The environment and process of the metamorphism and its melting were examined on the basis of the newly calibrated orthopyroxene-biotite geothermometer and mineralogical and petrological evidences. Opx hornfels consists mainly of orthopyroxene, biotite, cordierite, K-feldspar, and quartz. The hornfels is accompanied in places by leucocratic products which show melt textures consisting mainly of biotite, K-feldspar, plagioclase, and quartz. K-feldspar and quartz occationally contain tiny inclusions of orthopyroxene, biotite, and cordierite, which may have been refractory residues. According to the geological setting, ..., 1999, Includes bibliographical references}, school = {筑波大学, University of Tsukuba}, title = {Granulite metamorphism of pelitic rocks adjacent to the Bushveld complex contact in the Northeastern Transvaal area, South Africa}, year = {2000} }
