Why do you think the concentration of iron in magma would not be evenly distributed throughout the mantle?
- samus 3y agoThe magma is not exactly a liquid. Neither is it homogeneous - the roots of the components of continental plates extend down hundreds of kilometers into the mantle. It is also possible to seismologically trace the remains of ancient continental plates which have otherwise all but disappeared from the crust.
