This article talks about lithespheric foundering, which I don't understand, but it mentions in there how oceanic and continental crust is different, namely that the continental crust is less dense.
Continental crust I understand, is granitic. The thing with granitic minerals is that you can't just take molten rock and let it cool and get granite. Instead you'd get basalt, which is the oceanic crust. So the article suggests that lithospheric foundering made the continents, but doesn't explain how this process could form the unique features of granite, where different compounds form distinct crystals within the rock like how granite is. It doesn't address that feature of granite at all, it more says that the lithospheric foundering, which it likens to peeling, separates denser rock from the less dense continental rock.
One of the big mysteries to me personally is where all the rest of the continental crust went, because one idea is that (and I think is Dr. Walt Brown's idea too) the Earth used to be fairly uniformly covered in granitic continental crust, but that the Flood is the reason only about 30% is left. The rest either all blew into Outer Space, or was melted down and became basaltic oceanic crust.
So any information or insight on where continental crust either came from or went, is on topic here.
