Earth's Most Abundant Mineral Finally Sampled

Scientists Have Finally Sampled the Most Abundant Material on Earth | Motherboard:

Huh, how can it be most abundant and yet not sampled yet. Well, the answer is DEEP man, REALLY DEEP ... as in like 660mi deep.

The article is not all that interesting, "bridgemanite" is the new stuff.  The ringwoodite found in the Brazilian diamond and the speculation about an ocean larger than all of those on the surface "down there somewhere" is more interesting to me.

Perspective and humility -- there is A LOT that we don't know and have a heck of a time trying to even begin to figure out how we can know. ( have any ideas on how to drill a 660 mile deep well? )
