Isn't the methane emitted from mud volcanoes originally biological in origin, even if it's geological now?

Isn't the methane emitted from mud volcanoes originally biological in origin, even if it's geological now? Dunno. I always assumed it was from oxidation of iron minerals with H2 reduction of carbonate rocks. (http://en.wikipedia.org/wiki/Serpentinite) [olivine + wa-wa + carbon dioxide --> serpentine + magnetite + methane] (Fe,Mg)2SiO4 + nH2O + CO2 --> Mg3SiO5(OH4) + Fe3O4 + CH4 -Mike -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/
