Physical properties
Hardness of 6 on the Mohs scale, colors typically range from pink to gray depending on feldspar content, phaneritic texture with visible interlocking mineral crystals, specific gravity around 2.65 to 2.75.
Formation & geological history
Formed from the slow cooling and solidification of magma rich in silica and alkali metal oxides deep beneath the Earth's continental crust over millions of years.
Uses & applications
Widely used in construction, countertops, architectural facing stones, monuments, and paving materials.
Geological facts
Granite is the most common rock of the Earth's continental crust and is exceptionally durable against weathering.
Field identification & locations
Easily identified by its speckled, coarse-grained appearance containing quartz, feldspar, and mica. Found globally in major mountain ranges and shield areas.
