Physical properties
Hardness of 6 on the Mohs scale, colors vary from pink to gray depending on mineral content, vitreous to dull luster, phaneritic crystal structure with visible grains of quartz, feldspar, and mica, specific gravity around 2.65 to 2.75
Formation & geological history
Formed from the slow cooling and solidification of molten magma beneath the Earth's surface over millions of years
Uses & applications
Commonly used in construction, countertops, monuments, and architectural facings due to its durability
Geological facts
Granite is the most common igneous rock in the Earth's continental crust and is a major component of mountain ranges
Field identification & locations
Easily identified by its interlocking, visible mineral crystals, particularly the presence of clear to white quartz and pink or white feldspar
