.We investigate seismic layering i.e., discontinuities, regions of anomalous velocity gradients, and anisotropy and its .lateral variability in the upper mantle by comparing seismic models from three tectonic regions: old;100 Ma Pacific .plate, younger;40 Ma Philippine Sea plate, and Precambrian western Australia. These models were constructed by combining two data sets: ScS-reflectivity profiles, which provide travel times and impedance contrasts across mantle .discontinuities, and observations of frequency-dependent travel times of three-component turning S, sS, SS, sSS, SSS, Sa .and surface R, G waves, which constrain the anisotropic velocity structure between discontinuities. The models provide a1 1 better fit to observed seismograms fr...
