Physical properties
Hardness of 6 on the Mohs scale, predominantly pink, white, gray, and black mottled colors with a vitreous to dull luster. Composed primarily of quartz, alkali feldspar, and plagioclase with minor dark minerals like biotite and amphibole. Crystal structure is phaneritic (coarse-grained).
Formation & geological history
Formed from the slow crystallization of magma below Earth's surface over millions of years. It is a major component of continental crust.
Uses & applications
Widely used in construction, architectural buildings, countertops, monuments, and paving stones.
Geological facts
Granite is one of the most abundant rocks in Earth's continental crust and forms the core of many major mountain ranges.
Field identification & locations
Easily identified by its distinct interlocking mineral crystals visible to the naked eye, particularly the pink or white feldspar grains. Found globally in shield areas and mountainous regions.
