About Erionite SubgroupHide

Formula:

M₂[Al₄Si₁₄O₃₆] · 15H₂O

M=Ca, K₂ or Na₂

Lustre:

Silky

Member of:

Zeolite Group

Name:

Named in 1898 by Arthur Starr Eakle from the Greek εριον meaning wool in allusion to the "wooly" appearance of the type material. Erionite was first found at the Durkee Fire Opal Mine, Swayze Creek, Durkee, Baker Co., Oregon (Tschernich, 1992). In modern nomenclature, the original erionite was erionite-Na, but potassium was nearly equal to sodium.

This name now refers to a group of related minerals. Erionite minerals have the average chemical formula Ca3K2Na2[Al10Si26O72].30H2O (Z = 1), whereas the closely related offretite has the average chemical formula CaKMg[Al5Si13O36].16H2O (Z = 1).

NOTE: The zeolite mineral species epitaxially overgrown on lévyne in all cases is identified as erionite (Passaglia et al., 1998).
