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 are common rock-forming minerals found in igneous and metamorphic rocks. The intermediate composition, (Mg,Fe)SiO.

2004年5月7日 · 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-kilometer depth near the base of the mantle) with an increase in density of 1.0 to 1.2%.

2021年2月9日 · Here, we report an unprecedently high melting temperature of MgSiO 3 at 500 GPa by direct shockwave loading of pre-synthesized dense MgSiO 3 (bridgmanite) using the Z Pulsed Power Facility. We...

MgSiO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Mg2+ is bonded in a 4-coordinate geometry to eight O2- atoms. There are a spread of Mg–O bond distances ranging from 2.04–2.46 Å. Si4+ is bonded to six O2- atoms to form corner-sharing SiO6 octahedra.

2016年3月7日 · In this study, we established the thermal equation of state (EoS) of the MgSiO 3 post-perovskite phase, which were determined by using both laser-heated diamond anvil cell and density-functional...

2009年1月14日 · 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, polycrystalline aggregates (MgSiO3 perovs...

2015年3月1日 · In this paper we report a computational study of the structural and vibrational properties of the Mg-end members forsterite, wadsleyite and ringwoodite of Mg 2 SiO 4, and akimotoite, majorite and the perovskite phase of MgSiO 3.

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