Physical properties
Hardness: 6-7 on Mohs scale. Color: Pink, salmon-orange, with grey and black specks. Luster: Vitreous to dull. Structure: Phaneritic (coarse-grained). Cleavage: Imperfect. Specific Gravity: 2.63-2.75.
Formation & geological history
Formed through the slow crystallization of magma below Earth's surface. This specimen appears to be from a plutonic environment, likely Precambrian or Paleozoic in age, typical of mountainous regions in the Western US.
Uses & applications
Primarily used in construction for countertops, floor tiles, paving stone, monuments, and as architectural aggregate.
Geological facts
The pink color is caused by an abundance of potassium feldspar (orthoclase). Granite makes up much of the continental crust.
Field identification & locations
Identify by its interlocking coarse crystals of pink feldspar, clear quartz, and dark mica or hornblende. Commonly found in large batholiths and mountain ranges.
