Physical properties
Hardness of 7 on the Mohs scale, typically white or translucent, vitreous luster, trigonal crystal system, and lacks cleavage.
Formation & geological history
Formed through the weathering and prolonged aqueous transport of parent igneous or metamorphic rocks over millions of years.
Uses & applications
Used in landscaping, decorative gravel, abrasive manufacture, and as aggregate in concrete production.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits strong piezoelectric properties.
Field identification & locations
Easily identified by its high hardness, conchoidal fracture, and resistance to chemical weathering in stream beds.
