Physical properties
Hardness of 7 on the Mohs scale, white to clear color, vitreous luster, conchoidal fracture, specific gravity of 2.65.
Formation & geological history
Formed via weathering and mechanical erosion of primary igneous or metamorphic rocks, subsequently rounded through fluvial or marine transport.
Uses & applications
Used in landscaping, decorative aggregates, filtration systems, and as raw material for glass manufacturing.
Geological facts
Quartz is one of the most abundant and chemically resistant minerals in Earth's continental crust.
Field identification & locations
Easily identified in the field by its high hardness, lack of cleavage, and resistance to scratching by steel.
