对青藏高原北部NNW向构造的地质地貌组合特征、活动方式及形成年代等问题进行的研究表明,NNW向构造在地貌上由西向东表现为隆、拗相间排列的构造格局。其中NNW向活动断裂依次发育在隆起带的东缘,形成伴有褶皱构造的逆冲-挤压构造带。拗陷带则由一系列位于隆起带之间的压陷性盆地带组成。NNW向构造活动强烈,特别是在第四纪中、晚期以来,它们不仅制约着青藏高原北部区地质地貌的发生和发展,而且还在地震活动及强震孕育和发生过程中扮演着重要的角色,NNW向隆起从第三纪末期至第四纪初期开始发育,但大规模隆起发生在第四纪中更新世以来。
The study on the geomorphologic assemblage characteristics, activity patterns and age of NNW tectonics in the northern part of the Qinghai-Tibet Plateau shows that the NNW tectonics behave as a structural pattern of uplift and reclamation in west-east direction from west to east. Among them, the NNW developed active faults in turn on the eastern margin of the uplift belt, forming a thrust-compression belt with fold structure. The depression zone consists of a series of collapsed basin zones between the uplifts. NNW has a strong tectonic activity, especially since the late Quaternary, which not only restricted the occurrence and development of the geology and geomorphology in the northern part of the Qinghai-Tibet Plateau, but also played an important role in the occurrence and occurrence of earthquakes and strong earthquakes NNW uplifts began to develop from the end of Tertiary to the beginning of Quaternary, but large-scale uplift occurred in the mid-Pleistocene.
