CaAl2Si4O12.6H2O
Hexagonal
Chabazite, a calcium aluminum silicate hydrate mineral of the zeolite group, was reported from Franklin by Frondel (1972) as colorless rhombohedrons associated with stilbite in a vein assemblage.
A remarkable occurrence of chabazite was found in 1990 on the 340 level at Sterling Hill, where it was associated with a Ca-As apatite (possibly johnbaumite), a scapolite (probably meionite), calcite, and a member of the scheelite-powellite series. Chabazite occurs in 1-2 mm crystals, which are colorless, transparent, and notable in that they have a very bright green fluorescence in shortwave ultraviolet radiation. See also Jenkins (1994).
