Cross-section showing lithospheric structures of the Tibetan plateau. a The integrated schematic cross-section in western Tibet. The lithospheric structure is derived from the seismic data5,6; the crustal tectonic structure is from Searle et al.67 and Yin and Harrison3. b The integrated schematic cross-section in central–eastern Tibet, which is modified after Owens and Zandt13 and Ye et al.40. The weak layer in the middle crust is after Wang et al.68. The mantle flow underneath central and northern Tibet is supposed to be eastward69. The locations of both profiles are marked in Fig. 1
