Short summary

New splitting measurements are obtained using direct-S waves by correcting source-side contamination using data from southeastern Tibet, near Namcha Barwa. A highly deformed lithospheric and sub-lithospheric mantle reveals fast-axis patterns close to the surficial expressions of the local geology. Significant anisotropy observed at stations where null or no measurements were obtained in earlier studies indicates the importance of using direct-S waves for anisotropic measurements.
