CaNaMgFe2AlSi2O6

CaNaMgFe2AlSi2O6 is a mineralogical formula representing a complex silicate. While no officially recognized mineral name corresponds directly to this exact chemical composition, it points to a member of the pyroxene or amphibole group, or potentially a related silicate structure. The formula indicates the presence of calcium (Ca), sodium (Na), magnesium (Mg), iron (Fe), aluminum (Al), silicon (Si), and oxygen (O) in specific ratios. Iron can exist in both ferrous (Fe2+) and ferric (Fe3+) states, which would influence the precise stoichiometry and properties of any resulting mineral.

The arrangement of these elements within a crystal lattice would determine the mineral's specific properties, such as its hardness, color, cleavage, and density. Silicates with such a diverse range of cations are common in igneous and metamorphic rocks. For instance, minerals like augite, hedenbergite, or certain amphiboles share some of these constituent elements, though their proportions and structural arrangements differ. The presence of both Na and Ca suggests a potential for solid solution series with other minerals. Further crystallographic and chemical analysis would be required to definitively identify a specific mineral or mineral group associated with this formula.
