1. (Minerals) any of a large group of glassy secondary minerals consisting of hydrated aluminium silicates of calcium, sodium, or potassium: formed in cavities in lava flows and plutonic rocks
2. (Chemistry) any of a class of similar synthetic materials used in ion exchange and as selective absorbents. See molecular sieve
