★ New research discovers that the gold and precious elements we see today may have originally come from a a bombardment of meteorites more than 200 million years after Earth was formed.
★ During the formation of Earth, molten iron sank to its centre to make the core.
★ This took with it the vast majority of the planet's precious metals -- such as gold and platinum.
★ In fact, there are enough precious metals in the core to cover the entire surface of Earth with a four-metre thick layer.
★ Then how come we find gold and other precious elements on Earth's mantle noticeably more than expected as most has sunk to the core ?
★ The answer is, it has come from a meteorite shower that hit Earth after the core formed. The full load of meteorite gold was thus added to the mantle alone and not lost to the deep interior.
