地球内部主要层圈相互作用研究的若干进展

20世纪90年代以来，人们正在探索建立一个统一的全球动力学体系及各圈层相互作用的热、物质运动机制。通过对地核、核幔边界、过渡带、岩石圈—软流圈地幔、地幔柱理论、壳幔边界和地壳内热、物质的交换和圈层流变运动方式等进行分析，讨论了地球各圈层之间存在的热与物质的交换机制以及底侵作用、拆沉作用和岩浆部分熔融作用等壳幔相互作用过程。认为壳幔作用过程表现为一种阶段式、递进式动力学和物理化学演化过程。壳幔相互作用不仅是大陆动力学演化的主要机制，而且与深部地幔的交代及上地壳变形、造山带、盆地形成和演化之间存在耦合过程。基于壳幔热和物质相互作用的研究可以对上地幔及更深层次的地质作用过程进行限定。

Progress in Study of Interactions Between Interier Layers of the Earth

Since the last decade of the 20th century, scientists have been trying to establish a globle geody namic system and more understanding the mechanism of heat and material interactions between interier layers of the Earth. This paper presents analyses of core, core mantle boundry, transitional zone of mantle, upper and lower mantle, crust-mantle boundry, plume theory, manterial exchanges and rheological motion in different layers. Heat and material exchanges of interier layers of the Earth and the crust-mantle interaction are dis cussed, including underplating, delamination and partial melting processes. It is concluded that the crust-mantle interaction is a process increasing by degrees dynamically and physical chemically. The crust-mantle interaction is not only a main mechanism of continental dynamics, but also couples with orogene, mantle convection, form and evolution of basin-range system and deform of upper crust. The research could provide constrains on processes of upper mantle and deep Earth.
