About Heulandite-BaHide

Formula:

(Ba,Ca,K)₅(Si₂₇Al₉)O₇₂ · 22H₂O

Colour:

Colourless to white, pale yellowish-white, pale beige

Lustre:

Vitreous, Pearly

Hardness:

3½

Specific Gravity:

2.35

Crystal System:

Monoclinic

Member of:

Heulandite Subgroup > Zeolite Group

Name:

Named according to the IMA recommended nomenclature for the zeolites and its relationship to the other heulandite group minerals. The suffix indicates the predominant extra-framework element; in this case barium. The root name is in honor of Johann Heinrich "John Henry" Heuland [March 21, 1778, Beyreuth, Germany - November 16, 1856, Hastings, Sussex, England, UK], a mineral collector and mineral dealer living in England. Despite having an international reputation, there are no known images of Henry Heuland.

Type Locality:

ⓘ Northern Ravnås Prospect, Vinoren Southern Mines, Vinoren Silver Mine Field, Flesberg, Buskerud, Norway

The barium analogue of Heulandite-Ca, Heulandite-K, Heulandite-Na, and Heulandite-Sr.
