Heulandite

Heulandite is the name of a series of tecto-silicate minerals of the zeolite group. Prior to 1997, heulandite was recognized as a mineral species, but a reclassification in 1997 by the International Mineralogical Association changed it to a series name, with the mineral species being named: Heulandite-Ca, Heulandite-Na, Heulandite-K, Heulandite-Sr, Heulandite-Ba (described in 2002).
