Laboratory studies have shown that the mineral can contain water, which isn't present as liquid, ice or vapor; instead, it is trapped in the ringwoodite's molecular structure as hydroxide ions (bonded oxygen and hydrogen atoms).
As far as I know some creationists suggest that there was an entire layer of pure (by pure I mean: not component of another mineral) liquid (or solid) water that could have burst into the Earth's surface.
The article doesn't support this view. Creationists - and other people who are trying their best to show sceintific evidence to support the flood story - should stop waiting for miracles to happen.
