Quartz Cluster with Iron and Manganese - Diamond Hill

This small quartz cluster from Diamond Hill, South Carolina, is covered in a thin manganese and iron oxide coating.

Silicon Dioxide, also known as SiO2 or Quartz, is the second most abundant mineral in the Earth's crust. Quartz crystals generally grow in silica-rich, hot watery solutions called hydrothermal environments, at temperatures between 100°C and 450°C, and usually under very high pressure. Quartz veins are formed when open fissures are filled with hot water during the closing stages of mountains forming, and can be hundreds of millions of years old.
