【摘要】 指出板块构造理论在解释大陆构造中的不足之处,从而在进一步深化板块构造理论发展的同时,构建大陆构造理论体系;通过长期大陆构造研究实践并利用国内外大陆造山带的6个例子提出有关大陆的基本问题,诸如早期大陆起源、超大陆方式演化的大陆演化机制以及大洋和大陆岩石圈的本质不同和构造旋回;说明大陆是由板块构造(包括可能的板块构造远程效应)和大陆自身机制分别形成的组分的拼合体.主张大陆有自身的机制操控它的起源、保存和演化.在排除了来自板块边缘以及板块远程效应的作用力的前提下,出现在陆内环境的造山作用可由大陆本身尤其可能由陆内中小块体之间的相互作用引发.需要强化大陆构造研究,在深化板块构造理论的同时,探索和创建大陆构造理论体系.更多还原

【Abstract】 From our long-term study on continental geology,it has been realized that the theory of plate tectonics is the main guiding principle,but it has limitations in the recognition and interpretation of continental geology.This paper presents firstly six specific examples of continental tectonics typified by orogens,by which it attempts to demonstrate that a continent is the tectonic collage comprising the components formed by plate tectonics(including the far field effect from plate active boundaries) and intracontinental mechanisms,respectively.It is proposed that the orogeny occurring in the intracontinental setting can be initiated by continent itself and more likely by the interaction of different blocks within a continent when there was no involvement of plate tectonics and the distant effect derived from plate tectonics.Furthermore,the authors raise a number of questions concerning the fundamental continental issues such as the origin of early continents,the mechanism of continental evolution in the form of supercontinent and the essential differences of oceanic and continental lithospheres and their tectonic cycles.These issues are not related to plate tectonics or cannot be solved by the theory of plate tectonics.In summary,besides plate tectonics works on continents,continents have their own law governing the origin,preservation and evolution of continents.Therefore,it is suggested to further develop the continental study while deepening the theory of plate tectonics.更多还原
