摘要
综合构造地质学、固体地球物理学、岩石地球化学、地震层析成像数据和板块构造演化的历史进程,探讨了天山地区板块运动与地幔热演化动力学过程,并尝试用新的"W型对流-俯冲挤出"模式解释天山地区复杂的陆内造山带的岩石层构造动力学问题。
Integrating structural geology, geophysics, petrology and geochemistry and combining with seismic tomography data for the ancient remnants of the subducted lithosphere slab in the mantle, restoring the historical evolution of plate tectonics, we in-depth have discussed the inner relevance between plate motion and mantle evolution processes of the Tianshan region and mantle evolution, and try to explore new ＂W Convection-Diving out＂ model to explain the complex dynamics of rock within the continental orogenic belt of Tianshan.
