摘要:
本文通过综述近年西特提斯带主要缝合带的研究进展及所代表洋盆的发育特征,提出了古特提斯缝合带可能的位置和俯冲消亡方式。结合区域资料探讨了西特提斯带古生代末—中生代洋陆构造格局,认为东、西古特提斯洋完全可以类比,自晚古生代末西特提斯带主要受古特提斯大洋双向俯冲制约,在俯冲带后缘以二叠纪裂谷带为基础逐渐发展成中生代多岛弧盆系的新特提斯构造格局,西特提斯造山系主要表现为弧后洋盆消减造山作用。

Abstract:
The research progress of the main suture zones in the west Tethysides and the development characteristics of the oceanic basin represented by them are reviewed. We propose the potential location of the Paleo-Tethys suture and summarize a brief evolution of the Paleo-Tethyan Ocean. Combining with regional geological data, this paper discusses the tectonic framework of the west Tethysides during the latest Paleozoic to the Mesozoic. The similar tectonic evolution is also found within the Paleo-Tethys which can be compared between the east and west parts. From the latest Paleozoic onward, the west Tethysides realm was mainly affected by double-sided subduction of the Paleo-Tethys.The Neo-Tethys was characterised by archipelagic arc-basin system during the Mesozoic, which succeed the Permian rifts in the aftermath of the Paleo-Tethys subduction. The west Tethysides was mainly manifested by the orogenesis of collaped back-arc basin.
Key words:  composite arc-basin system  Tethysides  suture zone  oceanic plate geology
