Abstract:

为了研究青藏高源东北部块体构造变形的深部驱动机制,笔者对青藏高原东北部的天然地震观测数据进行地震层析反演,并结合同一剖面的接收函数及各向异性结果进行讨论。介绍了ACH方法的基本原理,论述了由于印度板块向北俯冲的强大的持续作用力,造就了NE向俯冲到柴达木盆地之下的昆仑造山带,并发现在巴颜喀拉地体下方壳幔内的仰冲活动。壳幔内的低速体十分显著地出现在阿尼玛卿缝合线以北,深度可达300km。推断该低速体可能与昆仑断裂的深层的剪切作用有关。深部资料显示该区莫霍界面由北向南逐渐加深,这与青藏高原东北部的岩石圈减薄现象一致,而且与印度板块向北运动的远程效应有关。另外,地震层析结果及各向异性分析也支持青藏高原东北部主应力方向转为NE向的观点。
