About Hydroxyapophyllite-(K)Hide

KCa4(Si8O20)(OH,F) · 8H2O
4 - 5
Crystal System:
Apophyllite was named in 1806 by Rene Just Haüy from the Greek for "away from" (ἀπό, apo) and "leaf" (φύλλον, phyllos), in allusion to the way it exfoliates upon heating. Chemical variants were recognized by Pete J. Dunn, Roland C. Rouse, and Julie A. Norberg in 1978.
Fluorapophyllite-(K)-Hydroxyapophyllite-(K) Series.

Mineral name changed from apophyllite-(KOH) to hydroxyapophyllite-(K) (Hatert et al. 2013)

Classification of Hydroxyapophyllite-(K)Hide


9 : SILICATES (Germanates)
E : Phyllosilicates
A : Single nets of tetrahedra with 4-, 5-, (6-), and 8-membered rings
