Pink granite
Granite, composed chiefly of quartz, potassium feldspar, and plagioclase, with minor dark minerals
AI-generated identification · may be incorrectCoarse-grained, interlocking crystals; pink feldspar, gray-white quartz, and dark flecks. Typical hardness is about 6–7 Mohs, with a vitreous-to-dull luster and no consistent cleavage in the rock as a whole.

Physical properties
Coarse-grained, interlocking crystals; pink feldspar, gray-white quartz, and dark flecks. Typical hardness is about 6–7 Mohs, with a vitreous-to-dull luster and no consistent cleavage in the rock as a whole.
Formation & geological history
Forms when silica-rich magma cools slowly underground, commonly within continental crust. Individual granite bodies can be hundreds of millions to billions of years old; the image alone cannot establish age.
Uses & applications
Widely used as dimension stone, countertops, paving, monuments, and decorative aggregate; polished slabs are also collected.
Geological facts
The visible pink and gray patches are mineral grains, not layers, and the grain size reflects slow cooling at depth.
Field identification & locations
Identify it by its interlocking coarse grains, quartz, and abundant pink feldspar; common worldwide in continental mountain belts and ancient cratons. The image appears to show a granite surface or pattern, so specimen scale and provenance are unknown.
