Fig 16. Regional setting of GSN station ARU (open triangle) and the geometry of inferred anisotropy in the lithosphere. Grey lines - topography contours at 330 and 560 m. Wide grey line: the main Uralian Fault Zone. Open lines: locations of active-source seismic studies in the region. Open arrow: the symmetry axis of lower-crustal anisotropy. Grey bars: inferred fast axes of anisotropy for the two layers in the mantle. (Postscript version)
