World's Oldest Rocks Found

Posted by timothy on from the and-jagger-wants-'em-back dept.

Smivs writes "The BBC reports that Earth's most ancient rocks, with an age of 4.28 billion years, have been found on the shore of Hudson Bay, Canada. Writing in Science journal, a team reports finding that a sample of Nuvvuagittuq greenstone is 250 million years older than any rocks known. It may even hold evidence of activity by ancient life forms. If so, it would be the earliest evidence of life on Earth — but co-author Don Francis cautioned that this had not been established. 'The rocks contain a very special chemical signature — one that can only be found in rocks which are very, very old,' he said."

    Shut the fuck up! Both candidates cling to religion for as long as it is expedient. It makes no difference, so your point is moot. Not even to mention you are feeding a probable troll on a discussion that should be about FUCKING GEOLOGY and not FUCKING BULLSHIT POLITICS!

    I'm saying it because we don't. If the neodymium formed by an exploding star, than this means a star exploded 4.28 billion years ago.

    How do these tests conclude anything about the age of the earth?

    (I would really like to know)
