The lower layer of oceanic.

Is granite oceanic crust.

Composition of oceanic crust. On the other hand continental crust remains where it is for billions of years and it is much older than oceanic crust. By contrast the continental crust is made up of light colored granite rocks full of substances like oxygen and silicon. Oceanic crust is made up of several layers with the topmost layer being just 500 meters thick.

Continental crust is typically 40 km 25 miles thick while oceanic crust is much thinner. Continental crust is broadly granitic in composition and with a density of about 2 7 grams per cubic cm is somewhat lighter than oceanic crust which is basaltic i e richer in iron and magnesium than granite in composition and has a density of about 2 9 to 3 grams per cubic cm. Oceanic crust is about 6 km 4 miles thick. It is composed of several layers not including the overlying sediment.

It is thinner denser younger and of different. Oceanic crust is the uppermost layer of the oceanic portion of a tectonic plate it is composed of the upper oceanic crust with pillow lavas and a dike complex and the lower oceanic crust composed of troctolite gabbro and ultramafic cumulates. The topmost layer about 500 metres 1 650 feet thick includes lavas made of basalt that is rock material consisting largely of plagioclase and pyroxene oceanic crust differs from continental crust in several ways. The crust overlies the solidified and uppermost layer of the mantle the crust and the solid mantle layer together constitute oceanic lithosphere.
