Abstract

The crystal structure of Fe-pumpellyite from Iwakake, Shimobe-cho, Nishiyatsushiro-gun, Yamanashi Prefecture, Central Japan was investigated by a Weissenberg camera combined with a monochromated synchrotron radiation of wavelength 1.000 Å and an imaging plate. Crystallo-graphic parameters are <I>a</I> = 8.884(3), <I>b</I> = 5.899(4), <I>c</I> = 19.292(6) Å, β = 97.49(3)°, <I>A</I>2⁄<I>m</I>. The octahedral X-site is larger than the octahedral Y-site. The obtained constrained occupancy ratios of Fe for the X- and Y-sites are 24% and 18%, respectively, i.e., 40% and 60% of total Fe distribute in the X- and Y-sites, respectively.
