Word Origin & History
plutonic
"pertaining to or involving intense heat deep in the earth's crust," 1796, from Pluto (q.v.) as god of the underworld; especially in ref. to early 19c. geological theory (championed by Hutton) that attributed most of the earth's features to action of internal heat, and which
triumphed over its rival, neptunism, which attributed them to water.
