Physical properties
Hardness of 6-7 on the Mohs scale, typically grayish or speckled with pink/white crystals, dull to vitreous luster, phaneritic crystal structure (coarse-grained), specific gravity around 2.65 to 2.75.
Formation & geological history
Formed from the slow cooling and crystallization of magma rich in silica and alkali metals far beneath the Earth's surface.
Uses & applications
Widely used in construction, countertops, monuments, and architectural facings due to its durability.
Geological facts
Granite is the most common igneous rock in the Earth's continental crust and is exceptionally resistant to weathering.
Field identification & locations
Easily identified by its visible interlocking crystals of quartz, feldspar, and mica. Commonly found in continental shield areas and mountain ranges worldwide.
