Abstract A petrogenetic grid and related diagrams derived from KFMASH‐system experiments demonstrate that osumilite is stable in relatively magnesian bulk rock compositions ( X Mg > 0.6) at temperatures in excess of 875° C and pressures less than 11 kbar. The experiments, involving the dehydratio...
