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 of magma rich in silica and alkali metals deep beneath the Earth's surface, typically during various geological periods spanning millions of years.
Uses & applications
Widely used in construction, countertops, monuments, and architectural facings due to its durability and resistance to weathering.
Geological facts
Granite is the most common igneous rock in the Earth's continental crust and forms the core of many major mountain ranges.
Field identification & locations
Identifiable by its visible interlocking crystals of quartz, feldspar, and mica. Commonly found in shield areas and mountainous regions worldwide.
