Physical properties
Hardness of 7 on the Mohs scale, clear to translucent color, vitreous luster, hexagonal crystal system when well-formed, and conchoidal fracture with no true cleavage.
Formation & geological history
Formed via the weathering and erosion of parent rocks like granite or sandstone, where resistant quartz grains are transported by water or wind and deposited in sedimentary environments.
Uses & applications
Used extensively in glassmaking, construction as a component of concrete and mortar, and in abrasive sandblasting applications.
Geological facts
Quartz is one of the most abundant and durable minerals in Earth's continental crust, surviving multiple cycles of weathering and sedimentation.
Field identification & locations
Identified by its high hardness (scratches glass) and lack of cleavage, commonly found worldwide in beaches, riverbeds, and sandstone formations.
