Physical properties
Hardness of 7 on the Mohs scale, typically translucent to opaque with a vitreous luster and conchoidal fracture.
Formation & geological history
Formed through mechanical weathering and fluvial transport of parent igneous or metamorphic rocks over millions of years.
Uses & applications
Used in landscaping, decorative aggregates, and as raw material for glass production.
Geological facts
Quartz is one of the most abundant and chemically resistant minerals in Earth's continental crust, allowing it to survive long river journeys.
Field identification & locations
Identified by its high hardness, lack of cleavage, and resistance to scratching by steel; commonly found in riverbeds and beaches.
