Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, conchoidal fracture, and hexagonal crystal system when unweathered.
Formation & geological history
Formed through the weathering and prolonged aqueous transportation of igneous or metamorphic rocks.
Uses & applications
Used in landscaping, decorative gravel, glassmaking, and abrasive manufacturing.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust and is exceptionally resistant to weathering.
Field identification & locations
Easily identified by its high hardness, lack of cleavage, and resistance to acid; commonly found in riverbeds and beaches worldwide.
