Beraunite from
State Forest Quarry #2 (State Forest No. 2 Mica Mine), Cobalt, East Hampton (Chatham), Middlesex Co., Connecticut, USA

Formula:Fe2+Fe53+(PO4)4(OH)5 · 6H2O
Comments:reported by Dick Schooner, no details in the reference. Identified by Van King from posted photographs but an XRD test made in the National Museum Prague (dr. Jiri Sejkora) of the green material with some matrix found "no beraunite but something similar to messelite" and apatite, which are the matrix species.
Habit:radiating acicular crystals in micro hemisperical aggregates
Colour:green, but may just be a thin coating of something on messelite
References:Januzzi (1976) p.234-5.
