Physical properties
Hardness of 6 on the Mohs scale, colors ranging from pink to gray, dull to subvitreous luster, and a phaneritic crystal structure. It exhibits interlocking quartz, alkali feldspar, and plagioclase crystals.
Formation & geological history
Formed from the slow cooling of silica-rich magma beneath the Earth's surface over millions of years. It is a major component of continental crusts.
Uses & applications
Widely used in construction for dimensional stone, countertops, flooring, and monumental architecture.
Geological facts
Granite is the most common plutonic rock on Earth and forms the core of many major mountain ranges. Its high quartz and feldspar content makes it exceptionally durable against weathering.
Field identification & locations
Easily identified by its visible, interlocking mineral grains of quartz, feldspar, and mica. Found globally in shield areas and mountainous regions.
