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 …

Melting curves of Ca‐perovskite (pure CaSiO3) were determined by ab initio density
functional theory, using two solid‐liquid coexistence methods and two free energy …

Classic lamellar clinopyroxene-ilmenite intergrowths (type 1) are extended to include
discovery of olivine-ilmenite-perovskite-wüstite (type 2) and olivine-spinel-perovskite (type …

摘要布里奇曼石(bridgmanite) 和毛钙硅石(davemaoite) 是下地幔主要的端元矿物,
是构成下地幔的重要基石. 矿物物理学新的研究发现, 在高温高压条件下这两种矿物可以发生混 …

Iron partitioning among the main lower mantle phases, bridgmanite (Bm) and ferropericlase
(Fp), has non-monotonic behavior owing to the high-spin to low-spin crossover in ferrous …

Bridgmanite and davemaoite are the primary minerals in the deep mantle and are important
building blocks of the lower mantle. Recent studies in mineral physics have found that the …

The solid solution between CaSiO3 and MgSiO3 perovskites is an important control on the
properties of the lower mantle but the effect of one of the most important impurity elements …

Magnesium silicate perovskite in the form of bridgmanite (bdg) and Calcium silicate
perovskite (Ca-pv) have similar chemical structures and may mix into a single perovskite …

Recreating the extreme conditions of the deep Earth and other planetary interiors poses
significant experimental difficulty. The primary tool for investigations of material properties at …

The chemical composition of mid-ocean ridge basalt (MORB) differs from the pyrolite
composition of Earth's mantle, such as containing more Si and Ca, and less Mg. When …
