摘要
板块构造学说是高度成功的地球科学理论。大洋岩石圈与大陆岩石圈之间的多岛弧盆系构造域是板块构造登陆的入门向导。青藏高原大地构造研究实践表明,青藏高原是板块构造登陆的研究基地。众多蛇绿岩带、混杂岩带和火山岩浆弧带等的识别,支持洋陆转换多岛弧盆系构造模式,可用来解释特提斯和亚洲大陆的形成和演化。
The theory of plate tectonics is one of the highly successful theories in the geosciences. The rudimental guide of the plate-tectonic theory landing on continent is the archipelagic arc-basin system between the oceanic lithosphere and continental lithosphere. The study of tectonics on the Qinghai-Tibetan Plateau indicates that the Qinghai-Tibetan Plateau is the ideal research base of the plate-tectonic theory landing on the continent. The evolution of the Tethys and formation and evolution of the Asian continent can be interpreted by the tectonic model of the archipelagic arc-basin system in the process of transition between oceanic crust and continental crust, which is supported by the recognition of numerous ophiolitic belts, mélange zones and volcanic-magmatic arcs on the Qinghai-Tibetan Plateau and adjacent regions.
