Plutonic rocks are such igneous rocks as have been formed under conditions of depth and pressure, and have cooled slowly, so as to have acquired in general a distinctly crystalline structure ; the term Plutonic is opposed to volcanic, the former designating rocks formed at some depth beneath the surface, the latter rocks of igneous origin but of superficial formation. As used by Lyell, the word is nearly the equivalent of metamorphic. [Century Dictionary, 1895]
