About MogoviditeHide

Formula:
Na9(Ca,Na)12Fe2Zr3Si25O72(CO3) (OH)4
Formula from type description: Na9(Ca,Na)6Ca6(Fe3+,Fe2+)2Zr3◻Si25O72(CO3)(OH,H2O)4
Colour:
Brown to reddish- brown
Lustre:
Vitreous
Hardness:
Specific Gravity:
2.90 - 2.908
Crystal System:
Trigonal
Member of:
Name:
Named for the Моgо-Vid mountain near the type locality.
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.
