Physical properties

Hardness of 7 on the Mohs scale, typically colorless or white, vitreous luster, and conchoidal fracture.

Formation & geological history

Formed through the weathering and erosion of quartz-rich rocks like granite, subsequently transported and deposited by water or wind.

Uses & applications

Extensively used in glassmaking, construction as a component of concrete, sandblasting, and electronics.

Geological facts

Quartz is one of the most abundant and durable minerals on Earth's continental crust, surviving multiple cycles of weathering.

Field identification & locations

Found abundantly in beaches, deserts, and riverbeds worldwide; identified by its high hardness and resistance to chemical weathering.
