    No. Oceanic Crust is way denser that continental crust. Bassically the Oceanic crust is made with volcanic rocks and intrussions from the Mantle (which is more dense than the crust) and it has densities of about 2.9 grams/cubic centimeter.

    Continental crust is about 2.7 gr/cc, becase is made from less dense rocks as granites or limestones.

    I hope it helps.
