Примечания

The mineral name was used for a sample later shown to be duftite. So the name was discredited. Vésignié J P L (1935) Présentation d'échantillons. Bulletin de la Société Française de Minéralogie 58, 4-5 The name was reintroduced when a piece matching the original definition was discovered: Bideaux R A, Nichols M C, Williams S A (1966) The arsenate analog of tsumebite, a new mineral.
