沿亚洲大陆东缘,包括海陆过渡带,已经证明有一个构造体系,它由一些直径为2000—4000km的中心型巨型地貌构造(mega—MCT)和一些绵延数百或数千公里的区域性断裂带(trans-regional faults)组成。这些地貌构造确定了本地区的地质、地貌基本特征。巨型的MCT是一些内生构造,它形成于前寒武纪、并在其漫长的历史过程中经历了反复的构造岩浆活动,同时,也引起地质和构造结构以及地形的重要重建。最后一幕的重新活动发生在晚中生代,这时一个巨型MCT链的构造沉降产生了一些东亚边缘海盆。与此同时,大陆型的巨型MCT经历了一次整体的隆升。作者提出,有一个从前寒武纪一直持续至今的大陆边缘拉张过程在地貌构造的区域演化中起着主要的作用。世界上许多其它的大陆边缘在显生宙时期都经历了拉张和构造沉降。这种现象可以用地球的持续膨胀过程予以很好的解释。
Along the eastern margin of the Asian continent, including the transition zone between land and sea, a tectonic system has been established that consists of mega-MCTs with a diameter of 2000-4000 km and regional faults stretching hundreds or thousands of kilometers With trans-regional faults. These topographies confirm the basic features of geology and landform in this area. The massive MCTs are endogenous structures that formed in the Precambrian and underwent repeated tectono-magmatic events during their long history, while also causing important reconstruction of geology and tectonic structures and topography. The last scene of reactivation occurred in the late Mesozoic, when the tectonic subsidence of a giant MCT chain produced some East Asian marginal seas. At the same time, the continental giant MCT experienced an overall upturn. The authors suggest that there is a major role played by the continent’s stretching process from the Precambrian to the present in the evolution of the geomorphic regions. Many other continental margins in the world underwent extensive and tectonic subsidence during the Phanerozoic. This phenomenon can be well explained by the sustained expansion of the earth.
