Zeolites originate through the reaction of volcanic rocks and ash layers with alkaline groundwater. These mineral formations also undergo crystallization in post-depositional settings, taking place over extended periods ranging from thousands to millions of years within shallow marine basins. Natural zeolites, however, are seldom pure and exhibit varying degrees of contamination by other zeolites, quartz, minerals, or metals.
Among the more prevalent mineral zeolites are chabazite, analcime, clinoptilolite, heulandite, stilbite, phillipsite, and natrolite. These diverse zeolite varieties contribute to the geological landscape and are integral components of natural formations shaped by complex processes over extensive timeframes.
