Physical properties
Hardness of 6-7 on Mohs scale, visible interlocking crystals of quartz, feldspar, and mica, phaneritic texture, specific gravity of 2.65-2.75.
Formation & geological history
Formed from the slow cooling and crystallization of magma beneath the Earth's surface over millions of years.
Uses & applications
Widely used in construction, countertops, monuments, and architectural facings due to its durability.
Geological facts
Granite is the most common rock of the Earth's continental crust and is completely absent on oceanic crust.
