The water-rich nature of this inclusion, indicated by infrared absorption, along with the preservation of the ringwoodite, is direct evidence that, at least locally, the transition zone is hydrous, to about 1 weight per cent.

a reply to: Phage Water that can't flow, really? Think on that before you reply, for your sake. With all due respect of course.
I thought there were both crystallized water below and liquid water below in caverns,rivers
The only crystallized water I know of is ice. This is not ice. This is hydrated chemicals and no, if liquid water touches it it does not free liquid water.
once the liquid water touches the crystallized water can it change the crystal to liquid water?
Mineral hydration is an inorganic chemical reaction where water is added to the crystal structure of a mineral, usually creating a new mineral, usually called a hydrate.
In geological terms, the process of mineral hydration is known as retrograde alteration and is a process occurring in retrograde metamorphism. It commonly accompanies metasomatism and is often a feature of wall rock alteration around ore bodies. Hydration of minerals occurs generally in concert with hydrothermal circulation which may be driven by tectonic or igneous activity.
Mineral hydration is also a process in the regolith that results in conversion of silicate minerals into clay minerals.
There are two main ways in which minerals hydrate. One is conversion of an oxide to a double hydroxide, as with the hydration of calcium oxide—CaO—to calcium hydroxide—Ca(OH)2, the other is with the incorporation of water molecules directly into the crystalline structure of a new mineral, as in the hydration of feldspars to clay minerals, garnet to chlorite, or kyanite to muscovite.
Some mineral structures, for example, montmorillonite, are capable of including a variable amount of water without significant change to the mineral structure.
Hydration is the mechanism by which hydraulic binders such as Portland cement develop strength. A hydraulic binder is a material that can set and harden submerged in water by forming insoluble products in a hydration reaction. The term hydraulicity or hydraulic activity is indicative of the chemical affinity of the hydration reaction.
Finally, here’s a fun thought that should remind us that Earth’s perfect composition and climate is, if you look very closely, rather miraculous. One of the researchers, talking to New Scientist, said that if the water wasn’t stored underground, “it would be on the surface of the Earth, and mountaintops would be the only land poking out.” Maybe if the formation of Earth had be a little different, or if we were marginally closer to the Sun, or if a random asteroid didn’t land here billions of years ago… you probably wouldn’t be sitting here surfing the web.
