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

I always assumed it was from oxidation of iron minerals with H2 reduction of carbonate rocks.

Well researched. A theory is that water, iron oxide, C02 from the atmosphere, and volcanic heat could cause reactions resulting in methane production. However... we have yet to see evidence of ongoing volcanism (not that it's conclusive, we just don't have the evidence there). Given results from various orbiters and Mars Phoenix Lander, there is plenty of evidence to support the possibility of bacterial life on Mars. We've found plenty of water-ice, the other chemicals (perchlorates, etc) we've found do not eliminate life (as we know it) as a possibility. Everywhere we find water on the Earth, we find something living in it. In any case... it's pretty neat! [the other] -Mike --- Dunno.

The smarter you are, then, the more likely it is you are surrounded by idiots.
