Physical properties
Hardness of 6 on the Mohs scale, colors ranging from pink to gray depending on feldspar content, dull to glassy luster, phaneritic (coarse-grained) crystal structure, specific gravity around 2.65 to 2.75.
Formation & geological history
Formed from the slow cooling and solidification of magma below the Earth's surface, typically composed mostly of quartz, alkali feldspar, and plagioclase.
Uses & applications
Widely used in construction, monuments, countertops, flooring, and exterior cladding 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 identified by its visibly speckled, interlocking mineral crystals of quartz, feldspar, and mica. Found globally in shield areas and mountain cores.
