Pink Granite

Physical Properties

Hardness: 6-7 on Mohs scale; Color: Pink, salmon, or peach with black highlights; Luster: Dull to vitreous; Crystal Structure: Phaneritic (large, visible crystals); Specific Gravity: 2.63 - 2.75.

Formation & Geological History

Formed from the slow cooling and crystallization of molten magma deep beneath the Earth's surface (plutonic). Most granites date from the Precambrian or Paleozoic eras.

Uses & Applications

Extensively used in construction for countertops, floor tiles, paving stones, and memorial monuments due to its durability and aesthetic appeal.

Geological Facts

The pink color is caused by an abundance of potassium feldspar (orthoclase). Granite makes up a large portion of the Earth's continental crust and is often found in the core of mountain ranges.

Field Identification & Locations

Identify in the field by its speckled 'salt and pepper' appearance and interlocking crystals of pink, white, and black. Common in batholiths and shield areas like the Llano Uplift in Texas or the Scottish Highlands.
