Physical properties
Hardness of 7 on the Mohs scale, tan to brown color, vitreous to greasy luster, massive crystal structure, and specific gravity around 2.65.
Formation & geological history
Formed from the thermal or regional metamorphism of quartz sandstone under high temperatures and pressures over millions of years.
Uses & applications
Used primarily in landscaping, construction aggregates, and as a decorative stone in gardens.
Geological facts
Quartzite is extremely resistant to weathering, which explains why quartz pebbles often survive long transport in rivers to become smooth and rounded.
Field identification & locations
Identify it by its high hardness that scratches glass, lack of effervescence with acid, and granular quartz texture. Commonly found in riverbeds and ancient alluvial deposits worldwide.
