Physical properties
Hardness of 6 on the Mohs scale with a specific gravity of 2.65 to 2.75. Displays a pinkish-orange and black speckled coloration due to a coarse-grained phaneritic texture with vitreous luster.
Formation & geological history
Formed through the slow, subterranean cooling and crystallization of silica-rich magma over millions of years.
Uses & applications
Widely utilized in architectural construction, countertops, monuments, and decorative stone work.
Geological facts
Granite forms the vast majority of Earth's continental crust and is frequently found in major mountain ranges worldwide.
Field identification & locations
Easily identified in the field by its interlocking visible crystals of quartz, feldspar, and dark micas or amphiboles. Common in continental shields and intrusive plutons.
