from L. granum.] A crystalline rock composed of mica, quartz, and feldspar. In granite each of these minerals is in fragments large enough to be recognized by the naked eye. It occurs in large masses, which have been intruded in many other kinds of rock, and also in smaller masses and veins. It belongs to the class of eruptive rocks, or those which have been pushed up from beneath to the surface by the action of heat. It is met with in great abundance both in Europe and America, and is much used in public buildings, in making docks, and in paving streets.
