1:250000 geological mapping has further revealed the mysteries of the tectonics of the Qinghai-Tibet Plateau. The Altun Mountains are not of the Tarim massif, but a part of the Kunlun-Qilian-Qinling orogenic system; the Altun fault is a large transform fault; the Muztag-Maqên suture zone and Jinshajiang suture zone are both Variscan ones; the Songpan-Garzê area in the Triassic was a huge turbidite basin on the southern margin of Laurasia; the Gangdise belt underwent the important Indosinian orogenic movement; an ocean basin that persisted from the Paleozoic to Triassic did not exist, i.e. the so-called Paleo-Tethys or permanent Tethys was not in existence in the Qinghai-Tibet Plateau. In the Paleozoic, most parts of China, including the Sino-Korean, Yangtze and Tarim massifs and the Qinghai-Tibet Plateau, were located in south of the main ocean basin—the Central Asian-Mongolian sea way—of the Paleo-Asia ocean, belonging to the northern margin of Gondwana. The Yarlung Zangbo and Bangong -Nujiang belts were twins in the Tethyan Ocean, which began to develop into two ocean rift belts in the Triassic. The Tethyan Ocean with the Yarlung Zangbo belt as the main ocean basin belt began to be subducted in the Late Triassic and experienced a process of pulsatory plate convergence orogeny including the Indosinian, Yanshanian and Himalayan stages.
