Formation & geological history
Formed from the slow cooling and crystallization of magma beneath the Earth's surface over millions of years.
Uses & applications
Widely used in construction, architectural buildings, kitchen countertops, monuments, and decorative paving stones.
Geological facts
Granite is the most common igneous rock in the Earth's continental crust and forms the core of many major mountain ranges.
Field identification & locations
Easily identified by its interlocking crystals of quartz, feldspar, and biotite mica. Found abundantly in continental shields globally.
