Apr 10, 2008 · Basaltic crust is the crust that is formed by seafloor spreading at the mid-ocean ridges. The major component is the igneous rock, basalt, which is more fine-grained and more dense than the granite which makes up continental crust. Thus the continental crust floats higher than the oceanic crust.

The Earth's crust is made up of about 95% igneous and metamorphic rocks, 4% shale, 0.75% sandstone, and 0.25% limestone. The continental crust has an average composition that approximates granodiorite (a medium to siliceous igneous rock), whereas the oceanic crust has an average composition that is basaltic (a low silica igneous rock).
