中文摘要：
作为喜马拉雅造山带变质核的高喜马拉雅杂岩带，是以高级变质岩石、普遍的深熔反应以及高温韧性变形为主要特征的热碰撞造山带。在高喜马拉雅平行造山的韧性伸展构造发现的基础上，建立高喜马拉雅挤出的3-D构造模式，并提出了挤出的动力学过程：（1）造成高喜马拉雅中弱和热物质产生的局部熔融阶段（46~35Ma），（2）平行造山的韧性伸展和重力裂陷阶段（28～26Ma开始），（3）韧性逆冲型剪切带形成阶段（〉626-23Ma），（4）MCT和STD的形成造成的高喜马拉雅挤出阶段（23~17Ma）。
英文摘要：
The Greater Himalayan Complex （GHC） , as the metamorphic core of the Himalayan orogen, shows a ＂hot＂ coUisional orogen characterized by high-grade （up to granulite facies） metamorphic rocks exhumed from the middle-lower crust, widespread migmatites from extensive anatectic processes and high-temperature ductile deformation. A three-dimensional tectonic model for extrusion of the GHC has been proposed based on the discovery of widespread orogen-parallel ductile extension. It is suggested that extrusion dynamic processes of the GHC are as follows： （1） partial melting in 45-36Ma resulting in the weak and hot middle crust, （2） orogenparallel gravitational collapse in 28-26Ma, （3） ductile thrusting since 〉 26 Ma and （4） ductile extrusion resulting from the formation of MCT and STD during 23-17Ma.
