Physical properties
Hardness of 6 on the Mohs scale, typically speckled pink, white, grey, or black with a dull to subvitreous luster and a phaneritic (coarse-grained) crystal structure.
Formation & geological history
Formed from the slow cooling and crystallization of magma rich in silica and alkali metal oxides beneath the Earth's surface, typically over millions of years.
Uses & applications
Widely used in construction, architectural building facades, countertops, monuments, and paving stones.
Geological facts
Granite is the most common rock in the Earth's continental crust and is exceptionally durable against weathering.
Field identification & locations
Easily identified by its distinct salt-and-pepper or pink-speckled appearance composed of visible interlocking crystals of quartz, feldspar, and micas.
