渤海湾盆地新生代以来构造-热演化模拟研究
发布时间:2021-07-10 06:57
渤海湾盆地是华北最大的新生代裂谷盆地,具有最完整的新生代地层记录,是研究盆地演化的理想区域.本文基于二维多期拉张模型,对渤海湾盆地内9条地震解释剖面进行新生代构造-热演化模拟,以揭示盆地拉张强度及热演化的时空差异性,为探讨盆地演化的地球动力学机制提供依据.研究结果表明:渤海湾盆地各坳陷新生代期间的总拉张系数为1.28~2.39,渤中坳陷和辽东湾坳陷的总拉张系数最大,而辽河坳陷和临清坳陷的拉张系数最小.盆地基底热流在古近纪中、晚期达到峰值71~100mW·m-2,之后逐渐降低至现今.盆地西部热流峰期出现的时间早于东部.由盆地拉张系数和基底热流的研究结果得出,渤海湾盆地新生代的拉张有着自西向东,自南向北的迁移,与沉积、沉降中心的迁移方向一致.太平洋板片新生代期间的幕式向东后撤可能是造成渤海湾盆地幕式拉张及拉张中心向东迁移的主要动力学机制.
