Sun Mar 16, 2014, 09:30 PMnadinbrzezinski (131,306 posts) THERE'S AN OCEAN DEEP INSIDE THE EARTHIn what sounds like a chapter from Journey to the Center of the Earth, the chemical makeup of a tiny, extremely rare gemstone has made researchers think there's a massive water reservoir hundreds of miles under the earth. The gemstone in question is called ringwoodite, which is created when olivine, a material that is extremely common in the mantle, is highly pressurized; when it’s exposed to less pressurized environments, it reverts into olivine. It has previously been seen in meteorites and created in a laboratory, but until now it had never been found in a sample of the earth’s mantle. Diamond expert Graham Pearson of the University of Alberta came across a seemingly worthless, three-millimeter piece of brown diamond that had been found in Mato Grosso, Brazil, while he was researching another type of mineral. Within that diamond, he and his team found ringwoodite—and they found that roughly 1.5 percent of the ringwoodite’s weight was made up of trapped water. The findings are published in Nature.http://www.vice.com/en_au/read/theres-an-ocean-deep-inside-the-earth-mb-test See, nothing to worry about if we ruin surface water...

The crazy bald dwarf demonstrates how to start a kerfunkle even with a stupid kpete-ish copy-and-paste:http://www.democraticunderground.com/10024675540Surely DUmmy sad-cafe knows the answer to that question.

I assume there are many aquifiers of varying depths all under the surface of the planet...even as deep as the transition zone between the mantle and the crust. Superheated and highly pressurized liquid water is well known to exist at extreme depths, much of it carried down from the crust when it subsumes into the mantle. I wouldn't be surprised if there is enough water trapped within minerals, trapped in deep pockets within the crust, etc. to equal the amount of water found on the surface.
Tony Carmello Gatts IV · Lab Technician at Sexing TechnologiesThe graphic is misleading people, it's not a literal ocean beneath an ocean. All that water is bound up in crystal lattices.Reply · 21 · Like · Follow Post · March 15 at 2:30pm William Tatum · Top Commenter · Corvallis, Oregon This was my thought exactly, this isn't water in its liquid form, it is just water molecules trapped inside other solids. It isn't like we can drill down and start siphoning it out.
