chabazite

(ˈkæbəˌzaɪt)
n
(Minerals) a pink, white, or colourless zeolite mineral consisting of a hydrated silicate of calcium, sodium, potassium, and aluminium in hexagonal crystalline form. Formula: Ca2Al2Si4O12.6H2O
[C19: from French chabazie from Late Greek khabazios, erroneous for khalazios stone similar to a hailstone, from Greek khalazios of hail, from khalaza hailstone + -ite1]
