- Dufrenite with Chalcosiderite and Chalcophyllite
- Miniature, 4.0 x 3.2 x 2.0 cm
- Wheal Phoenix, Minions, Linkinhorne, Cornwall, Liskeard District, England, UK
A nice association from Wheal Phoenix that displays orange, 1mm botryoids of dufrenite on a carpet of dark green, densely crowded, spherical aggregates of chalcosiderite. Veinlets of chalcosiderite transect the gossanous matrix and there are a few minute crystals of chalcophyllite. Dufrenite is a hydrated calcium iron phosphate.
