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:
In the Vinony graph
Within Vinony's link graph, stilbite is referenced by 41 other articles, and connects out to Mohs scale of mineral hardness, refractive index and zeolite.
It is catalogued under topics including Aluminium minerals, Calcium minerals and Minerals in space group 12.
Its subject is documented across 25 Wikipedia language editions.
