Formation & geological history
Formed from the slow crystallization of magma beneath the Earth's surface over millions of years, typically associated with continental crust.
Uses & applications
Widely used in construction, architectural buildings, countertops, monuments, and paving stones.
Geological facts
Granite is the most common rock of the Earth's continental crust and is frequently found in major mountain ranges. It provides exceptional durability against weathering.
Field identification & locations
Easily identified by its interlocking visible grains of quartz, feldspar, and micas. Found globally in shield areas and batholiths.
