Enstatite is a mineral; the magnesium endmember of the pyroxene silicate mineral series enstatite (MgSiO 3) – ferrosilite (FeSiO 3). The magnesium rich members of the solid solution series …

Feb 9, 2021 · Here, we report an unprecedently high melting temperature of MgSiO3 at 500 GPa by direct shockwave loading of pre-synthesized dense MgSiO3 (bridgmanite) using the Z …

Post-perovskite (pPv) is a high-pressure phase of magnesium silicate (MgSiO 3). It is composed of the prime oxide constituents of the Earth's rocky mantle (MgO and SiO 2), and its pressure …

Results demonstrate that MgSiO 3 perovskite transforms to a new high-pressure form with stacked SiO 6 -octahedral sheet structure above 125 gigapascals and 2500 kelvin (2700 …

Jan 14, 2009 · We present new equation-of-state (EoS) data acquired by shock loading to pressures up to 245 GPa on both low-density samples (MgSiO3 glass) and high-density, …

Mar 1, 2011 · Liquid MgSiO 3 is a model for the Earth’s magma ocean and of remnant melt present near the core–mantle boundary.

Oct 14, 2005 · Here, we present FPMD simulations of MgSiO 3 liquid over the pressure-temperature range of Earth's mantle, based on density functional theory in the local density …

Mar 7, 2016 · The MgSiO 3 post-perovskite phase is the most abundant silicate phase in a super-Earth’s mantle, although it only exists within the Earth’s lowermost mantle.

We use density functional theory molecular dynamics (DFT-MD) and path integral Monte Carlo (PIMC) simulations to generate a consistent equation of state (EOS) for liquid MgSiO3 that …

Jul 22, 2004 · Here, using ab initio simulations and high-pressure experiments, we show that at pressures and temperatures of the D″ layer, MgSiO 3 transforms from perovskite into a …
