PRELIMINARY DISCUSSION ON STUDIES OF CONTINETAL LITHOSPHERE

大陆岩石圈和大洋岩石圈有着深刻的差别，运用板块构造理论和模式研究大陆岩石圈会遇到许多特殊的问题。本文从陆缘演化和多个板块构造旋回叠加两方面做了初步探讨，提出岩浆型被动陆缘是独立的一类古陆缘；在辨认后续板块构造旋回叠加中，新构造成分和格局的确定有重要意义。本文还讨论了汲取大陆地质研究经验，在新的学科水平上重新解释传统大地构造学中一些有用概念的意义。

There are sharp contrasts between the continental and oceanic lithosphere,anda lot of problems have arisen when the theory and model of plate tectonics have been ap-plied in the researches into continental lithosphere.This study involves the evolution ofcontinental margins and superimposition of multiple cycles of plate tectonics,proposingmagmatic passive continental margins as an distinguishable type of ancient continentalmargins.The determination of younger structural components and tectonic framework isof very importance in recognizing the superimposition of following cycles of plate tectonicsupon early tectonics.It is significantly important that the experiences from studies of con-tinental geology should be drawn and re-interpretations of some useful conceptions fromtheory of traditional tectonics should be made at an advanced level.
