1.6" Chlorite Included Quartz Crystal Cluster - Peru
This is a 1.6" wide cluster of glassy quartz crystals collected in Peru. I suspect this is a new find as there is very little information on the specific deposit it came out of. The green color of the quartz can be attributed to chlorite inclusions. This specimen has been mounted with mineral tack for museum-quality display.
About Quartz
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.
