Physical properties
Hardness of ~7 on Mohs scale, grayish-pink to tan color, granular texture often smoothed by water action, massive structure without prominent cleavage.
Formation & geological history
Formed from quartz-rich sandstone subjected to heat and pressure. Later weathered, transported, and rounded by river or glacial action.
Uses & applications
Primarily decorative in this form, used in landscaping or tumbling for collectors.
Geological facts
Quartzite is extremely durable, which is why it often survives transport in rivers and glaciers to form smooth, rounded pebbles.
Field identification & locations
Identify by its hardness (scratches glass) and granular but fused texture. Very common in riverbeds, glacial deposits, and beaches globally.
