Raman imaging as a new approach to identification of the mayenite group minerals.

ABSTRACT: The mayenite group includes minerals with common formula Ca₁₂Al₁₄O_32-x(OH)_3x[W_6-3x], where W = F, Cl, OH, H₂O and x = 0-2. This distinction in the composition is associated with W site which may remain unoccupied or be occupied by negatively charged ions: OH^-, F^-, Cl^-, as well as neutral molecules like H₂O. However, there is no experimental approach to easily detect or differentiate mineral species within the mayenite group. Electron micro-beam facilities with energy- or wavelength-dispersive X-ray detectors, as most common tools in mineralogy, appear to be insufficient and do not provide a definite identification, especially, of hydroxylated or hydrated phases.
