Physical properties
Hardness of 6 to 7 on the Mohs scale, colors range from pink and white to gray and black depending on mineral content, vitreous to dull luster, phaneritic (coarse-grained) crystal structure, specific gravity around 2.65-2.75.
Formation & geological history
Formed from the slow crystallization of magma below the Earth's surface over millions of years. Common in continental crust and dates across various geological eras from Precambrian to Cenozoic.
Uses & applications
Widely used in construction, monuments, flooring, countertops, and decorative stone due to its durability and aesthetic appeal.
Geological facts
Granite makes up a major part of continental crusts and is one of the most durable natural building stones available, resistant to weathering.
Field identification & locations
Easily identified in the field by its visible interlocking crystals of quartz, feldspar, and mica. Found worldwide in mountainous regions and shield areas.
