Physical properties
Hardness of 6 on the Mohs scale, colors typically white, pink, gray, or black due to mineral content, glassy to dull luster, interlocking crystalline structure, specific gravity around 2.65-2.75.
Formation & geological history
Formed from the slow crystallization of magma below Earth's surface over millions of years, common in continental crust.
Uses & applications
Widely used in construction, building facades, countertops, monuments, and curbing.
Geological facts
Granite makes up a major part of the continental crust on Earth and is one of the most durable natural building stones.
Field identification & locations
Easily identified by its speckled appearance showing visible interlocking crystals of quartz, feldspar, and biotite mica. Found globally in mountainous regions and shield areas.
