Formation & geological history
Formed from the slow crystallization of magma deep beneath the Earth's surface over millions of years.
Uses & applications
Widely used in construction, architectural buildings, monuments, countertops, and decorative tiles.
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 speckled, interlocking crystalline texture visible to the naked eye. Found worldwide in ancient shields and mountain roots.
