• Voronkovite - Wikipedia

    en.wikipedia.org/wiki/Voronkovite Voronkovite is a very rare mineral of the eudialyte group with the formula Na 15 (Na,Ca,Ce) 3 (Mn,Ca) 3 Fe 3 Zr 3 Si 2 Si 24 O 72 (OH,O) 4 Cl·H 2 O. The formula is based on the simplified original one; it does not show the presence of cyclic silicate groups, but two M3- and M4-site silicon atoms are shown separately (basing on the nomenclature of the eudialyte group). ...
