 note = {P(論文), Staurolite is found as inclusions in garnet in a corundum-garnet gneiss from an outcrop of two-pyroxene gneiss in the eastern Sør Rondane Mountains. The staurolite is a zinc-poor variety of normal iron content (ZnO=0.10-0.32wt%; X_<Fe>=0.74-0.80), and occurs only in 'domains', consisting mainly of plagioclase, enclosed in the zoned garnet with magnesian cores (X_<Fe>=0.69-0.70). From textural and mineralogical observations, it is possible to distinguish (1) a staurolite-bearing mineral association in the domains and (2) a granulite-facies association of the garnet core with the matrix constituents plagioclase, biotite, sillimanite, corundum. spinel, magnetite and ilmenite. In addition, compositional relations between staurolite and the association garnet-corundum-spinel-sillimanite is consistent with the prograde reaction staurolite=garnet+corundum+spinel+sillimanite+H_2O. On the basis of textural features and paragenetic relations, staurolite in this gneiss is interpreted to be a relic that was isolated from the matrix by growing of garnet in a prograde metamorphic process attaining the granulite facies. A later, probably amphibolite-facies metamorphic episode is suggested by Fe-Mg redistribution between garnet and biotite in direct contact.},
