Abstract: In recent years， a large amount of geophysical work has been carried out in the Jiaojia-Cangshang area of the Jiaodong region to support deep exploration and has achieved a prominent effect. Although a significant amount of drilling work has been conducted and deep crustal information has been revealed in the Jiaojia-Cangshang area， the coverage is limited， and a comprehensive understanding of the geological information is lacking. Based on previous research， high-precision gravity profiles， high-precision magnetic profiles， MT gravity-magnetic-electric joint inversion， CSAMT， and 2 D seismic surveys were further conducted to comprehensively understand the deep geological and structural information in the Jiaojia-Cangshang area. These results were validated and combined with drilling data to construct a three-dimensional geological model. Target areas for deep exploration were identified， providing direction and a reliable basis for the next step of deep exploration work.
