Abstract
Osumilites from Sakkabira, Japan, Obsidian Cliffs, Oregon, and Nain, Labrador have been studied by optical, infrared, and Mössbauer spectroscopy. Osumilite is an anhydrous mineral. A major proportion of the Fe^(2+) occurs in the channel-like cavities. Biaxial Nain osumilite is X-ray hexagonal, and does not show infrared spectroscopic evidence for Al/Si ordering. The biaxiality arises from the channel contents.

Wayne Dollase (University of California, Los Angeles) took the Mössbauer spectra used in this study and fitted the spectrum of the Obsidian Cliffs sample. Jonathan Berg (Northern Illinois University) provided the Nain osumilite, Gordon Brown (Stanford University) provided the crystals of the Sakkabira osumilite and several discussions concerning osumilite crystal chemistry, and Jack Huneke (California Institute of Technology) provided Obsidian Cliffs osumilite. Portions of this research were supported by NSF Grant EAR76-02014.Additional details
