Conduction mechanisms in the mantle

ionic conduction due to movement of mobile charged ions

1) partial melt
2) H+ diffusion
3) hydrous mineral phase
(e.g. phlogopite)


electronic conduction due to movement of electrons
4) sulphides
4) carbon on grain boundary films or as graphite

<-- heroic hypothesis!

<-- possible

<-- no

<-- preferred hypothesis

<-- no
