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.
The crust is divided  into two types: oceanic crust and continental crust. Oceanic crust,  found under the ocean floor, is made of dense rocks such as  basalt. It â¦is about 7 kilometers (4 miles) thick.  Continental crust, found under land masses, is made of less dense  rocks such as granite.
