Formation & geological history
Formed from the slow cooling and crystallization of magma deep beneath the Earth's surface over millions of years.
Uses & applications
Widely used in construction, countertops, monuments, curbing, and flooring due to its durability and aesthetic appeal.
Geological facts
Granite is the most common rock of the Earth's continental crust and is exceptionally resistant to weathering.
Field identification & locations
Easily identified by its visible interlocking crystals of quartz, feldspar, and mica. Commonly found in continental shield areas and mountain ranges worldwide.
