Formation & geological history
Formed from the slow crystallization of magma deep beneath the Earth's surface over millions of years. Commonly found in continental crusts worldwide.
Uses & applications
Widely used in construction, architectural buildings, monuments, countertops, and paving stones.
Geological facts
Granite is the most common rock of the Earth's continental crust and is frequently used as a benchmark for durability in building materials.
Field identification & locations
Easily identified by its speckled appearance showing interlocking crystals of quartz, feldspar, and mica. Found abundantly in mountain ranges and shields worldwide.
