http://www.bbc.co.uk/news/science-environment-26553115 Minerals preserved in diamond have revealed hints of the bright blue rocks that exist deep within the Earth. They also provide the first direct evidence that there may be as much water trapped in those rocks as there is in all the oceans. The diamond, from central-west Brazil, contains minerals that formed as deep as 600km down and that have significant amounts of water trapped within them. Researchers have published their findings in the journal Nature. The study suggests water may be stored deep in the interiors of many rocky planets. This makes sense, actually. That had always puzzled me about subduction zones underneath the sea: where does all the water go? |

I wonder if they've found a way to extract water from opals. Because opals, chemically, contain water. Obviously if the water were removed from the structure they wouldn't be opals anymore.

It'd be interesting to find out. Would there be any reason for bothering, though ?

Depends on the amount of water that could be derived from them. Australia's not exactly western BC when it comes to rainfall, but with (apparently) 97% of the world's opals coming from there, that might make a difference. Or it might not. Who knows? |

This makes me want to imagine a world where water is scarce, but opals are plentiful - where it might be feasible . (Though, that raises the question of how all those opals formed!) |
