  • Heulandite: The zeolite mineral heulandite information and ...

    www.minerals.net/mineral/heulandite.aspx Calcium-dominating Heulandite is called Heulandite-Ca, and is by far the most prevalent form of this series. Sodium-dominating Heulandite is the next most common, and is known as Heulandite-Na, followed by potassium-dominating Heulandite known as Heulandite-K. Strontium-dominating Heulandite is known as Heulandite-Sr, and is very uncommon.
