    摘要:

    大地构造学是地球科学最具前沿性和纲领性的学科领域。国际大地构造学假说和理论的出现,经历了20世纪初的槽台学说,到大陆漂移- 海底扩张发展再到20世纪60年代的板块构造学说。20世纪,在槽台学说的基础上,中国大地构造研究提出了地质力学、地洼、波浪- 镶嵌、多旋回、断块等学说思想。在板块构造学说引入中国后,中国学者全盘接受了板块构造理论。从此开始,以板块构造为基础的学说思想,研究和探讨中国大地构造及演化。在此基础上取得了中国构造演化系统性的认识。然而这些研究成果是否具有普适性,是否具有全球格局的普遍性以及对于全球构造理论的提升是否具有足够的贡献,需要进行深入地思考。特别是全球大地构造格局形成的核心问题如超大陆的形成、板块构造的起源、大陆的稳定性等依然处于探索中。正因如此,在几十年来的研究和发展中,仍有一些关键问题存争议,如板块构造与大陆构造的关系和内在联系,大陆是如何演化的,以及超大陆的形成与裂解,板块构造最早出现的时间及特征等全球关注的科学问题,以及中国大陆构造及演化的独特性是否具有全球普遍性,依然是未来研究的方向。针对此,本研究在全球大地构造及中国大地构造研究的基础上,分析了中国大地构造研究的核心问题。以全球格局为视角,分析和提出了解决关键问题的可行性,强调指出全球构造包括了板块构造(plate tectonics)和陆内构造(intracontinental tectonics),即跨大陆(贯穿大陆)构造(transcontinental tectonics)的思想。

    Abstract:

    Research and development in tectonics stand at the forefront of geosciences, establishing critical frameworks for understanding Earth' s dynamic processes. The evolution of international tectonic concepts progressed from the geosyncline- platform theory in the early 20th century, through models of continental drift and oceanic floor spreading, culminating in the establishment of the plate tectonics theory in the 1960s. Chinese tectonic studies followed a similar trajectory, initially rooted in the Geosyncline- Platform hypothesis. Subsequently, various additional theories emerged, such as geomechanics, Diwa, Bolang- Xiangqian, multiple- cycle, and fault block hypotheses. With the introduction of plate tectonics, Chinese geologists largely adopted it as the primary model, leading to significant advancements in understanding the tectonic framework and evolution of the Chinese continent. Although the accuracy of specific models may vary, Chinese tectonic studies have made substantial progress, contributing systematic insights within the plate tectonics paradigm. However, these advancements, while aligned with general or specific global tectonic trends, have yet to provide definitive or distinct contributions to broader global tectonic theory, particularly in resolving key issues regarding the formation and evolution of global tectonics. These challenges include fundamental questions about the relationship between plate tectonics and continental tectonics, the processes driving continental evolution, and the mechanisms behind supercontinental formation and breakup- issues of ongoing concern to geologists worldwide. Even within the context of Chinese continental tectonics, debates persist regarding its unique versus universal characteristics within the global tectonic framework. These unresolved issues are pivotal for future research. In this paper, we argue that the development of Chinese tectonics cannot be fully resolved through plate tectonics alone. Future studies should integrate global tectonic principles, considering the fundamental and natural features of Earth' s structure. Moreover, it is essential to consider the role of both plate tectonics and intracontinental tectonics, asserting that global tectonics encompasses more than just plate boundaries; it must also include intracontinental and transcontinental dynamics.
