地球的层圈结构、力学性质和地幔矿物的高压相变

The layered structure, mechanical properties and high pressure phases change of the earth′s mantle

摘要: 简要介绍了目前被广泛采用的地球内部的分层结构，并说明了板块构造体系中岩石圈和软流层所对应的分层方法，以及各层圈的主要物质成分组成.较系统地介绍了地幔矿物的高压相变实验结果和地幔的矿物组成.结合高温高压下矿物的流变实验，讨论了岩石圈、上地幔、过渡带和下地幔的变形机制和流变学性质.

Abstract: The layered structure of the Earth&apos;s interior and the classification of the lithosphere and asthenosphere as well as the material composition of the layers are described. We review the results of experiments on high pressure phase changes of the mantle and the latter′s mineral composition. The rheological properties of the lithosphere, upper mantle, transient zone and lower mantle are discussed.
