Granite

Mohs hardness 6-7, salt-and-pepper (white, gray, black) color, vitreous to dull luster, phaneritic (coarse-grained) crystalline texture, irregular fracture, specific gravity around 2.63-2.75

Forms deep underground through the slow cooling and crystallization of silica-rich felsic magma over millions of years within continental crust intrusions (batholiths and stocks).

Widely used in construction as building stone, dimension stone, crushed stone for road base, countertops, monuments, and curbing.

Granite makes up a large portion of the Earth's continental crust. It contains high amounts of quartz and feldspar, along with darker minerals like biotite mica or hornblende.

Identified by its visible, interlocked mineral grains of quartz (glassy/clear), feldspar (white/pink), and dark ferromagnesian minerals. Commonly found in mountainous regions, shield areas, and gravel/soil derived from eroded granitic bedrock.
