| 英文摘要 | The Proto-Tethys Ocean is a complicately-originated oceanic basin originated from Supercontinent Rodinia breakup and existed from Neoproterozoic to the end of the Early Paleozoic. It was located in the range of north of the Yunnan-Burma-Thailand/Baoshan (Sibumasu) micro-continental blocks and south of the Tarim-North China Block. There is still controversy for a long time on the southern and northern border faults and the late Early Paleozoic subduction polarity of the Proto-Tethys Ocean. It is important for understanding tectonic background, restoration and reconstruction of Supercontinent Pangea assembly. Therefore, this paper used the integrated methods for the latest results of field geology, tectonics, magmatism, sedimentology, geochemistry and tectonic chronology and tomographic imaging, to identify the positions of the southern and northern border faults of the Proto-Tethyan Tectonic Domain, and determine the subduction polarity of the Proto-Tethys Ocean. Integrated analysis results show that to the north is bounded by the paleoLuonan-Luanchuan Suture (or Kuanping Suture) and its extension to West Kunlun; the southern boundary is the Longmu CoShuanghu-Changning-Menglian Suture. The Tarim-Alax-North China Block in the north of the Proto-Tethys Ocean had a southward subduction polarity and collided with the Gondwana along the northern margin of the Gondwana in the Early Devonian, forming a giant orocline now preserved in the Qilian-Altyn Tagh-Qaidam segment of the Central China Orogen. The south branch of the Proto-Tethys Ocean may be closed, making the Greater South China Block including the North Qiangtang, Ruoergai, Yangtze and Cathaysia, Bureya-Jiamusi and Indochina blocks a southward subduction and accretion to the northern margin of the Gondwana in Devonian. |
