Structural Heterogeneities in Southeast Tibet: Implications for Regional Flow in the Lower Crust and Upper Mantle

(a) 1D velocity models. The solid lines show the optimal and velocity models used in this study. The short dashed lines indicate the initial velocity model inferred from the previous tomographic and receiver function studies [5, 16] and the IASP91 model [17]. (b) The grid model adopted for the final tomographic inversion. The grid spacing is 50–100 km in N-S and E-W directions and 10–200 km in depth. Gray crosses denote the seismic stations. In areas with more seismic stations, a smaller grid spacing is adopted.
