Special issue}, month = {Dec}, note = {P(論文), The olivines from Yamato-74354 (L5-6) and -74371 (H5) meteorites have been studied by X-ray diffraction method. The crystal structures of olivines have been refined using X-ray intensity data. The site preference of metal cations for M1 and M2 sites in both olivine structures has been determined. The cation distributions of Mg^<2+> and Fe^<2+> in M1 and M2 sites for these olivines show a slight tendency to disorder. For Yamato-74354 and -74371 olivines, the distribution coefficient K_D is 1.09 and 0.92,respectively. This tendency resembles the tendency of cation distribution in metamorphic olivines.}, pages = {104--118}, title = {X-Ray Single Crystal Studies of Olivines in Yamato-74354 and -74371 Meteorites}, volume = {17}, year = {1980} }
