Physical properties
Hardness of 6-7 on the Mohs scale, colors range from pink to gray depending on feldspar content, vitreous to dull luster, phaneritic (coarse-grained) crystal structure, specific gravity around 2.65-2.75.
Formation & geological history
Formed from the slow crystallization of magma below the Earth's surface over millions of years, typically associated with continental crust.
Uses & applications
Widely used in construction, architectural buildings, monuments, countertops, and paving stones due to its high durability.
Geological facts
Granite is the most common rock of the Earth's continental crust and forms the core of many major mountain ranges.
Field identification & locations
Easily identified by its visible interlocking crystals of quartz, feldspar, and mica. Found abundantly in shield areas and mountainous regions globally.
