Chabazite was unknown from sedimentary deposits prior to its discovery by Hay (47) in tuffs and tuffaceous clays at Olduvai Gorge, Tanzania. Since then, authigenic chabazite has been recognized in silicic tuffs from Arizona, California, Nevada, and Wyoming (Table II, Figure 3). Most of the occurrences are in lacustrine rocks of late Cenozoic age. There are no reported occurrences of chabazite in rocks older than Eocene in the United States. Monomineralic beds of chabazite are rare, but extensive and nearly pure beds have been reported from lacustrine...
