Granodiorite and its mafic microgranular enclaves from the batholith contain characteristic monocrystalline epidotes. Most of these epidotes are idiomorphic, featured frequently with melting corrosion structure and occasionally with allanite-rich cores. The Ps values ((100Fe3+/(Fe3++Al)) of both kinds of epidotes mainly fall between 26 and 28, while TiO2 contents of these epidotes are less than 0.2%. It is suggested that these epidotes are magmatic genesis. The results from petrographic study suggest that the crystallization order in both granodiorite and mafic microgranular enclaves begins with amphibole and epidote, and then comes biotite, plagioclase and other minerals. fix = o ns = "urn:schemas-microsoft-com:office:office" />
