1.9" Chlorite Quartz Crystal Cluster - Pakistan
This is a cluster of quartz crystals that was collected from the Balochistan Region of Pakistan. The green color of the quartz can be attributed to chlorite coating most of the cluster.
Quartz is the name given to silicon dioxide (SiO2) and is the second most abundant mineral in the Earth's crust. Quartz crystals generally grow in silica-rich environments--usually igneous rocks or hydrothermal environments like geothermal waters--at temperatures between 100°C and 450°C, and usually under very high pressure. In either case, crystals will precipitate as temperatures cool, just as ice gradually forms when water freezes. Quartz veins are formed when open fissures are filled with hot water during the closing stages of mountain formation: these veins can be hundreds of millions of years old.
