CaFe23AlFe32SiO43

CaFe23AlFe32SiO43 is a complex silicate mineral. Its chemical formula indicates a high abundance of iron and calcium, with significant aluminum and silicon also present. The structure is characterized by a framework of silicate tetrahedra, with calcium and iron cations occupying interstitial sites. The exact arrangement of these cations and the specific coordination environments of the oxygen atoms contribute to the mineral's overall properties. While definitive crystallographic data for this specific composition might be scarce, minerals with similar complex silicate structures often exhibit variable iron oxidation states, potentially leading to a range of colors from dark brown to black. The presence of multiple cations suggests that CaFe23AlFe32SiO43 might form under specific geological conditions, likely involving high temperatures and pressures, and potentially in environments rich in iron and calcium. Further research would be needed to precisely determine its crystal system, space group, and detailed physical properties such as hardness, density, and cleavage. Its occurrence in natural geological formations would depend on the availability of its constituent elements and the prevailing geochemical processes.
