摘要
着重介绍了上地幔各向异性及其成因,研究内容和方法,各向异性研究的地球动力学意义,并强调指出橄榄石和辉石在塑性固态流动过程中产生的晶格优选方位或组构是导致上地幔各向异性最主要原因。
The aims of this paper are to present a review of anisotropy of the upper mantle and its genesis, the contents and methods of the research and the implications of the research for geodynamics. It is emphasised that the lattice-preferred orientation (fabric)of olivine and pyroxene induced by plastic flow is the main cause for anisotropy of the upper mantle.
