An igneous rock in which carbonate minerals make up at least half the volume. Individual occurrences of carbonatite are not numerous (527 have been claimed) and generally are small, but they are widely distributed. Carbonatites are important scientifically because they reveal clues about the composition and thermal history of the Earth's mantle.
