Earth's Core Leak Revealed through Ancient Arctic Rocks

Recently Geochemists have made a surprising discovery about the Earth's core by analyzing 62-million-year-old Arctic rocks, uncovering compelling evidence of a slow leak from the planet's core. Scientists found record concentrations of helium isotopes in ancient Arctic rocks, suggesting a slow leak from Earth's core.

• The discovery was detailed in a research publication in Nature and is based on an analysis of ancient lava flow with high helium-3 concentrations.
• Researchers speculate that there may be reserves of this elusive gas buried approximately 2,900 kilometers underground. Helium, primarily from the Big Bang, was partially retained by the Earth during its formation, ....
