Physical properties
Hardness of 6 on the Mohs scale, predominantly light-colored (white, pink, gray) with darker mineral specks, granular texture, dull to glassy luster, density around 2.65-2.75 g/cm³.
Formation & geological history
Formed from the slow cooling and solidification of magma below the Earth's surface, typically composed mostly of quartz, alkali feldspar, and plagioclase.
Uses & applications
Commonly used in construction, architectural buildings, countertops, monuments, and paving stones.
Geological facts
Granite is the most common igneous rock in the Earth's continental crust and is exceptionally durable against weathering.
Field identification & locations
Easily identified by its visible interlocking mineral grains (quartz and feldspar); found worldwide in continental shields and mountain roots.
