Physical properties
Hardness: 7 on Mohs scale; Color: White to translucent; Luster: Vitreous; Crystal Structure: Trigonal; Cleavage: None
Formation & geological history
Formed through crystallization in igneous and metamorphic environments, later weathered, transported, and rounded by water action in sedimentary environments.
Uses & applications
Used in landscaping, decorative stone, abrasive manufacturing, and glassmaking.
Geological facts
Quartz is one of the most abundant and durable minerals in the Earth's continental crust, highly resistant to both chemical and mechanical weathering.
Field identification & locations
Easily identified by its high hardness (scratches glass) and lack of cleavage. Commonly found in riverbeds, beaches, and glacial outwash.
