Heulandite

Q: What is Heulandite made of?

Heulandite has the chemical formula (Ca,Na)₂₋₃Al₃(Al,Si)₂Si₁₃O₃₆·12H₂O, crystallises in the monoclinic system and measures 3.5 – 4 (Mohs) on the Mohs scale. Heulandite is a calcium-rich zeolite that crystallises inside vesicles of altered basaltic lava when hot, silica- and alumina-bearing groundwater percolates through the rock. Its layered aluminosilicate framework contains channels wide enough to hold loosely bound water molecules and exchangeable cations, giving the zeolite family its characteristic ability to dehydrate and rehydrate without structural collapse. The pearly lustre on the perfect (010) cleavage is diagnostic.
