· 2.1.4. Electron Back-Scatter Diffraction (EBSD) Since the technique first emerged in the mid-1990’s, EBSD [ 50, 51, 52] has found wide application in mineralogy, with particular suitability to more refractory phases, such as zircon and garnet. Among the ore minerals, pyrite has been a major focus.
