| 摘 要： | 当代造山带研究正从以往以阐明板块运动历史和板块边界相互作用为主，转向并进入到了阐明造山带岩石圈及其之下地幔系统中各层圈相互作用过程和动力学的新阶段，大陆动力学正成为造山带研究的主要指导思想。在这种形势下，造山带研究正围绕着下列前沿问题展开工作：（１）碰撞后的造山过程：拆沉作用、伸展垮塌和深变质岩剥露；（２）造山带之下地幔的结构和演化；（３）壳内软层的性质和动力学作用；（４）造山带地壳的精细构造和演化；（５）巨量花岗岩的成因和侵位动力学；（６）沉积作用与造山过程：根据沉积特征对造山过程、造山事件的恢复再造；（７）新元古代超大陆。

| Abstract: | The geological sciences are entering a new period for the foundation of earthsystem science,and the orogenic beIt studies will play an important role in the establish-ment of new knowledge.Continental dynamics is the key idea directing the current and fu-ture researches of the orogenic belts. The emphasis of the orogenic belt study will be puton elucidating the dynamics of lithosphere and the interactions among the different layersin crust-mantle system. Therefore, the current research work of the orogenic belt is beingcarried out around the following aspects:(1)postorogenic processes;(2) rheology in thecrust:(3)three dimensional lithospheric structures:(4)relationships between the earthsurface and mantle;(5)origin of vast-volume grantic rocks:(6)late-proterozoic super-continents:(7)evolution of the foreland basins. |
