Physical properties
Hardness of 6 on the Mohs scale, colors vary from pink to gray depending on feldspar content, vitreous to dull luster, granular phaneritic crystal structure, specific gravity around 2.65 to 2.75.
Formation & geological history
Formed from the slow cooling and solidification of magma deep beneath the Earth's surface over millions of years.
Uses & applications
Widely used in construction, architectural buildings, countertops, monuments, and paving stones.
Geological facts
Granite is the most common rock of the Earth's continental crust and is exceptionally durable against weathering.
Field identification & locations
Easily identified by its visible interlocking crystals of quartz, feldspar, and mica. Found globally in mountainous regions and continental shields.
