Deep lithospheric mantle in the Qinghai-Tibetan plateau and adjacent area, which consists of imbricated dipping-northward multi-lithospheric terrains, is in convergent-subduction regime for sinking of cold lithospheric material. Geoidal anomalies and P/S velocity tomographies show that subduction into beneath Euro-Asian continent by Indian lithosphere not only causes intensive crustal upwelling, thickening and shorting deformation along S-N, but also affects depth of～600km in the plateau and eastern part of the Chinese continent and southern margin of the Siberian block.

大地水准面异常和P/S速度层析成像显示，印度大陆岩石圈向欧亚大陆的俯冲作用，不只是引起地壳的强烈加厚、隆升和南北向缩短变形，纵向上影响到600km深度，横向上波及到了中国东部和西伯利亚南部。
