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

Figure 4

Plan views of the checkerboard resolution tests (CRTs) for the P- and S-wave tomography. The input amplitudes of the velocity perturbations are ±2% at every grid nodes. The layer depth is shown at the lower-left corner of each map. The scale for the velocity perturbations (in %) relative to the 1D initial velocity model is shown at the bottom.
