stilbite
Sign in to saveAlso known as stilbite-(metal) zeolite series, stilbite series, epidesmine, desmine
Stilbite is the name of a series of tectosilicate minerals of the zeolite group. Prior to 1997, stilbite 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:
