台湾岛-大陆碰撞涉及四个地球动力学过程：洋内俯冲；初始弧大陆碰撞；先进的大陆碰撞；以及塌陷/俯冲。这些过程现在同时发生在北纬 19-24 度 30'，但自晚中新世以来依次向南进行。尽管全岛的地质和地球物理特征似乎从北到南逐渐变化，但它们在各个构造体系中是截然不同的。以目前情景为基础进行比较，认为Timer处于初始陆陆碰撞阶段，而巴布亚新几内亚和乌拉尔则进入了陆陆碰撞高级阶段。然而，科西嘉岛代表着比台湾更先进的阶段，台湾先前堆积的区域已经倒塌并被完全移除。 (C) 2000 Elsevier Science B.V. 保留所有权利。
The Taiwan are-continent collision involves four geodynamic processes: intra-oceanic subduction; initial arc-continent collision; advanced are-continent collision; and are collapse/subduction. These processes now occur simultaneously in 19-24 degrees 30'N but have operated sequentially southward since the Late Miocene. Although the geological and geophysical features appear to change progressively from north to south across the island, they are distinct within individual tectonic regimes. Using the present scenario as a basis for comparison, it is suggested that Timer is at the initial are-continent collision stage, while Papua New Guinea and Urals proceeded to the advanced are-continent collision stage. However, Corsica represents an even more advanced stage than in Taiwan, where a previously accreted are has collapsed and been totally removed. (C) 2000 Elsevier Science B.V. All rights reserved.
