Physical properties
Hardness of 7 on the Mohs scale, transparent to translucent with a vitreous luster, trigonal crystal system, and lack of cleavage.
Formation & geological history
Formed through the mechanical weathering and chemical breakdown of pre-existing rocks like granite, accumulating in sedimentary environments over millions of years.
Uses & applications
Used extensively in glass manufacturing, construction as a component of concrete and mortar, and in abrasive sandblasting.
Geological facts
Quartz is one of the most abundant and durable minerals in the Earth's continental crust, able to survive multiple cycles of erosion and deposition.
Field identification & locations
Identified by its high hardness, conchoidal fracture, and resistance to chemical weathering; commonly found in beaches, deserts, and sandstone formations.
