| 笔者在长期从事青藏高原地质工作和综合大量实际资料的基础上,提出了特提斯的演化与三大陆块群相互裂变-聚变作用过程密切相关,特提斯洋从萌生、扩展、萎缩、消亡到汇聚造山的整个演化过程,受控于全球洋-陆时空结构的转换;阐述了全球洋-陆构造体制的转换论、多岛弧盆系统论、造山作用过程论,并依此“三论”对青藏高原及周边地区的大地构造单元进行了划分,概要阐述了各个构造单元的基本特征。 |

| Abstract: |
| The geology of the Qinghai-Xizang Plateau as the bulk of the eastern Tethyan tectonic domain is interpreted within the framework of archipelago orogenesis. On the basis of the long-term field investigation and plentiful data available, the Tethyan evolution is considered to be closely bound up with the breakup and assembly of the three (Laurasia, Gondwana and Pan-Cathaysian) continental strips on the globe. The Tethys Ocean went through a variety of evolutionary processes from initiation and development,through collapse and consumption, to closure and orogenesis, and was always controlled by the evolution of the global oceanic-continental spatio-temporal patterns. The tectonic units are divided for the Qinghai-Xizang Plateau and its adjacent areas according to the ideas about the transition of the global oceanic-continental tectonic regimes, archipelagic arc-basin systems and orogenic processes, and the fundamental features of varying tectonic units are described in detailed. |
