基于青藏高原巨厚的地壳结构和复杂的地球物理场特征,提出依据地震活动与波场标志、岩石层结构与速度场标志、古地磁标志、位场标志、温度场标志、地质与构造标志作为进行青藏高原地体划分的原则.据此,由北向南将青藏高原及其相邻地带划分为7个地体,即柴达木地体、昆仑地体、可可西里-巴颜喀拉地体、羌塘地体、拉萨-冈底斯地体、喜马拉雅地体和恒河平原地体,它们的分布格局与特征对青藏高原的形成、演化和板块运动及动力机制的研究起着重要的作用.
Based on the crustal structure and complicated geophysical field characteristics of the huge thickness of the Qinghai-Tibet Plateau, this paper puts forward a method based on the seismic activity and wave field markers, lithosphere structure and velocity field markers, paleomagnetic markers, field markers, temperature field markers, geology and tectonic markers To carry out the principle of dividing the Qinghai-Tibet Plateau. Accordingly, from north to south, the Qinghai-Tibet Plateau and its adjacent areas are divided into seven terraces, that is, the Qaidam terrane, the Kunlun terrane, the Hoh Xil-Bayan Harrat terrane, the Qiangtang terrane, the Lhasa-Gangdise Sri Lanka, the Tula body, the Himalayan terrain and the Ganges plains. Their distribution patterns and characteristics play an important role in the study of the formation and evolution of the Tibetan Plateau and the plate motions and dynamics.
