    Tectonic Relationship between Upper and Lower Lithosphere in Guangxi Area: A Comprehension from Lithospheric Density and Magnetic Structures

    • 摘要: 广西地处华南地块、印支地块与西太平洋板块的汇合部位,因特殊的构造部位,广西区内大地构造单元归属、构造单元边界等许多基础地质问题一直存在争议.自新生代以来的板块构造运动对岩石圈的改造,广西地壳与上地幔在地震波速度及温度结构方面具有显著差异.应用卫星重、磁异常数据以及区域重力和航磁资料对广西地区岩石圈密度和磁化率结构及其与上地壳构造的关系开展了研究,结果显示广西地区地壳密度和上地壳磁性结构与现今地表构造较为契合,但下地壳密度结构与上地幔存在不连续现象;此外,岩石圈磁化率结构指示中下地壳存在不同范围和程度的解耦.对广西岩石圈密度与磁性结构的解读认为,在中生代以来岩石圈被大规模改造的背景下,幔源物质上侵至上地壳的规模和范围都有限,这可能是整个广西地区上地幔结构与地壳构造不对应的主要原因.
