What Is Granite And How Is It Formed? - Geology In
Granite is an intrusive igneous rock, which means it was formed in place during the cooling of molten rock.Generally, the slower the molten rock cooled, the larger it’s mineral crystals with K-Feldspar megacrysts forming in special circumstances greater than 5cm.Granite Rock | Properties, Formation, Composition, Uses,,Granite is the most common intrusive rock in Earth’s continental crust, It is familiar as a mottled pink, white, gray, and black ornamental stone.It is coarse- to medium-grained. Its three main minerals are feldspar, quartz, and mica, which occur as silvery muscovite or dark biotite or both.The Rock GRANITE (Igneous Intrusive Rock),Granite is possibly the most common igneous rock type known to the general public.
