Skip to comments.Arctic rocks shed light on ancient Earth's inner workings

Geochemists studying Arctic rocks say they have found evidence of ancient rock from the interior of the Earth that is nearly as old as the planet itself.
Such material gives scientists an idea of what the mineral structure of the inner Earth used to look like billions of years ago and may force them to adjust their theories about the evolution of the planet's structure over the eons, said Matthew Jackson, a geochemist at Boston University and lead author of the paper.

the arctic rocks.
“may force them to adjust their theories”
Aha - unexpected rocks.
Who really cares? A rock is a rock.
This is actually pretty neat. Every so often new evidence comes up concerning our past and it can have a “butterfly effect” on the scientific community.
ancient ? aren’t they all ?

A rock is an interesting marker of geologic formation or something to put in a boy’s slingshot.

This rock doesn’t exist, because rocks that old weren’t in the bible!
Odd phrase, that.
Reminds me of the classic line from The Phantom Toolbooth:
"For, while it was not quite square, it was definitely not round, and for its size it was larger than almost any other big package of smaller dimension that he'd ever seen."
Except for the newer digital rocks.
This just in . . . . The CRU says with “high confidence” that these rocks emerged because of increased CO2 levels and global warming. If levels aren’t reduced we can expect more and more mantle spew, which hits women and minorities hardest . . . .

Oh, Yeah? What if they discovered the earth was made out of solid GOLD!!!
