Hi, Most of the Earth is composed of Silicon dioxide combined with other metal oxides, frequently in the form of silicates.
Consider the nuclear reaction:- Si28 + 2 O16 -> 4 H + Fe56 +0.478 MeV If this occasionally became possible near the core, then it would slowly convert abundant SiO2 into Iron, causing the core to grow at the expense of the rest, while releasing both heat and Hydrogen, see http://en.wikipedia.org/wiki/Abiogenic_petroleum_origin .
