    Characterization of a (021) twin in coesite using LACBED and precession electron diffraction

    Coesite is a high-pressure polymorph of silica stable in the pressure range 2.5–9 GPa, which corresponds to a minimum depth in Earth of ca. 90 km. Given the ubiquity of silica at the surface of the Earth, coes...

    Precession Electron Diffraction for the characterization of twinning in pseudo-symmetrical crystals: case of coesite

    Recent developments in electron diffraction call for a reappraisal of the possibilities offered by spot patterns. Among them is the Vincent-Midgley Precession Electron Diffraction (PED) technique [1], which re...

    Deformations in Minerals

    Minerals submitted to tectonic stresses may deform plastically, i.e., continuously at the lattice scale. Various mechanisms of plastic deformation may be involved, depending on several parameters, e.g., temper...
