汉中盆地及邻区地壳结构和地震活动性研究

    通讯作者: 储日升, chur@asch.whigg.ac.cn
摘要: 本文基于背景噪声成像、多频接收函数和面波联合反演以及莫霍面Ps震相时深转换方法反演了汉中盆地及其邻区的地壳S波速度和厚度,并进一步对比分析了研究区深部结构与地震活动性之间的关系。结果表明:汉中盆地不同区域的浅表沉积厚度和速度存在差异;研究区部分区域莫霍面处的速度变化平缓,Ps震相与P震相的振幅比<0.2;汉中盆地内部鲜有地震发生,其周边10 km范围内地震分布主要受到断层约束;4—16 km震源深度上下界面的分布对应于低速体底层和高速体顶层。本文获得的非均匀分布的沉积厚度、渐变的壳幔过渡带结构与汉中盆地长期以来处于秦岭构造带、大巴山褶皱带以及青藏地块交界区的三联点构造位置密切相关。
