摘要:
以青藏高原为主体的东特提斯构造演化一直是国内外地学研究中关注的重大科学问题。为了更全面、更深入地认识青藏高原及东特提斯构造域的形成演化历史,本文在综述前人有关特提斯构造域时空演变和演化阶段研究的基础上,重点总结了近年来1∶5万区域地质调查中取得的最新研究进展,提出昌宁-澜沧构造带原-古特提斯连续演化、南冈底斯构造带古-新特提斯连续演化新认识,构建了青藏高原及东特提斯构造域大陆边缘多岛弧盆系时空格局和原、古、新三阶段构造演化模式。
关键词:  蛇绿岩  增生杂岩  高压变质岩  多岛弧盆系构造  特提斯构造演化

Abstract:
The tectonic evolution of East Tethys, especially the tectonic evolution of Qinghai-Tibet Plaeau, has been one of the most important scientific issues in the world. In order to understand the tectonic evolution history of Eastern Tethys and Qinghai-Tibet Plateau more comprehensively and deeply, this article focuses on summarizing the current progresses of regional geological survey (1∶50 000) in recent years and giving an overview on previous achievements about Tethyan spatio-temporal evolution and evolutionary stages. A new point of view that the evolutionary processes were probably continuous from Proto-Tethys to Paleo-Tethys in the Changning-Lancang tectonic zone and from Paleo-Tethys to Neo-Tethys in the southern Gagdise tectonic zone has been put forword in the article. Furthermore, the spatio-temporal framework of archipelagic arc-basin system in continental margins and tectonic models have been constructed for the evolwtionary processes of the Proto-Tethys, Paleo-Tethys and Neo-Tethys of Qinghai-Tibet Plateau and East Tethys tectonic domain have been established reasonably.
Key words:  ophiolite  accretionary complex  high-pressure metamorphic rock  archipelagic arc-basin structure  tectonic evolution of Tethys
