The continental crust is made of granitic rocks, which have even more silicon and aluminum than the basaltic oceanic crust; they also have more oxygen thanks to the atmosphere. Granitic rocks are even less dense than basalt. In terms of minerals, granite has even more feldspar, less amphibole than basalt and almost no pyroxene or olivine, plus it has abundant quartz. In geologist's shorthand, continental crust is felsic.
Accordingly, the crust is divided into two types; the continental crust and the oceanic crust. Oceanic Crust. The oceanic crust is that part of the Earthâs crust that covers the ocean basins. It consists of dark-colored rocks made up of basalt.This rock is made up of silicon, oxygen, and magnesium.The density of the oceanic crust is about 3.0 g/cm3.The continental crust has a lower density. This difference in the average densities allows many natural phenomenon to occur on and below the surface of the Earth. The oceanic crust scarcely floats on the mantle.t consists of dark-colored rocks made up of basalt. This rock is made up of silicon, oxygen, and magnesium.
