| 英文摘要 | In the Proto-Tethys Ocean there are many microcontinents/continents such as the Tarim, Qilian, Qaidam, Yangtze and Cathaysia, Indochina, Lanping-Simao (Sibumasu) blocks/micro-continental blocks, between most of these blocks developed a series of ophiolite belts or high-pressure and ultrahigh-pressure metamorphic belts at the end of the Early Paleozoic. Obviously, the Proto-Tethyan tectonic domain underwent the complex ocean-continent configuration, break-up and assembly processes from Supercontinent Rodinia's breakup to Supercontinent Pangea's assembly. However, so far their attribute, affinity and collision process among different continents/microcontinents in the Proto-Tethys Ocean remain much controversy. This is critical for restoration and reconstruction of tectonic background of Supercontinent Pangea assembly. Therefore, this paper adopts the comprehensive tectonic comparison method in order to establish affinities and ocean-continent configuration of the Proto-Tethys Ocean and the related continental block/micro-continental blocks, and determine the timing and sequences of assembly among these Proto-Tethyan micro-continental blocks. The results show that, the North China Block had not affinitive relation to the Gondwana, the other continents/micro-continental blocks such as the Yangtze, Cathaysia, Tarim, Qaidam, Alax, North Qinling-Central Qilian-Central Altyn, Oulongbuluke, North Qiangtang, South Qiangtang, Lhasa, Lanping-Simao and Indochina have an affinity to Gondwana in the earlier of Early Paleozoic. During about 450 similar to 400Ma these series of continental blocks/micro-continental blocks experienced gradually southward subduction and accretion to the eastern segment of the northern margin of the Gondwana, resulting in the Proto-Tethys Ocean closure and one supercontinent called Proto-Pangea. The Tarim-North China Block and the Greater-South China Block separated from the Proto-Pangea since 380Ma to result in formation of the Mianlue and the Paleo-Tethys oceanic crusts. Until 240 similar to 220Ma they assembled northward gradually to develop eventually the Laurasia. At this time, it resulted in the formation of the Supercontinent Pangea. |
