About HydrokenoralstoniteHide

Colourless, white
Specific Gravity:
2.56 - 2.62
Crystal System:
Named after Rev. J. Grier Ralston (December 28, 1815 - November 10, 1880), of Norristown, Pennsylvania, USA, who first observed the mineral.
Renamed from ralstonite after being moved into the Pyrochlore Supergroup (IMA July 2016; Atencio et al., 2017).
The earlier reported "AHF" phase (hydrated aluminum hydroxy-fluoride) and the "ralstonite-like mineral" (Desborough & Rostad, 1980; Keith, 1991; Rosenberg 2006) are also hydrokenoralstonite.

Compare UM1990-21-F:AlCaHMgNa and UM1941-01-F:AlCaHMgNa.

Classification of HydrokenoralstoniteHide

Approved, 'Grandfathered' (first described prior to 1959)
