Introduction

　　Mainly composed of copper, antimony and sulphur, tetrahedrite often contains iron, zinc and occasionally small amounts of silver, lead and mercury. It shares the same crystal structure with tennantite （Tennantite, Cu12As4S13）. Both belong to a solid solution series. Antimony-rich specimens are tetrahedrite while arsenic-rich ones are tennatite.

　　Tetrahedrite is characterized in its metallic luster, gray to black colors and brittleness. It is one of the most common sulfosalts, often formed in low-temperature to mid-temperature hydrothermal veins. Tetrahedrite is used as an ore of copper and silver.
