Physical properties
Hardness: 6-7 on Mohs scale. Colors typically include white, pink, grey, or black depending on mineral content. Luster ranges from dull to vitreous. Granular, phaneritic crystal structure. Specific gravity: 2.65-2.75.
Formation & geological history
Formed from the slow crystallization of magma below the Earth's surface over millions of years. Commonly found in continental crusts and mountain ranges.
Uses & applications
Widely used in construction, buildings, monuments, countertops, paving, and decorative aggregate.
Geological facts
Granite is one of the most abundant rocks in Earth's continental crust and is also found on other terrestrial planets like Mars.
Field identification & locations
Easily identified by its visibly interlocking mineral crystals of quartz, feldspar, and micas. Found globally in shield areas and mountainous regions.
