P_2, the stage in which Meso-Tethys ( Paleo-South China Sea) began to open and the Paleo-Tethys to subduct; P2,中特提斯(古南海)开始出现、古特提斯开始消减阶段;
An important Problem was how continent crust subduct and exhumate. ( 2) P_2, the stage in which Meso-Tethys ( Paleo-South China Sea) began to open and the Paleo-Tethys to subduct; 在超高压变质带的研究中最受关注的问题是大陆壳如何被俯冲到地幔的深度义返回地表的。(2)P2,中特提斯(古南海)开始出现、古特提斯开始消减阶段;
Mineralogical evidences indicate that the continental crust rocks with low density could subduct down to depth of> 200 km and undergo UHPM; 通过细致的矿物学研究,确认低密度的陆壳岩石可以被俯冲到地下200多公里深处,经历超高压变质作用;
We speculate that the northwest Pacific slab subduct across the middle transition zone beneath Kuril Islands, then just arrive at the lower transition zone beneath North-East China. 本文推测西北太平洋板片横穿过千岛群岛锡霍特山脉下方过渡带中部,前缘部分可能刚抵达我国东北过渡带的底部。
High velocity anomalies in the Indian Plate and low velocity anomalies in the Tibetan region are discontinuous at the collision region in the east-west direction, which suggests that the Indian Plate may subduct in different blocks. 而印度板块的高速及青藏高原内部的低速区,在东西方向上有一定的不连续性,表明印度板块很可能不是以一个整体运动,而是分块以不同的速率及方向运动。
