Physical properties
Hardness of 7 on the Mohs scale, white to clear color, vitreous luster, trigonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Formed through the accumulation and transportation of weathering-resistant quartz grains in sedimentary environments over millions of years.
Uses & applications
Used in landscaping, decorative filler, abrasives, and as a raw material for glassmaking and electronics.
Geological facts
Quartz is one of the most abundant and durable minerals in Earth's continental crust, surviving weathering processes that destroy other minerals.
Field identification & locations
Identified by its high hardness, lack of cleavage, and resistance to acid; commonly found in riverbeds, beaches, and conglomerate rock formations.
