Fig. 3: Vertical crustal seismic compressional velocity sections.

Velocity sections for different parts of the study area shown together with vertical models from other regions with thick crust (Moho depth >45 km) and the Dharwar Craton in India7, as well as the global average crustal structure8 of orogens and cratons. LT Lhasa Terrane, NW Northern-western. Only the velocity sections for the Lhasa Terrane lack a high-velocity lower crust corresponding to a mafic composition, which makes its structure unique.
