Osumilite, approximate composition K(Mg,Fe)2 A15SiloO3o, has been reported recently from two granulite localities. The mineral has been synthesised in a model pelitic composition at 1000 and 1100 ~ C and 3.6-6.3 kb under conditions of low water and oxygen fugacity. Osumilite coexists, apparently sta
Coexisting Na-plagioclases from greenschists both in the thermal aureole of the Kasugamura Granite, Japan, and in the low-P metamorphic zone of Yap Island, western Pacific were analyzed in great detail; the peristerite solvus was determined for each suite. The asymmetric solvus has steep albite-rich
