This is interesting as it provides a mechanism for local conductivity at least. Yet it does not easily overcome resistance natural to the materials.
My own conjecture works as we go much deeper to the temperature transition zone in which all minerals disassociate. I suspect that that zone comprises liquid carbon if such actually exists and this allows near zero friction allowing instant slippage as well as near zero electrical resistance. This is a pretty radical idea, but it does provide a non controversial solution in terms of our understanding.
Any other protocol will be simply not enough. We have a massive magnetic field to explain. We have rapid crustal movement to explain. Hydrostatic transfer is never rapid and magnetite crystals simply will not provide a uniform bed all around the Earth as there will be too much mixing going on. Yet a liquid carbon phase can act as a separator with heavier elements dropping below the layer and lighter elements remaining above to recombine into the crust
The temperature would be around 6600 C...
