摘要
近几年,为配合深部找矿工作,在胶东地区开展了大量的物探工作,取得了明显的探测效果。焦家—仓上地区虽开展过大量钻探工作,并对地壳深部进行揭露,但覆盖面小,无法全面掌握地质信息。在前人成果的基础上,进一步开展了高精度重力剖面、高精度磁法剖面、MT重磁电联合反演、CSAMT、二维地震等综合物探工作,通过对所得结果互相验证并结合钻探揭露,较全面地提取了焦家—仓上地区深部地质、构造等信息,构建了三维地质模型,确定了深部找矿靶区,为下一步深部找矿工作提供了方向及可靠依据。
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.
