• Mogovidite - Wikipedia

    en.wikipedia.org/wiki/Mogovidite Mogovidite is a very rare mineral of the eudialyte group, with formula Na 9 (Ca,Na) 6 Ca 6 (Fe 3+,Fe 2+) 2 Zr 3 []Si(Si 9 O 27) 2 (Si 3 O 9) 2 (CO 3)(OH,H 2 O) 4. The formula given is based on the original one but extended to show the presence of cyclic silicate groups. It is similar to feklichevite, differing from it in the presence of essential vacancies (at the M3 site) and carbonate group.

    www.mindat.org/show.php Nb-deficient carbonate analogue of Feklichevite. Unique chemistry, although similar to that of golyshevite (which however is Nb-bearing in addition to Na-Ca-Zr-Fe-Si-C). One of characteristic features is dominance of ferric iron - a feature shared with other members of the group: fengchengite, feklichevite, and ikranite.As in fengchengite, vacancy is essential in one of the sites.
