Physical properties
Hardness of 6 on the Mohs scale, colors vary from pink to gray depending on feldspar content, dull to glassy luster, phaneritic (coarse-grained) crystal structure, specific gravity around 2.65 to 2.75.
Formation & geological history
Formed from the slow crystallization of magma below Earth's surface over millions of years, commonly associated with continental crust.
Uses & applications
Widely used in construction for countertops, floor tiles, curbing, and monumental architecture due to its durability.
Geological facts
Granite is the most common intrusive rock in the Earth's continental crust and forms the core of many major mountain ranges.
Field identification & locations
Easily identifiable in the field by its interlocking visible crystals of quartz, feldspar, and mica. Found globally in shield areas and mountainous regions.
