Physical properties
Hardness of 6-7 on the Mohs scale, colors ranging from pink to gray depending on its feldspar content, vitreous to dull luster, granular and phaneritic crystal structure, poor to indistinct cleavage, specific gravity of 2.65-2.75
Formation & geological history
Formed from the slow cooling of magma rich in silica and alkali metal oxides beneath the Earth's surface over millions of years
Uses & applications
Widely used in construction, monuments, countertops, paving stones, and architectural cladding
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 distinct interlocking mineral grains of quartz, feldspar, and mica; found globally in mountainous regions and shield areas
