天山及其邻区板块构造演化与岩石层动力学问题探讨
DISCUSSION OF SOME PROBLEMS OF PLATE TECTONICS EVOLUTION AND MANTLE DYNAMICS OF TIANSHAN AND ITS ADJACENT AREA
【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。
【Abstract】 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.
