Representative micrographs of the solid inclusions observed in minerals of the SBMS: (1) chlorapatite inclusion (outlined in blue) in a sapphirine crystal (reflected light; sample BCOR 68b); (2) anhydrite inclusion in a kornerupine crystal (back-scattered electron image; sample BCOR 72); (3) coalescent anhydrite and chlorapatite inclusions in an Al-bearing enstatite crystal (cross-polarized light; sample NR 94); (4) clinochlore inclusions in aluminous enstatite (plane-polarized light; sample NR 94, modified from F. Foucard, unpublished master thesis, Toulouse, 1997). Abbreviations from Whitney and Evans (2010).
