Physical properties
Hardness of 6-7 on the Mohs scale, predominantly light-colored with pink, white, and gray hues, granular phaneritic crystal structure, dull to subvitreous luster, specific gravity of 2.65-2.75.
Formation & geological history
Formed from the slow cooling and crystallization of magma beneath the Earth's surface, typically over millions of years.
Uses & applications
Widely used in construction, architectural buildings, monuments, countertops, and decorative stone flooring.
Geological facts
Granite is the most common intrusive 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 crystals of quartz, feldspar, and mica. Found globally in shield areas and continental mountain chains.
