Our new model suggests that Indian plate has subducted with different north reach from the west to east beneath the Tibetan Plateau, and the Pacific plate has subducted down to the depth of transition zone and stagnates in the transition zone in East China. 新模型表明印度岩石圈俯冲到青藏高原之下,并且在青藏高原下自西向东具有不同的北部边缘,我们同时看到西太平洋俯冲到欧亚板块之下并滞留在地幔过渡带中。
