Pink granite (likely a feldspar-rich granitoid)

Granite, composed mainly of quartz, potassium feldspar, plagioclase, and mica

AI-generated identification · may be incorrect

Coarse-grained and speckled pink-gray with a nonmetallic luster; quartz has Mohs hardness 7, feldspars 6, and mica 2–3. The image shows a rock specimen displayed on a screen, so exact mineral proportions and physical properties cannot be confirmed.

Physical properties

Coarse-grained and speckled pink-gray with a nonmetallic luster; quartz has Mohs hardness 7, feldspars 6, and mica 2–3. The image shows a rock specimen displayed on a screen, so exact mineral proportions and physical properties cannot be confirmed.

Formation & geological history

Granite forms when silica-rich magma cools slowly underground, allowing visible crystals to grow. Such rocks occur in continental crust and range widely in age, from ancient Archean bodies to much younger intrusions.

Uses & applications

Used as building and dimension stone, countertops, paving, monuments, and decorative aggregate; attractive pieces are collected as specimens.

Geological facts

Pink coloration commonly comes from potassium feldspar, while glassy gray grains are often quartz and dark flecks are mica or amphibole.

Field identification & locations

Look for interlocking visible crystals and a mix of pale quartz/feldspar with dark minerals; common in continental batholiths worldwide. The displayed image is insufficient to verify that this is granite rather than another pink granitoid.
