Granite: Granite is a common and widely occurring type of intrusive, felsic, igneous rock. Granites are usually medium to coarse grained, occasionally with some individual crystals larger than the groundmass forming a rock known as porphyry. Granites can be pink to dark grey or even black, depending on their chemistry and mineralogy.
