Physical properties
Hardness of 6-7 on the Mohs scale, multicolored (typically pink, white, gray, or black), phaneritic (coarse-grained) luster, interlocking crystal structure, specific gravity around 2.65-2.75.
Formation & geological history
Formed from the slow cooling and crystallization of magma deep beneath the Earth's surface over millions of years.
Uses & applications
Widely used in construction, countertops, monuments, flooring, and architectural facing stone.
Geological facts
Granite is the most common intrusive rock on 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 worldwide in continental shields and mountain roots.
