The composition of Mars covers the branch of the geology of Mars that describes the make-up of the planet Mars. == Elemental composition == Mars is differentiated, which—for a terrestrial planet—implies that it has a central core made up of high density matter (mainly metallic iron and nickel) surrounded by a less dense, silicate mantle and crust.
