Physical properties
Hardness of 6 on the Mohs scale, colors ranging from pink to gray depending on mineral content, vitreous to dull luster, coarse-grained phaneritic crystal structure, no distinct cleavage planes, specific gravity around 2.65 to 2.75.
Formation & geological history
Formed from the slow cooling and solidification of molten magma beneath the Earth's surface over millions of years.
Uses & applications
Widely used in construction, countertops, monuments, architectural facing, and curbing due to its high durability.
Geological facts
Granite is the most common rock of the Earth's continental crust and is frequently found in major mountain ranges.
Field identification & locations
Easily identifiable in the field by its interlocking visible crystals of quartz, feldspar, and mica. Found abundantly globally in shield areas and mountain cores.
