Pink Granite

Granite (Alkali-feldspar granite)

Rock Type: igneous

Pink Granite

Physical Properties

Hardness: 6-7 (Mohs); Color: Pink, reddish, white, and grey; Luster: Dull to Vitreous (on crystal faces); Crystal structure: Phaneritic (coarse-grained); Cleavage: Indistinct; Specific Gravity: 2.63-2.75

Formation & Geological History

Formed through the slow crystallization of magma below Earth's surface (intrusive). Composed mainly of potassium feldspar, quartz, and minor mica or amphibole. Often found in continental crust and mountain ranges.

Uses & Applications

Widely used in construction, countertops, floor tiles, monuments, and as ornamental stone or road aggregate.

Geological Facts

The pink color is specifically due to a high concentration of potassium feldspar (orthoclase). Granite is one of the oldest and most abundant rocks on Earth's continental crust.

Field Identification & Locations

Identify by the interlocking crystalline texture and the presence of visible pink feldspar and translucent quartz grains. Found in plutonic formations globally.
