Physical properties
Hardness of 6 on the Mohs scale; pink, white, gray, and black speckled color; vitreous to dull luster; phaneritic (coarse-grained) crystal structure; 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 feldspar deep beneath the Earth's 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 rock of the Earth's continental crust and forms the core of many major mountain ranges.
Field identification & locations
Easily identified by its distinct interlocking visible mineral grains of quartz, feldspar, and mica. Found globally in shield areas and mountainous regions.
