The rodingites appearing as vein with width of 30-70cm and extension of about 10m in a zone intercalated between serpentinite and granodiorite in the western part of Kyuragi-machi, Saga Prefecture were examined microscopically and by means of X-ray diffraction. The results obtained by inspection of the transitional parts between rodingite and granodiorite suggest that prior to intrusion of granodiorite the former might have been produced between serpentinite and schist. As for hydrogrossular found in the rodingites, its values of d_<420> indicate a variation from 2.66_2-2.66_3 A recognized in the specimens obtained near the contact with serpentinite to 2.65_0-2.65_1 A near that of granodiorite. On the other hand, the components of albite are more abundant near the side of granodiorite and those of amphibole are observed as alteration products.
