CaAl2Si2O8 · 4H2O
Member of:
The root name is for Carlo Giuseppe Gismondi (1762-1824), Italian mineralogist, who previously discovered "zeagonite" - a mixture of gismondine and phillipsite. The suffix denotes the dominant extra-framework cation.
At present (2006) the name approved by IMA CNMNC (after Zeolites Subcommittee) is simply gismondine.
All gismondines found and studied over almost two centuries were calcium-dominant.
Recently, a barium-dominant gismondine, "gismondine-Ba" has been discovered in slag material (of course not approved, as valid species, by IMA CNMNC). Therefore, in keeping with the recommendation of the Zeolite Subcommittee, "gismondine" acquired the status of series, and any individual species has to be denoted now with the suffix for the dominant extra-framework cation (e.g., gismondine-Ca, gismondine-Ba).
