Abstract: Inclusions of the kyanite K-feldspar quartz apatite and kyanite garnet K-feldspar quartz assem-blages of the prograde metamorphic stage and the sillimanite garnet K-feldspar quartz and sillimanite gar-net K-feldspar quartz apatite assemblages of the peak metamorphic stage were identified by laser Raman spectroscopy in zircons from the khondalite series in south-central Inner Mongolia.These data indicate that the mineral assemblages and P-T path of khondalites series experienced transformation from the kyanite sta-bility field to sillimanite stability field.
