Icelandic Rocks Suggest Meteorites Brought Gold To Earth

sciencehabit writes "Gold, platinum, and other precioius metals were sucked into Earth's molten iron core soon after our planet formed. So where did all of the material for our fancy jewelry come from? According to high-precision measurements of two isotopes, or atomic variants, of tungsten in 4-billion-old rocks from Greenland published online today in Nature [the abstract adds a bit more; the full version is paywalled, though], precious-metal-bearing meteorites struck Earth around this time, coating the planet in a veneer containing gold, platinum, and other elements long after their native counterparts had disappeared into the planet's core."

    'Icelandic Rock' was ABBA's greatest rival in the late 70's. They did indeed bring much gold to earth.

    Iceland is very green. Greenland is full of ice. And never the twain shall meet, or be mixed up.

    I think you need to brush up on your mnemonic-writing skills.

    Iceland is greeny while Greenland is icy
    The latter is empty, the former's quite pricey..
