地壳分展模式

本文旨在综合分析早期经典的和近年来提出的陆壳的９种分层模式，既包括地球物理的，也包括构造变形、变质和物质成分的，指明它们之间的联系和区别。结合地质和地球物理的最新进展，本文对这些模式进行了评介，对莫霍面、下地壳组分及反射下地壳的地质意义提出了看法．这些模式，尤其是近年来提出的大陆壳分层的几种模式无疑对地质和地球物理学家进一步认识和了解陆壳的复杂地质作用、地壳和地球的演化及早寒武纪地质是有益的．

MODELS OF CRUSTAL LEVELS

There have some models of crustal levels,including both oceanic and continental ones.Compared with the widely accepted model of oceanic crustal level by composition, continental crust have been diversely divided. By correlating and contrasting every of those, theauthor points out their advantages and disadvantages,and where they can be best-used. ForMohorovicic discontinuity, composition of lower crust, and geologic meaning of reflectivelower crust of the continent, some good ideas based on new progress of geology and geophysics have been put out. It is suggested those models,especially recent ones for continental crustal levels, are nevertheless helpful for us to understand more natures of continentalcrust, the evolution of crust and earth.
