Abstract: Abstract A crustal and uppermost mantle shear-wave velocity model beneath the central and northeastern Tibetan Plateau is obtained from the joint analysis of Rayleigh wave phase dispersions and teleseismic P-wave receiver functions at 188 broadband… read more here.

DOI: 10.1093/gji/ggz345
Abstract: Low-velocity layers within the crust can indicate the presence of melt and lithologic differences with implications for crustal composition and formation. Seismic wave conversions and reverberations across the base of the crust or intracrustal discontinuities,… read more here.
