Abstract

Unknown mineral, which consists mainly Fe, Mg, As, Si, O and H, was found in druse or surface of Loellingite in a skarn mine at the Kiurakozan, Oita Prefecture, Japan. It occurred as a column or fibrous crystal up to 1 mm long in association with scorodite and Arseniosiderite. The composition image of one grain shows two kinds of parts which different in brightness. An electron microprobe analyses of bright and dark parts showed the presence of Fe, Mg, As and Si, and Mg and Si, respectively. The infrared absorption spectrum of mixed powder of bright and dark parts showed OH stretching vibration though no vibrations associated with the carbonate group. The X-ray micro-beam diffraction (PSPC-MDG) data for each part was similar to each other.
