Solid rock or is magma metallic.
Subterranean currents might be the heating cause.
Even so with some metallic content there might be non metallic compounds carries along.
Also all matter composed of electrically charged atoms and both metal and non metals
can carry static charges, like Ben Franklin once showed us, who's forces might move
the Earth and planets. So moving great flows of magma might be wave force related and
not cool magma mixing with hot magma. The cool magma must have been heated by
extreme static forces under the Earth. Thus we might be able to detect the flow or waves.
