Topic: Chunk of original earth found

Pocket of rock survived 4.5 billion years without being mixed by plate tectonics

Imagine you suddenly discovered part of your umbilical cord was still attached. Scientists just did that for the planet Earth. What's been found is a clear sign that beneath the crust in northern Canada there is a chunk of pristine, undisturbed rock from the time when Earth was nothing but molten rock.

The evidence comes in the form of lava rocks that, themselves, are a mere 60 million years old. But these rocks contain an early Earth mixture of helium, lead and neodymium isotopes which suggest the mantle rock beneath the crust that yielded them is a virgin pocket of Earth's original material.

OMG this is amazing news!  Oh wait, no it isn't.  

Well, maybe sirean will be excited.

As a guy who watches documentaries regularly, I do find this exciting.

I'd like to be the first guy to carve my name into that "undisturbed" rock.

I'm an ancient history buff and for some reason I'm, not that excited about this. I mean, it's nice to know there's a place on the planet that's untouched by humans, until now anyway, but it's like finding a dusty corner of your room that's been neglected for ages and the most common remark is "wow, look how much dust has piled up!"

There'll be a Macdonalds on top of there sooner or later
