Physical properties
Hardness: 7, Color: white to grey, Luster: vitreous, Crystal structure: granular, Cleavage: none, Specific gravity: 2.6-2.8
Formation & geological history
Formed from the metamorphism of quartz sandstone under high heat and pressure.
Uses & applications
Used in construction, landscaping, and as a decorative stone.
Geological facts
Quartzite is often confused with marble but is much harder and will not fizz in contact with acid.
Field identification & locations
Identify by its hardness (scratches glass), grainy texture, and lack of cleavage. Common in areas with past tectonic activity.
