OK, not that we need it, but I will ask: How does this, in principle at least, oppose and exclude support for the Biblical account, if the water-rich mantle plumes can migrate upwards and break through the boundary to the upper mantle, so that water contained in the mantle plumes is released?
Please re-read my post.
Overwrought interpretations of half-understood scientific papers providing weak support for or at least not outright opposing established Biblical doctrines are of little to no use...
I am saying that an article which seems to slightly support the Bible, or which - at best - doesn't contradict it, should be given only minimal attention.
It's not Earth-shaking. And it encourages a certain mode of thinking that can lead down dark paths.
Understand now?
