Physical properties

Formation & geological history
Formed by the slow crystallization of silica-rich magma beneath the Earth's surface in continental crustal environments. Often associated with Precambrian cratons and mountain-building events.
Uses & applications
Extensively used in construction for countertops, floor tiles, paving stones, curbing, and monuments. Also used as decorative landscaping stone and crushed aggregate.
Geological facts
Granite is the most common rock found in the Earth's continental crust. The pink color is specifically attributed to a high concentration of orthoclase feldspar.
Field identification & locations
Identify by its interlocking crystalline texture (visible crystals) and high hardness. Found globally in mountainous regions and shield areas like the Canadian Shield or the Llano Uplift in Texas.
