Physical properties
Mohs hardness of 6-7; contains pink or reddish potassium feldspar (orthoclase), translucent quartz, and dark biotite or hornblende; phaneritic texture with visible coarse grains; crystalline luster.
Formation & geological history
Formed by the slow crystallization of magma below the Earth's surface (intrusive) over millions of years, often in continental crust environments.
Uses & applications
Extensively used in construction, architectural facades, countertops, monuments, and as crushed stone for road aggregate.
Geological facts
Granite is one of the most common and recognizable rocks in the Earth's continental crust. Its pink color is specifically due to a high abundance of K-feldspar.
Field identification & locations
Identified by its salt-and-pepper appearance with distinct pinkish crystals. Common in mountain ranges and ancient shield areas. For collectors, look for well-defined large crystal structures.
