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 2D 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.
