About Erionite-CaHide

Formula:

(Ca,K2,Na2)2[Al4Si14O36] · 15H2O

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. Levinson Rule suffix added in allusion to Ca dominant exchangeable cations.

A zeolite difficult to distinguish from offretite.
