Physical properties
Hardness of 7 on the Mohs scale, clear to translucent color, vitreous luster, hexagonal crystal system, and no cleavage.
Formation & geological history
Formed through the weathering, erosion, and transportation of preexisting rocks, primarily granite, over millions of years.
Uses & applications
Widely used in glass manufacturing, construction as concrete aggregate, and in electronics for silicon wafers.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and is exceptionally resistant to weathering.
Field identification & locations
Identified by its high hardness, conchoidal fracture, and lack of reactivity to acid; commonly found on beaches and in riverbeds.
