Gold leak from Earth's core uncovered by researchers
Scientists have discovered that tiny amounts of gold and other precious metals are making their way from Earth's core up to the surface. By analyzing volcanic rocks from Hawaii, they found evidence that challenges the old idea that our planet's core is totally sealed off.
Evidence found in Hawaiian lava rocks
Researchers spotted a unique chemical fingerprint—ruthenium isotopes—in Hawaiian lava rocks. Since this signature is consistent with a core origin, it suggests metals like gold are traveling upwards through volcanic activity over millions of years.
Changes our understanding of Earth's formation
This slow leak of metals changes what we know about how Earth formed and how valuable elements get distributed. You can't exactly mine these deep resources anytime soon, but it gives scientists a new window into how our planet works beneath our feet.
