Physical properties
Hardness of 6 on the Mohs scale, colors range from pink to gray depending on feldspar content, dull to 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 ranging from Precambrian to Cenozoic geological ages.
Uses & applications
Widely used in construction, architectural buildings, countertops, monuments, paving stones, and landscaping.
Geological facts
Granite makes up a major part of the Earth's continental crust and is exceptionally durable against weathering.
Field identification & locations
Identified by its visible interlocking crystals of quartz, feldspar, and mica. Found globally in continental shields and mountain ranges.
