Physical properties
Hardness of 6 on the Mohs scale, pink to grey color depending on feldspar content, dull to sub-vitreous luster, phaneritic (coarse-grained) 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, typically continental crust, over millions of years.
Uses & applications
Widely used in construction, monuments, flooring, countertops, and decorative stone due to its durability and aesthetic appeal.
Geological facts
Granite is the most common intrusive igneous rock in the Earth's continental crust and forms the core of many mountain ranges.
Field identification & locations
Easily identified by its visibly speckled, interlocking mineral grains of quartz, feldspar, and mica. Found worldwide in shield areas and mountainous regions.
