鄂尔多斯地块西缘莫霍面起伏及泊松比分布

open access: yesDizhen xuebao, 2018
收集了鄂尔多斯地块西缘的21个宁夏区域地震台网台站和183个中国地震科学探测台阵台站记录到的2015年1月至2016年1月期间的远震P波资料,通过对其进行反褶积提取接收函数,并利用H-Kappa叠加方法计算了研究区内的莫霍面深度和泊松比。结果表明:研究区的莫霍面深度在36—58 km范围内变化,大体呈南厚北薄、西厚东薄的特点,且具有明显的分区特征,即以香山—天景山断裂为界,莫霍面在南北向呈现明显的起伏变化,该断裂以南的地壳增厚方式可能与青藏高原的水平挤压力所导致的上地壳重叠有关 ...
