Heterogeneity and anisotropy of Earth's inner core
A Deuss - Annual Review of Earth and Planetary Sciences, 2014 - annualreviews.org
Seismic observations provide strong evidence that Earth's inner core is anisotropic, with
larger velocity in the polar than in the equatorial direction. The top 60–80 km of the inner …

Anisotropy in the deep Earth
B Romanowicz, HR Wenk - Physics of the Earth and Planetary Interiors, 2017 - Elsevier
Seismic anisotropy has been found in many regions of the Earth's interior. Its presence in the
Earth's crust has been known since the 19th century, and is due in part to the alignment of …
