Physical properties
Hardness of 7 on the Mohs scale, pink to reddish color, vitreous luster, non-foliated granular structure, specific gravity around 2.65.
Formation & geological history
Formed from quartz-rich sandstone subjected to intense heat and pressure during tectonic metamorphism over millions of years.
Uses & applications
Used in construction, as crushed stone for roads, for decorative landscaping, and occasionally carved into ornamental objects.
Geological facts
Quartzite is extremely durable and resistant to weathering, often forming prominent mountain ridges where softer rocks erode away.
Field identification & locations
Identified by its sugary texture, inability to be scratched by a steel knife, and lack of fizz when tested with acid. Found globally in ancient mountain belts.
