This may have already been discussed here, but what are the prevailing theories that attempt to explain why there is so much helium trapped in natural gas formations? It makes no sense to me. What causes He to be trapped in these formations in first place and not somewhere else?
I seem to recall there may exist a controversial theory (or two) involving transmutation. BTW, how much residual radioactivity tends to exist in the surrounding formations? Regards, Steven Vincent Johnson www.OrionWorks.com www.zazzle.com/orionworks
