Physical properties
Hardness of 6 on the Mohs scale, colors ranging from pink to gray, dull to vitreous luster, phaneritic crystal structure, and a specific gravity of 2.65 to 2.75.
Formation & geological history
Formed from the slow cooling of magma rich in silica and alkali metal oxides deep beneath the Earth's surface over millions of years.
Uses & applications
Widely used in construction for dimensional stone, floor tiles, counter tops, monuments, and curbing due to its high durability.
Geological facts
Granite is the most common intrusive rock in the Earth's continental crust and forms the core of many major mountain ranges.
Field identification & locations
Easily identified by its visible interlocking crystals of quartz, feldspar, and dark mica minerals; found globally in continental shields.
