壳体构造──一种综合大地构造学新概念

壳体是为了把历史大地构造学和动力大地构造学两方面的研究目的、对象及研究方法的优点综合起来，融为一体，以期较全面地研究地球构造问题而建立的一种大地构造单元概念。其特色是同时包含有演化与运动涵义、发展观点与联系观点并重、时空兼顾。它兼具上述两类大地构造单元的性质、特征和功能，是属于历史动力综合大地构造学的构造单元概念。一方面，它虽由历史大地构造单元如地槽区、地台区和地洼区组成，但强调了在空间上迁移的动态而与之有别；另一方面，它与动力大地构造单元的板块概念，虽作为岩石圈块体在形式上近似，但强调了它在时间上演化的动态，以及还有许多其他方面的特点而与之不同。

Crustobody-A New Concept of Integrative Geotectonics

The crustobody is a concept of tectonic element established for integrating the research aims,objects and methods of historic and dynamic geotectonics in order to study the tectonics of the earth in an all-round way.It carries the implications of both evolution and movement,lying equal stress on both development viewpoint and connection viewpoint and giving consideration to both time and space.It has the nature,characteristics and functions of the above-mentioned two tectonic elements.On the one hand,though consisting of historic tectonic elements such as geosynclinal,platform and geodepression(diwa)regions,it puts emphasis on their changing state in spatial migration,thus differing from them.On the other hand,though similar in form to plate,a dynamic tectonic element,it places emphasis on the changing state in its temporal evolution and has other distinguishing characteristics,thus differing from it.
