Physical properties
Hardness of 6-7 on the Mohs scale, colors range from pink to gray depending on mineral content, phaneritic (coarse-grained) texture, vitreous to dull luster, specific gravity of 2.65-2.75.
Formation & geological history
Formed from the slow cooling and crystallization of magma rich in silica and alkali aluminum silicates deep beneath the Earth's surface over millions of years.
Uses & applications
Widely used in construction, monuments, floor tiles, countertops, and architectural facing due to its durability and aesthetic appeal.
Geological facts
Granite is the most common igneous rock found in Earth's continental crust and forms the core of many major mountain ranges.
Field identification & locations
Easily identified by its visible interlocking crystals of quartz, feldspar, and mica. Found abundantly globally, particularly in continental shields and intrusive plutons.
