About Gmelinite Subgroup
Member of:
Name:
Gmelinite was named for the German chemist and mineralogist Christian Gottlob Gmelin (1792-1860).
In 1997, gmelinite was split into Gmelinite-Ca, Gmelinite-Na and Gmelinite-K.
Gmelinite was originally described from Montecchio Maggiore, Vicenza Province, Veneto, Italy and Little Deerpark Quarry, Glenarm, Co. Antrim, Northern Ireland, UK.
