Physical properties
Hardness of 7 on the Mohs scale, typically white, gray, or tan in color with a vitreous to dull luster.
Formation & geological history
Formed through the mechanical weathering and prolonged aqueous transport of larger quartz-bearing rocks in river or marine environments.
Uses & applications
Used in landscaping, decorative gravel, and as aggregate in construction.
Geological facts
Quartz is one of the most abundant and weather-resistant minerals on Earth's surface.
Field identification & locations
Identified by its high hardness, lack of cleavage, and smooth, water-worn shape found abundantly in gravel bars and beaches.
