Physical properties
Mohs hardness of 6-7, composed mainly of quartz, alkali feldspar, and plagioclase. Displays a phaneritic, coarse-grained crystalline texture with pink, white, or gray coloration and a dull to sub-vitreous luster.
Formation & geological history
Formed from the slow, underground cooling of silica-rich magma over millions of years, typically occurring within continental crustal plates.
Uses & applications
Extensively used in commercial construction, dimension stone, architectural facing, countertops, and monumental sculpture.
Geological facts
Granite is the most common plutonic rock on Earth and forms the primary basement rock of many continental landmasses.
Field identification & locations
Easily identified by its interlocking, visible mineral crystals of quartz and feldspar; commonly found in mountainous regions and shield areas.
