Physical properties

Hardness of 6 on the Mohs scale, coarse-grained texture, composed primarily of quartz, alkali feldspar, and plagioclase. Displays a phaneritic crystal structure with vitreous luster.

Formation & geological history

Formed from the slow crystallization of magma below Earth's surface over millions of years. Common in continental crust worldwide.

Uses & applications

Widely used in construction, countertops, monuments, and architectural facings due to its high durability and aesthetic appeal.

Geological facts

Granite makes up a major part of continental crust and is one of the most durable building stones known. Its interlocking crystals provide exceptional strength.

Field identification & locations

Easily identified in the field by its visible interlocking mineral grains of pink or white feldspar, translucent quartz, and dark biotite mica. Found globally in shields and mountain roots.
