Abstract

Packing the Core The packing and arrangement of atoms in Earth's solid inner core can dictate processes such as core growth and rotation. Seismology and modeling suggest the inner core is composed primarily of iron, but the structure is less clear due to anisotropic splitting of seismic waves. Tateno et al. (p. 359 ) performed static compression experiments on pure iron at the extremely high pressures and temperatures found in the inner core and saw that iron prefers a hexagonal close-packed structure, as opposed to cubic structures. The results help to explain the observed seismic anisotropy, and also suggest that individual iron crystals in the core may prefer orienting themselves with their long crystallographic axes parallel to Earth's rotation axis.
