Depth-dependent anisotropy in the Earth’s inner core linked to chemical stratification [PDF]
Nature CommunicationsSeismic anisotropy in the Earth’s inner core (IC), including the heterogeneous, depth-dependent anisotropy structure, is a well-documented yet poorly understood feature plausibly related to the alignment of iron alloy crystals. Here, we report the effect
