青藏高原于新生代初全面完成了特提斯洋陆转换,成为统一的陆块,步入陆内演化阶段。青藏高原新生代演化的最重大事件是陆内强烈造山作用与高原强烈地隆升作用。新生代高原大规模陆内造山和隆升驱动的沉积建造,与前新生代的特提斯多岛弧盆演化体系的地层建造格架大不相同.因此,在盆山耦合与高原隆升—沉积响应的思想指导下,识别出青藏高原新生代地层发育的盆地共98个。据98个盆地的地层发育特点,划分为南疆—西昆仑(I)、柴达木—祁连—西秦岭(II)、羌塘—川西(III)、扬子西缘(IV)和冈底斯—喜马拉雅—恒河(V)共5个地层区,进一步又细分为13个构造—地层分区。
The Qinghai-Tibet Plateau completed the complete Tethys ocean-land conversion in the early Cenozoic and became a unified land mass and entered the stage of intra-continental evolution. The most significant event of the Cenozoic evolution of the Qinghai-Tibet Plateau is the intense intra-continental orogenic uplift and intense uplift of the plateau. The large-scale intracontinental orogeny-driven depositional deposition in the Cenozoic plateau is quite different from the stratigraphic framework of the pre-Cenozoic Tethuodor arc basin evolution system. Therefore, in the basin-mountain coupling and plateau uplift-sedimentation Under the guidance of response, a total of 98 basins of Cenozoic stratigraphic development in the Qinghai-Tibet Plateau have been identified. According to the characteristics of stratigraphic development of 98 basins, they are divided into four types: the southern Kunlun (I), Qaidam-Qilian-West Qinling (II), Qiangtang-Western Sichuan (III) Sri Lanka - the Himalayas - Ganges (V) a total of five stratum, further subdivided into 13 tectonic - stratigraphic division.
