Locality type:Quarry
Classification
Species:Heulandite-Na
Formula:(Na,Ca,K)6(Si,Al)36O72 · 22H2O
Comments:The measured Si:Al ratio ranges between ~3.5:1 and ~4:1 (analyses on crystal faces) and thus straddles, for the Si-richest compositions, the boundary between heulandite-Na and clinoptilolite-Na.
