Physical properties

Hardness of 6 on the Mohs scale, colors vary from pink to gray depending on feldspar content, dull to vitreous 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 over millions of years.

Uses & applications

Widely used in construction, countertops, monuments, 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 identified by its visible interlocking grains of quartz, feldspar, and mica. Found globally in shields and tectonic plate boundaries.
