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.
Oceanic plates are thinner and younger. Together these plates form the lithosphere. Earth's Tectonic Plates, USGS. Continental plates. Igneous, sedimentary and metamorphic rocks form the continents. The basement rocks of the continents are granitic. The minerals in granitic rocks are lighter than the oceanic crust.ntroduction. Crustal plates form the outer layer of the Earth. There are seven major plates and many smaller plates. These tectonic plates are formed from the Earth's crust and uppermost part of the mantle. Types of tectonic plates. There are two types of tectonic plates.
