Physical properties
Mohs hardness 3.5-5.5, white to clear color, vitreous to pearly luster, and typically forms in cavities with a prismatic or acicular crystal habit.
Formation & geological history
Formed through low-temperature alteration of volcanic glass and ash in alkaline marine or freshwater environments over millions of years.
Uses & applications
Used widely in water purification, ion exchange, agriculture as a soil conditioner, and as a popular specimen for mineral collectors.
Geological facts
Zeolites have a microporous structure that can absorb and release water and other molecules without changing their crystal structure, earning them the nickname boiling stones.
Field identification & locations
Identify by its light-colored crystalline aggregates inside cavities of weathered basalt or volcanic host rocks; common globally in basaltic terranes.
