  • Gmelinite: The zeolite mineral gmelinite information and ...

    www.minerals.net/mineral/gmelinite.aspx Calcium-dominating Gmelinite is called Gmelinite-Ca, and is the most prevalent form of this series. Sodium-dominating Gmelinite, defined as Gmelinite-Na, and potassium-dominating Gmelinite, defined as Gmelinite-K, are both rare. Most Gmelinite specimens in collections are Gmelinite-Ca.
