Broadband Seismic Deployments for Imaging the Upper Mantle Structure in the Lützow-Holm Bay Region, East Antarctica
Figure 10
(a) Schematic illustration of the two-layered model for obtaining anisotropy. (b) Upper mantle anisotropy in LHB derived from SKS splitting (after Usui et al. 2007 [16]). At stations AKR, LNG, SKL, SYO, and TOT, the lower layer anisotropy was suspected to be caused by recent asthenospheric flow. For almost all other stations, the direction of the upper layer anisotropy (corresponds to the “lithosphere”) was parallel to NE-SW convergence during the Pan-African age.
