Osarizawaite

Field of view: 15 mm. Earthy osarizawaite. The earthy green parts are groups of fine osarizawaite crystals. The white host is gangue quartz.

Recovered from an open space of a quartz vein in a meteoric oxidation zone of a moderate-temperature hydrothermal deposit in andesitic pyroclastics formed by dacite probably associated with volcanic activity of a caldera.

Osarizawaite from this location was described in 1970.
