Foggite from Palermo mine, Groton, Grafton Co., New Hampshire, United States
Creamy balls composed of platy crystals to 1mm. Foggite was first described by Paul Moore, a renowned expert on Palermo and phosphate, in 1975. Foggite, named after Forrest Fogg, can be confused with Crandallite or Fairfieldite. The best crystals occur as fans of plates much like an open book. .
