Zeolites from the most important volcanoclastic deposits of Italy include: (1) phillipsite and heulandite from the cinerite of the central northern Apennines; (2) chabazite and phillipsite from phonolitic tephritic ignimbrites contg. black pumices; (3) phillipsite from the tufo lionato of Vulcano Laziale; (4) chabazite and phillipsite from the Campanian ignimbrite; (5) phillipsite from the Neapolitan yellow tuff; and (6) chabazite and phillipsite from the pyroclastics of Monte Vulture. Compared with sedimentary phillipsites and chabazites described in the literature, the chabazites and phillipsites studied have lower Si/Al ratios and higher K contents. These chem. peculiarities are correlated with both the K-rich vesuvianitic-leucititic, ...
