Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, conchoidal fracture, and typically brown to clear in color.
Formation & geological history
Formed via the weathering and aqueous transportation of larger quartz-bearing rocks over extended geological timescales.
Uses & applications
Used in landscaping, decorative aggregates, and as a raw material in glassmaking and abrasives.
Geological facts
Quartz is one of the most abundant and durable minerals in Earth's continental crust, highly resistant to chemical weathering.
Field identification & locations
Identified by its high hardness, lack of cleavage, and smooth, water-worn shape found abundantly in riverbeds and beaches.
