Physical properties
Hardness of 6 on the Mohs scale, predominantly pink to grey or white color with dark mineral flecks, vitrified or dull to sub-vitreous luster, phaneritic (coarse-grained) crystal structure, specific gravity around 2.65 to 2.75.
Formation & geological history
Formed from the slow cooling and crystallization of magma beneath the Earth's surface, often dating back billions of years across continental shields.
Uses & applications
Widely used in construction, architectural building facades, countertops, monuments, and as crushed stone for paving.
Geological facts
Granite is the most common intrusive rock of Earth's continental crust and is exceptionally durable against weathering.
Field identification & locations
Easily identified by its speckled pink, white, and black appearance composed primarily of quartz, feldspar, and biotite mica. Found globally in mountainous regions and continental cratons.
