Formation & geological history
Formed from the slow cooling and solidification of magma deep beneath the Earth's surface, typically ranging from Precambrian to Cenozoic eras.
Uses & applications
Widely used in construction, monument building, countertops, flooring, and architectural facades.
Geological facts
Granite is the most common rock of the Earth's continental crust and is frequently found in continental shield areas.
Field identification & locations
Easily identified by its visible interlocking crystals of quartz, feldspar, and mica. Common globally in mountainous regions and shield areas.
