Recent studies have shown that the eastern NCC (ENCC) has undergone significant lithospheric thinning and destruction since the late Mesozoic. Destruction of the cratonic lithosphere is necessarily accompanied by crustal deformation. Therefore, a detailed crustal …

WebNov 23, 2024 · We obtain a 3-D crustal radial anisotropy model of NE Tibet using the ChinArray-Himalaya II seismic array. We observe an LVZ and strong positive radial anisotropy (∼4%) beneath the SGT, indicating the presence of middle-to-lower crustal channel flow. Zero or slightly negative radial anisotropy is observed beneath the Qilian … WebJun 1, 2024 · Using data from 675 stations deployed by the ChinArray project, ...
