Physical properties
Hardness of 7 on the Mohs scale, transparent to translucent with a vitreous luster, and a trigonal crystal system.
Formation & geological history
Formed through the mechanical and chemical weathering of primary igneous rocks like granite, followed by transport and deposition.
Uses & applications
Used primarily in geological studies, sedimentology, and as a raw material in glassmaking and construction industries.
Geological facts
Quartz is one of the most abundant and durable minerals in Earth's continental crust, surviving multiple cycles of erosion.
Field identification & locations
Identified by its high hardness, lack of cleavage, and resistance to chemical weathering; commonly found in beaches and sandstone.
