Abstract

Fe-rich prehnite from Mitsu, Shimane, Japan, was studied using 57Fe Mössbauer spectroscopy and X-ray Rietveld method. Prehnite shows two modes of occurrence: a druse mineral (Prh I) and a replacement of primary plagioclase (Prh II). The Fe contents of Prh I and II are 0.33-0.44 and 0.01-0.46 apfu, respectively. All Fe in Prh II is ferric whereas Prh I contains small amount of Fe2+ in addition to major Fe3+. According to structural refinements with Pmna and Pma2 space groups, the fitting with Pma2 gave more reduced reliability factors, implying ordering of Al and Si at the T2 sites.
