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.
1 The crust is made up of silicate rocks such as granite and basalt. 2  The continental crust is much thicker than the oceanic crust as shown here in the diagram of the earth's crust. 3  Oceanic crust-The crust under the oceans is about 10 km thick and is generally made up of rock rich in iron and magnesium. Continental crust (continental cratons) - Where there are continents the crust is about 30 to 50 km thick. 2  It is made up of igneous, metamorphic, and sedimentary rocks. 3  The continental crust is less dense than the oceanic crust.
