Electron Backscatter Diffraction (EBSD)
OIM orientation and phase maps from a granite sample with multiple K-bearing minerals present.
Orientation Map
Magnetite - Fe3O4
Albite - NaAlSi3
Microline - KAlSi3O8
Phase Map
Quartz - SiO2
Biotite K (Fe, Mg)3AlSi3O10(F, OH)2
Albite and Microline are both triclinic phases.
