Rarest rock discovered from India

German geologists Thursday said they have discovered in India one of the world's rarest rocks, dating back to the birth of the planet when the Earth was covered with a hot ocean of melted stone.

The fragment from the primeval crust is only the second ever discovered, said scientists at the University of Muenster.

Only the second piece ever discovered. Wow, I'll bet this piece-o-rock is worth millions. Two pieces found, one in India, one in Canada, there must be some pieces left somewhere in between? I've been looking for a picture of this ancient rock all over the net and can't find any. Maybe somebody else out there has come up with one and can post. I sure would be interested to see what this rare rock looks like.

Forgive if already posted...didn't see it.

don't let the twinkie company hear about this! they're gonna be so jealous. preservations lasting billions instead of millions. i bet they're up to something already.

just adding

The upper part of the mantle is composed mostly of peridotite. A peridotite is a dense, coarse-grained igneous rock, consisting mostly of the minerals olivine and pyroxene. Peridotite is ultramafic and ultrabasic, as the rock contains less than 45% silica....
, a rock denser than rocks common in the overlying crust. The boundary between the crust and mantle is conventionally placed at the Mohorovicic discontinuity

That's nothing.
I have a fruitcake that's older than that.

Perhaps this is the same thing:

That is the second of the two known pieces....the first one found.
At least there's a photograph of that one...Thanks.

the rock may be rare but i seriously doubt their assumptions of it's age and it's origins

i just dont put much faith into their "assumptions" or "pseudo-facts" anymore

don't blame me though, it was their fault for talking up their finds to increase funding, etc

Why?

I find it eminently plausible.

It's an interesting find. I don't think they will find much in between the two discoveries however, given the nature of plate tectonics.

It's lovely though. Everything gets recycled in the end

wait
no pictures?
superb job done here.
