Burning rock for fuel

Could common granite react exothermically with 100% oxygen?

If you subject granite to a high pressure oxidizer can the reaction be exothermal? I realize that the components of granite are already oxidized but what if you can form a multi-compound complex reaction which is exothermal i.e. involving fe(II)=>fe(III) and less nobel metals pushed to more oxidation than more noble metals. If you look at this video, there seems to be more energy than than the reaction with iron wooll, is the rock itself reacting exothermically: https://www.youtube.com/watch?v=EA- VCaBUsCA Likewise, termite may create a lot of heat and could be composed of oxides of different metalls. The components SiO2, Al2O3, K2O, Na2O, CaO, FeO, Fe2O3, MgO, TiO2, P2O5, MnO (see wikipedia for percentages) gives plenty of room for reactions. Oxygen is cheap, and can be separerad from the atmosphere using little extra energy. So, can you use granite as a viable cheap energy source?

       [marked-for-deletion] apparently identical duplicate.
I think jan was trying to fix the in-body link.

       The other one ("Burning rock for fuel2") has annotations, but could be renamed.
