Title: Real Earth geology: "Mineral hints at bright blue rocks deep in the Earth"

Mineral hints at bright blue rocks deep in the Earth
BBC article: http://www.bbc.com/news/science-environment-26553115 (http://www.bbc.com/news/science-environment-26553115)
Discussed at Hacker News: https://news.ycombinator.com/item?id=7389728 (https://news.ycombinator.com/item?id=7389728)

Apparently 1% water under pressure is the key to adamantite's features.
I think I'll make a mod that changes adamantite's name to ringwoodite.

That's pretty awesome.

Just hope they don't get any crazy ideas about digging down there and mining it ;P

I read about that on ScienceDaily.com, but it didn't saying anything about ringwoodite being bright blue.

I meant in the article itself: http://www.sciencedaily.com/releases/2014/03/140312150229.htm

Also, the mineral can come in lots of colors other than blue and is a polymorph of olivine: http://en.wikipedia.org/wiki/Ringwoodite

Found in diamonds? So the material is related to diamonds? An... adamantine material? Hehe.

More on ringwoodite: it's full of water, like three times as much water as is in our oceans.

This is fascinating, thanks for the links.  A link on those pages to the earth-always-had-water hypothesis (didn't come from comets) was broken though, what's the gist of that?

Wikipedia presents an overview of the various theories.  Basically, the elements that make up water were everywhere as the solar system formed, so naturally the earth had them too, and was located in a zone that let them present as liquid water.

Also some discussion on Hacker News, with calculations of how much water there would be in a 3d sphere layer of raw adamantineringwoodite.

This makes me think if similar reservoirs could exist on other planets...

...They do? We know Ceres, Ganymede, Mars, the Moon, Europa and Callisto to all have craptons of water AFAIK. Because as it turns out, the fact that oxygen and hydrogen are both common as hell in the universe and that both H2 and O2 are unstable compared to H2O means that water's friggin everywhere.

We should mine it all and build a subterranean circus underneath where we found it.

According to modern mythology, we have already dug too deep (http://en.wikipedia.org/wiki/Well_to_Hell_hoax) once. Might as well do it again.

Whatever we do, don't accidentally drop any copper picks down the hole. We'd be proper borked then.

I've already dug down here, we eat the adamantine and brew it into an alcoholic tea. These are the homelands of the trolls.

Where there is water there is life.

if dwarves with late medival technology can curbstomp demons, I'm pretty sure we can do the same.
