I posted the artisan well quote from the USGS because it simplified the whole PBS "ringwoodite/water retention thing and explains it simply to something you might relate to easier. because you did not seem to either read the material I originally referenced or you did not fully understand it. Which is why I offered the USGS article.
So, do you really need me to really connect the dots? If I do I might sound a little condescending drawing parallels between the two articles.
I'm sorry I could not post the actual link to the articles as this would have made it simpler to follow, but the 30/30 is still in effect.
i have already drawn the dots for you.
You should also have learned all this in high school earth science class in the 8th or 9th grade if you took it within the last 40 years or so, and paid half as much attention as you might have to bible studies. But instead of following the dots, you are huffing and puffing.
So I don't bluff. Too close to lying. You can call it any time you like, just know I can back what I claim.
Steven Jacobsen, the Northwestern University professor who led the study, found water in subterranean ringwoodite, a deep blue mineral chemically similar to peridot, a green mineral often used in jewelry. Until a sample turned up in 2008 in a diamond coughed up from a volcano, ringwoodite had only been found in meteorites. The ringwoodite came from the “transition zone” between the upper and lower mantle, about 400 miles below the Earth’s surface, and about 1.5% of its weight turned out to be water. If a lot of this water-heavy mineral existed underground, scientists reasoned, that might be enough to explain where Earth’s oceans came from.
So Jacobsen and his team went looking for dampness lurking deep underground by monitoring the seismic waves generated by earthquakes. Because the velocity of these waves changes depending on what kind of material they’re passing through—like, for example, if a mineral is wet or dry—measuring that speed can give geologists a map of what’s below the Earth’s surface.
Andy Coghlan, writing for NewScientists:
Quote:Sure enough, they found signs of wet ringwoodite in the transition zone 700 kilometres [400 miles] down, which divides the upper and lower regions of the mantle. At that depth, the pressures and temperatures are just right to squeeze the water out of the ringwoodite. “It’s rock with water along the boundaries between the grains, almost as if they’re sweating,” says Jacobsen.If all the ringwoodite in the transition zone is as damp as the samples that Jacobsen and his team detected, that layer would hold three times as much water as all of the Earth’s oceans combined, reducing their share from 96.5% of all known water to a relatively paltry 24.8%. In other words, the ringwoodite discovery could quadruple the amount of water found on Earth. A blue planet, indeed.
Squeeze the water out of the ringwoodeite under great pressure.. kinda like an artesian well
