Levyne or levynite is a zeolite mineral, i.e. a hydrated silicate mineral. There are two forms of levyne: Levyne-Na, the sodium dominated form (Na 2,Ca,K 2)Al 2 Si 4 O 12 ·6(H 2 O), and; Levyne-Ca the calcium dominated form (Ca,Na 2,K 2)Al 2 Si 4 O 12 ·6(H 2 O) Levyne crystallizes in the Trigonal - Hexagonal Scalenohedral class. It typically ...

levyne, mineral in the zeolite family, similar in composition and structure to chabazite (q.v.). This article was most recently revised and updated by Amy Tikkanen .

Levyne is an uncommon zeolite, but all occurrences are in cavities of basalt. Associated minerals include erionite, chabazite, phillipsite, natrolite, analcime, thomsonite, and many others.

Levyne-Ca la forma dominada por el calcio Ca,Na 2,K 2)Al 2 Si 4 O 12 ·6(H) 2 O) La levyna cristaliza en la clase escalenoédrica trigonal-hexagonal. Se presenta típicamente en cúmulos radiantes o masas fibrosas, de transparentes a translúcidas, con colores que van del blanco al rojizo y blanco amarillento, pasando por el gris.

It was named in honor of Armand Lévy, …

Of the two original spellings, levyne became the accepted one. The suffix was added in 1997 by the Subcommittee on Zeolites of the International Mineralogical Association to denote the dominant exchangeable cation and distinguish it from the newly named levyne-Na.
