Switzerite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
(Mn,Fe)3(PO4)2 · 7H2O
Colour:
Pale pink, pinkish brown
Lustre:
Pearly
Hardness:
2
Crystal System:
Monoclinic
Name:
Named by John S. White and Peter B. Leavens in 1967 in honor of George Shirley Switzer (11 June 1915 Petaluma, California, USA - 23 March 2008), Curator of Minerals, US National Museum (Smithsonian Institution), Washington D.C., USA.

In 1986, White, Leavans, and Pier F. Zanazzi redefined switzerite and renamed the original type material as metaswitzerite.
Ludlamite Group.

Switzerite rapidly and irreversibly dehydrates in air within minutes to Metaswitzerite which contains only 4 water molecules per formula unit. All "switzerites" in collections should be considered metaswitzerites, unless there is some analytical evidence to the contrary.
