Physical properties
Hardness of 6-7 on the Mohs scale, colors ranging from pink to gray depending on mineral makeup, dull to glassy luster, granular and phaneritic crystal structure, specific gravity around 2.65-2.75.
Formation & geological history
Formed from the slow cooling and crystallization of magma rich in silica and alkali feldspar deep beneath the Earth's surface over millions of years.
Uses & applications
Commonly used in construction, countertops, monuments, paving stones, and architectural facings.
Geological facts
Granite is one of the most abundant rocks in the continental crust of the Earth and is known for its exceptional durability.
Field identification & locations
Easily identified by its visibly speckled or crystalline texture consisting of interlocking mineral grains like quartz, feldspar, and mica. Found worldwide in continental shields and mountain ranges.
