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.

1：25万地质填图进一步揭开了青藏高原地区大地构造的奥秘：阿尔金山是昆仑，祁连-秦岭造山系的一部分；阿尔金断裂确是一条大型转换断层；木孜塔格-玛沁缝合带和金沙江缝合带均是华力西缝合带；松潘甘孜三叠系沉积盆地是劳亚大陆南部边缘的浊积岩盆地；冈底斯带曾经历了重要的印支造山运动；不存在从古生代延续到三叠纪的大洋盆地，即不存在所谓古特提斯或永久特提斯；古生代时期，在青藏高原地区亦不存在具古生物，古地理分隔意义的大洋盆地，当时，包括中朝，扬子，塔里木以及青藏高原地区在内的中国大部分均位于古亚洲洋主洋盆——中亚-蒙古带之南，属冈瓦纳大陆结构复杂的北部边缘；雅鲁藏布江和班公湖-怒江带是特提斯洋中的孪生姊妹，它们均是从三叠纪起就发展成大洋裂谷带的；以雅鲁藏布江带为主洋盆带的特提斯洋，从三叠纪晚期开始消减，经历了印支，燕山，喜马拉雅3个阶段脉动式板块汇聚造山过程。
