Formula:

KCaMg(Si13Al5)O36 · 15H2O

Name:

Named in honor of Albert Jules Joseph Offret (24 October 1857, Douai, France - 4 March 1933, Lyon, France), professor at the University of Lyon, France.

Zeolite Group.

A zeolite difficult to distinguish from erionite.

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