Physical properties
Hardness of 7 on the Mohs scale, white to translucent color, vitreous luster, conchoidal fracture, and specific gravity around 2.65.
Formation & geological history
Formed through the weathering and prolonged aqueous transportation of parent rocks, highly resistant to chemical and physical breakdown.
Uses & applications
Used in landscaping, decorative aggregates, and occasionally as raw material for glass manufacturing.
Geological facts
Quartz is one of the most abundant and durable minerals on Earth's continental crust, frequently surviving multiple cycles of erosion and deposition.
Field identification & locations
Easily identified by its high hardness, lack of cleavage, and resistance to scratching by steel; commonly found in riverbeds, beaches, and conglomerates worldwide.
