Physical properties
Hardness of 6-7 on Mohs scale. Composed mainly of quartz, alkali feldspar, and plagioclase with aphanitic to phaneritic crystalline texture.

Formed from the slow cooling of silica-rich magma beneath the Earth's surface over millions of years.
Uses & applications
Widely used in construction, architectural facings, monuments, countertops, and decorative aggregate.
Geological facts
Granite is the most common rock of Earth's continental crust and forms the core of many major mountain ranges.
Field identification & locations
Identify by visible interlocking mineral crystals of quartz and feldspar, often with dark biotite mica flakes. Found globally in continental shields.
