Physical properties

Hardness of 6 on the Mohs scale, predominantly pink, white, or gray with speckled mineral grains, dull to vitreous luster, phaneritic crystal structure, and specific gravity around 2.65-2.75.

Formation & geological history

Formed through the slow cooling and crystallization of magma beneath the Earth's crust, occurring over millions of years in continental tectonic settings.

Uses & applications

Extensively used in commercial construction, kitchen countertops, monuments, and architectural facings due to its high durability.

Geological facts

Granite is the most common intrusive rock on Earth's continents and forms the foundational core of many major mountain ranges.

Field identification & locations

Easily identified in the field by its interlocking visible grains of quartz, feldspar, and mica; found worldwide in continental shields and intrusive plutons.
