The composition of inner core
WebIn 1929 a large earthquake occurred near New Zealand. Danish seismologist Inge Lehmann “the only Danish seismologist,” as she once referred to herself—studied the shock waves and was puzzled by what she saw. A few P-waves, which should have been deflected by the core, were in fact recorded at seismic stations. Lehmann theorized that these ... WebApr 14, 2024 · Hexagonal close-packed (hcp) structured Fe-Ni alloy is believed to be the dominant phase in the Earth's inner core. This phase is expected to contain 4–5% light elements, such as Si and H. While the effects of individual light element candidates on the equation of state of the hcp Fe metal have been studied, their combined effects remain ...
