Magma resultant from group 1 and group 2 elements?

Question

I was recently speaking with a geology professor over lunch at a university who has a theory that I've never heard before. His postulation was quite compelling and I was hoping to do a little digging to see if anyone else has heard of such a theory with any supporting evidence. Apparently this fellow is onto quite a discovery, but is not yet ready to release his findings. Quite a bit of the discussion was simply over my head since I have never really studied geology in depth.He sets forth that magma is not actually created from heat / pressure buildup, etc., but rather that it is generated from a catalytic reaction from massive interactions of water with large group 1 and group 2 metal pockets or clusters within the earth's crust.He further explained how the water enters into these pockets via various fissures both from our oceans and other bodies of water (noting some study from last year where researchers found incredible volumes of water 700 kilometers underground). One side note was regarding the contents of magmatic rocks being surprisingly high in alkali metals, etc.As I noted, it was quite compelling, but I was out of my depth and I was curious as to whether others have heard such theories or seen such data before as I would quite like to understand this topic a bit better.

Answer 1

It would take abnormally high amounts of alkali metals to create all of the magma we see. Also water reacts with these metals in an explosive way. Lastly, if this were the case, after the volcano erupts, the 1st rain would cause the solidified rock to melt again. Since this doesn't happen, this theory is just that -- a theory.
