Diamond Suggests Presence of Water Deep Within Earth

sciencehabit writes "A 40 micrometer crystal trapped inside a diamond unearthed by magma in Brazil could help settle a long-standing debate about the amount of water in Earth's mantle. Spectroscopic analysis reveal that the crystal contains hydrogen-oxygen bonds, which suggests it's composed of at least 1.4% water. The place where the diamond was produced--Earth's lower mantle--may not be typical of the entire lower mantle, but if it is then there could be a lot of water down there. This would be important, as changes in the temperature in the mantle could cause it to expel highly pressurized steam, which could lead to volcanic eruptions."

    Hans Keppler, a geologist at the University of Bayreuth in Germany, cautioned against extrapolating the size of the subterranean water find from a single sample of ringwoodite.

    And he also said

    "In some ways it is an ocean in Earth's interior, as visualised by Jules Verne... although not in the form of liquid water," Keppler said in a commentary also published by Nature.

      I find it amazing how much Jules Verne envisioned in 20,000 Leagues Under the Sea. Basically he came up with the idea of a nuclear submarine before the advent of nuclear power. What I also learned even in 1870 when it was published, that very little about Antarctica was known, and the first undisputed landing didn't take place until 1895.

      His writings in Journey To The Center Of The Earth turned out to be much less real, but you still have to admire his imagination.

      Considering how many communities live in coastal areas, I could easily logically deduce that after a great ice age, communities in this area flooded which lead to them being abandoned and left under water today. Some such communities are thought to have existed and some have even been found. A great flood doesn't have to cover the entire earth, just enough of it to affect were civilization exists.

      This is not that foreign of a concept to me. I am surprised that others seem to have a problem with it.

      The predominant theory among creationists is that the water of the flood is mostly most in the oceans -- The elevations of the continental masses where raised, allowing the water to flow to the oceans.

      Long past that point. I can remember seeing something on the internet at least a decade ago talking about not only where the water went to, but where it came from to begin with. The idea that there is water trapped deep in the mantel is not new or surprising. It has been known for along time, this is just more and better evidence.

    No, they already solved that. The most popular YEC explanation is that the water was in a spherical ice shell just at the top of the atmosphere, held in place by divine will. The shell stopped cosmic radiation reaching earth, which is why people could live for many centuries*. Then God said 'screw it' and stopped willing the ice to stay in place, so it fell down and flooded the earth. Where the water went after is more of an issue.

    I thought underground water being stored in molten rock material was already proved during russia's borehole experiment:
    http://en.wikipedia.org/wiki/K...
    "To scientists, one of the more fascinating findings to emerge from this well is that no transition from granite to basalt was found at the depth of about 7 km, where the velocity of seismic waves has a discontinuity. Instead the change in the seismic wave velocity is caused by a metamorphic transition in the granite rock. In addition, the rock at that depth had been thoroughly fractured and was saturated with water, which was surprising. This water, unlike surface water, must have come from deep-crust minerals and had been unable to reach the surface because of a layer of impermeable rock.[8]

    Another unexpected discovery was the large quantity of hydrogen gas; the mud that flowed out of the hole was described as "boiling" with hydrogen"
