Starting from the late 1980s, several groups of lower-mantle mineral inclusions in diamond
have been found. Three associations were established among them: juvenile ultramafic …

The Urey ratio describes the contribution of internal heat production to planetary‐scale
energy balance, and knowing this thermal budget for Earth is essential to understand its …

Accurate knowledge of the mineralogy is essential for understanding the lower mantle,
which represents more than half of Earth's volume. CaSiO3 perovskite is believed to be the …

Mantle plumes originate at depths near the core− mantle boundary (~ 2,800 km). As such,
they provide invaluable information about the composition of the deep mantle and insight …

High-pressure Mössbauer spectroscopy on several compositions across the (Mg, Fe) O
magnesiowüstite solid solution confirms that ferrous iron (Fe2+) undergoes a high-spin to …

It is known that GPS time series contain a seasonal variation that is not due to tectonic
motions, and it has recently been shown that crustal seismic velocities may also vary …

Recent studies have indicated that a significant amount of iron in MgSiO3 perovskite (Pv) is
Fe3+ (Fe3+/ΣFe= 10–60%) due to crystal chemistry effects at high pressure (P) and that …

Ferropericlase is the second most abundant mineral in Earth's lower mantle and knowledge
of its elastic properties at relevant conditions is needed to adequately interpret seismic …

The thermal conductivity of the lower mantle plays a major role in shaping the structure and
dynamics of the region. However, the thermal conductivity of lower mantle minerals are, at …

We examine the problem of obtaining the thermal structure and bulk chemical composition
of the lower mantle from its seismologically determined velocity and density profiles, and the …
