Physical properties
Hardness of 7 on the Mohs scale, colorless to light pink or white, vitreous luster, hexagonal crystal system, and no true cleavage with conchoidal fracture.
Formation & geological history
Formed through the crystallization of silica-rich magmas or through weathering and deposition in sedimentary environments.
Uses & applications
Used in educational geology kits, comparative mineral studies, and as a primary component in sand for glassmaking and construction.
Geological facts
Quartz is one of the most abundant and durable minerals in the Earth's continental crust, highly resistant to both chemical and physical weathering.
Field identification & locations
Easily identified by its high hardness, lack of cleavage, and resistance to scratching by steel. Common worldwide in soils, riverbeds, and sedimentary rocks.
