Abstract

The olivine to spinel transformation was analyzed using high-resolution transmission electron microscopy (HRTEM). It was shown by HRTEM structure images of Mg₂GeO₄ olivine deformed under a pressure of 6 GPa at 600 °C, that shear mechanism dominates the transformation. It was found that during the transformation, it is a shear movement that brings the oxygen anions to their positions in the spinel structure. The results show that the Burgers' vector of each dislocation is perpendicular to the anion shear direction.
