10.2" Galena, Chalcopyrite, Barite and Quartz Association - Morocco

 
 
 
This unique specimen contains hundreds of metallic octahedral and cube-octahedral combination galena crystals, standing out from a sulphide rich, quartz druse coated matrix. This matrix also reveals large amounts of chalcopyrite, indicated by the lustrous red/gold color that's scattered around the specimen. The green color throughout the specimen is likely a result of copper oxidation. There is a small formation of blue barite crystals that formed towards one corner of the specimen.

The back side of this specimen contains many pockets that are filled with quartz druze, as well as a bladed barite cluster, which unfortunately doesn't present well with the assumed presentation layout. Comes with large display stand.

Galena is a lead based mineral that is in fact the primary ore of lead, and has been used for its lead content for thousands of years. Galena typically displays a gray metallic luster and forms cubes or octahedral crystals. The chemical composition of galena is PbS.

Silicon Dioxide, also know 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.
