1.6" Fibrous Mineralization (Roselite?) on Quartz - Morocco
This specimen contains a fibrous mineralization, likely roselite, encrusting an aggregation of quartz crystals. The quartz formed from a pink dolomite rich matrix. This specimen was collected from the Bou Azer District of Morocco.
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.
