  • 1-4 suggest that the Earth's solid inner core is elastically anisotropic, with the fast direction nearly parallel to the rotation axis. Compressional body- wave data also suggest that the anisotropy increases with turning depth, with a maximum anisotropy of 3-4% (refs 5-7). Here I propose that the inner core's elastic anisotropy and the depth dependence of the anisotropy may be due to solidification textur- ing that results from the dendritic growth of iron crystals. I demonstrate through… CONTINUE READING
