Physical properties
Hardness of 6 on the Mohs scale, composed mainly of quartz, alkali feldspar, and plagioclase. Features a phaneritic texture with visible interlocking mineral crystals, ranging in color from pink to gray with a dull to vitreous luster.
Formation & geological history
Formed from the slow crystallization of magma beneath the Earth's surface over millions of years, typically associated with continental crust and mountain-building processes.
Uses & applications
Widely used in construction for dimension stone, countertops, flooring, and monuments due to its high durability and resistance to weathering.
Geological facts
Granite is the most common intrusive rock on Earth's crust and forms the core of many major mountain ranges. Its name is derived from the Latin granum, meaning a grain.
Field identification & locations
Easily identified by its characteristic speckled appearance and visible interlocking mineral grains. Found globally in continental shields and intrusive plutons.
