We have investigated the microstructure of naturally deformed olivine (chemically
equilibrated at 1000° C) by conventional transmission electron microscopy and electron …

In this work, we investigate twist grain boundary (GB) energies and structures in Mg 2 SiO 4
forsterite using atomistic simulations. We first present a new bond orientational order …

This work compares the mechanical properties of two geomaterials: forsterite and
magnesite. Various physical conditions are considered to investigate the evolution of stress …

Five different interatomic potentials designed for modelling forsterite Mg 2 SiO 4 are
compared to ab initio and experimental data. The set of tested properties include lattice …

Olivine with chemical composition (Mg, Fe) 2SiO4 is a silicate which is supposed to strongly
constrain the flow of the Earth's upper mantle under thermal convection. Its mechanical …

A transition from A-type to E-type fabrics in olivine may be the cause of a decrease in
seismic anisotropy with depth in the upper mantle. To better understand upper mantle …

Although recent studies have investigated He behavior in undeformed mantle minerals, the
effect of defects generated by plastic deformation on He storage and transport remains …

In this study, we report atomistic calculations of the core structure of screw dislocations with
[001] Burgers vector in Mg2SiO4 olivine. Computations based on the THB1 empirical …

Mineral carbonation contributes to CO2 reduction, and it may also reduce the cost of mineral
processing by improving the mechanical properties of rock/ore. Here, we study and compare …

Water can be incorporated into the lattice of mantle minerals in the form of protons charge-
balanced by the creation of cation vacancies. These protonated vacancies, when they …
