CuFe10Zn2Sb4S13

CuFe10Zn2Sb4S13 is a complex mineral belonging to the tetrahedrite-group minerals. Its chemical formula indicates it is a sulfosalt, containing copper, iron, zinc, antimony, and sulfur. The specific proportions of these elements define this particular member of the tetrahedrite family. These minerals are often found in hydrothermal ore deposits, typically associated with other sulfide minerals. The crystal structure of CuFe10Zn2Sb4S13 is cubic, similar to other tetrahedrites. Its appearance can vary, but it is generally metallic, gray to black in color, and often occurs in massive or granular forms. Due to the presence of copper and iron, it can be of interest in economic geology as a potential source of these metals, though its primary economic significance is usually as an indicator mineral within larger ore bodies. The precise geological conditions under which CuFe10Zn2Sb4S13 forms are related to moderate to low temperatures and specific sulfur fugacities. Its identification in mineralogical studies often relies on X-ray diffraction and electron microprobe analysis due to the complexity of its composition.
