Pink Granite

Hardness: 6-7 on Mohs scale. Color: Pale pink to reddish with grey, green, and white quartz/feldspar veins and inclusions. Luster: Dull to earthy on weathered surfaces, pearly to vitreous on fresh fractures. Crystal structure: Phaneritic (medium- to coarse-grained interlocked crystals). Cleavage: Poor in mass, individual feldspars show prominent cleavage planes. Specific gravity: ~2.63-2.75.

Formed by the slow cooling and crystallization of felsic magma deep beneath the Earth's surface (plutonic setting). The pink coloration comes from potassium-rich orthoclase feldspar, while dark veinlets are secondary mineral infills along micro-fractures.

Widely used as dimension stone, crushed stone for construction, aggregate, road base, river rock for landscaping, and decorative garden boulders.

Pink granite is the state rock of Wisconsin. Famous formations include the Llano Uplift in Texas and the Precambrian granites of the Canadian Shield.

Identified by its pink potassium feldspar matrix, visible quartz grains, coarse crystalline texture, and high hardness (scratches glass). Commonly found in continental crust areas, glacial till, and riverbeds.
