摘要:
提要:大陆动力学的理论与研究开启了人们一个新的思路:在确认中国大陆构造格架、划分构造单元时,除了前寒武纪基底、南华—印支期生物地层格架以外,不能不考虑中-新生代以来重大的陆内变形事件所产生的陆内变形(大型走滑断裂、推覆构造、挤出构造)对印支与前印支期所形成大陆构造格架大幅度的改造,因此对前印支期构造单元的性质需要通过构造复位来重新认识。通过构造复位认为:阿拉善、中祁连—柴达木、北羌塘等微陆块和塔里木板块是一个整体的克拉通——西域板块,不存在整体的昆(仑)—祁(连)—秦(岭)海洋板块,早古生代满加尔—北祁连坳拉槽-小洋盆和晚古生代东昆仑—阿尼玛卿—金沙江裂陷洋盆可能是由古特提斯洋脊楔入所引起的,类似于现今的红海—亚丁湾。本文拟从阿拉善、北羌塘地块的构造归属、西域板块的确认;中国境内北亚构造域的构造划分和晚侏罗—早白垩世陆内变形、中亚挤出构造;中朝与扬子—华南板块划分和南北黄海、朝鲜半岛的构造归属等方面,来讨论有关中国及邻区大陆构造格架的一些争议问题。

Abstract:
Abstract:A new way of thinking is opened up by the generation of the continental dynamic theory and its application to the study of tectonics of Chinese mainland. The Precambrian basement and the South China-Indo-China stratigraphic framework are regarded as the essential factors in the outlining and subdivision of the tectonic framework of Chinese mainland. Nevertheless, it is also necessary to carry out studies of important intracontinental deformation structures such as large scale strike-slip faulting, nappe structures and extrusion tectonics as well as their influence on the tectonic framework formed during and before the Indo-China stage. The properties of the pre-Indo-China tectonic units should therefore be reevaluated through tectonic reconstruction. A study of the tectonic reconstruction of Western China has led the authors to believe that Alxa, Mid-Qilian, Qaidam and northern Qiangtang blocks as well as Tarim plate belong to a unified craton of Xiyu Plate, while Kunlun-Qilian-Qinling ocean plate is not existent. The Early Paleozoic Maijia'er-North Qilian small ocean basin and Late Paleozoic East Kunlun-Animaqing-Jinshajiang faulted depression ocean basin might have resulted from the wedging action of the ridge of Paleo-Tethys ocean, and the environment must have been quite similar to that of the present Red Sea-Aden gulf. This paper deals with some of the basic controversies concerning the tectonic framework of China and its adjacent areas, with an investigation of the tectonic evolution of Chinese mainland in such aspects as the properties and ascription of Alxa and northern Qiangtang blocks, the confirmation of the existence of Western China plate, the tectonic subdivision of the North Asian tectonic domain in China, the Late Jurassic and Early Cretaceous intracontinental deformation and Central Asia extrusion tectonics, the subdivision of Sino-Korean plate and Yangtze-South China plate and the ascription of the southern North Yellow sea and Korean peninsula.
Key words:  tectonic framework of Chinese mainland  tectonic reconstruction of intracontinental deformation  tectonic reconstruction  Western China plate  Central Asia extrusion tectonics
