Physical properties
Hardness of 6 on the Mohs scale, colors typically range from pink, white, grey to beige with dark mineral speckles, dull to vitreous luster, phaneritic (coarse-grained) crystal structure, specific gravity around 2.65 to 2.75.
Formation & geological history
Formed from the slow cooling of magma rich in silica and alkali metals far beneath the Earth's surface over millions of years.
Uses & applications
Widely used in construction, monuments, countertops, flooring, and curbing due to its high durability and resistance to weathering.
Geological facts
Granite is the most common igneous rock in the Earth's continental crust and forms the core of many major mountain ranges.
Field identification & locations
Easily identified by its visible, interlocking mineral grains (quartz, feldspar, and micas). Commonly found in continental shield areas and mountainous regions worldwide.
