Pink Granite

Physical Properties

Hardness: 6-7 on Mohs scale; Color: Pink, salmon, white, and grey; Luster: Vitreous to dull; Crystal structure: Phaneritic (coarse-grained) with visible crystals; Specific gravity: 2.63 - 2.75.

Formation & Geological History

Formed from the slow crystallization of magma below the Earth's surface in continental crust environments. This specimen specifically shows high levels of Potassium Feldspar (Orthoclase), which provides the pink hue.

Uses & Applications

Widely used in construction, countertops, monuments, flooring, and as crushed stone for aggregate.

Geological Facts

Granite is the most common rock in Earth's continental crust. The pink color is usually due to an abundance of potassium feldspar rather than impurities.

Field Identification & Locations

Identify in the field by its 'salt and pepper' appearance (though pink here), visible interlocking crystals, and extreme hardness (it will easily scratch glass). Common in mountainous or eroded shield areas.
