Scorodite

Field of view: 5 mm. Scorodite associated with löllingite. The fine grains with a vitreous luster are scorodite. The translucent white basement is gangue quartz. The massive silver-white parts are löllingite.

Recovered from an open space of a quartz vein in a meteoric oxidation zone of a pneumatolytic deposit formed near the boundary between welded tuff and S-type (Ilmenite-series) granite, members of a caldera complex.

Scorodite from this location was described in 1972.
