Pink quartzite (likely iron-stained)

Quartzite, composed predominantly of quartz (SiO₂)

AI-generated identification · may be incorrect

Massive, coarse-looking and mottled pink, cream, and gray, with a dull to sugary luster; quartz hardness is 7 Mohs and the rock has no cleavage. The image does not show enough detail to confirm mineral grains or composition.

Physical properties

Formation & geological history

Forms when quartz-rich sandstone is recrystallized under heat and pressure, commonly during regional metamorphism; its age depends on the source rock and metamorphic event.

Uses & applications

Used as dimension stone, landscaping and paving material, and sometimes as a decorative or lapidary stone.

Geological facts

Pink hues commonly result from iron-oxide staining or trace minerals; quartzite is generally harder and more resistant to weathering than its sandstone precursor.

Field identification & locations

Look for interlocking quartz grains and a hard, massive texture; unlike sandstone, it typically does not crumble readily. Found worldwide in metamorphic belts, but this specimen’s locality cannot be determined from the image.
