon City (ILCC). We have also analysed the resistivity for 66 representative rock samples, which are helping us better comprehend the WFEM results and identify the buried structures. The resistivity result shows the rocks are a negative flower structure with concave-up faults at ILCC, which indicate there have a good heat conducted structure. From the resistivity result, we infer there is a high potential geothermal resources of the north ILCC.
