About Ferrierite-KHide

Walter F. Ferrier
Formula:
(K2,Na2,Mg,Ca)3-5Mg[Al5-7Si27.5-31O72] · 18H2O
Lustre:
Vitreous
Hardness:
3 - 3½
Crystal System:
Orthorhombic
Name:
Named in 1997 by Coombs et al., during a reorganization of zeolite species, for being potassium-dominant ferrierite. The root name is for Walter Frederick Ferrier [4 May 1865 Montréal, Québec, Canada – 15 November 1950 Toronto, York County, Ontario, Canada], mineralogist, mining engineer, and geologist with the Geological Survey of Canada.
