A term that is sometimes used for oceanic crust rocks is sima, which is short for magnesium silicate, a common component of these rocks. Another term for these undersea igneous rocks is mafic, which comes from the fact that they are high in magnesium and iron.

Oceanic Crust is basically made of basaltic rocks. The floor of the oceans is made up of rocks containing mainly silica and magnesium. This is why it is referred to as Sima.

Oceanic crust, cross section of Earth’s outer layers and pyroxene). Oceanic crust differs from continental crust in several ways: it is thinner, denser, younger, and of different chemical composition. Like continental crust, however, oceanic crust is destroyed in subduction zones.

Oceanic crust, cross section of Earth’s outer layers [the outermost layer of Earth’s lithosphere that is found under the oceans and formed at spreading centres on oceanic ridges, which occur at divergent plate boundaries. It is composed of several layers, not including the overlying sediment. The topmost layer, about 500 metres (1,650 feet) thick, includes lavas made of basalt (that is, rock material consisting largely of plagioclase [feldspar] and pyroxene). Oceanic crust differs from continental crust in several ways: it is thinner, denser, younger, and of different chemical composition.
