Member of:
Name:
Named for Carlo Giuseppe Gismondi (1762-1824), Italian mineralogist, who previously discovered "zeagonite" - a mixture of gismondine and phillipsite.
Zeolite Group.
"Gismondine-Ba" (proposed) has been found naturally as a secondary slag mineral on lead-rich slags. All other Gismondine is the calcium-rich member, for which "Gismondine-Ca" has been proposed.
