For the first time, geologists have traced rare helium-3 isotopes and precious metals like gold and platinum in volcanic rocks on Hawaii’s Big Island—suggesting material is leaking from the Earth's core through deep mantle plumes. This discovery challenges long-standing beliefs that the core is geochemically isolated from the rest of the planet. If proven consistent, these leaks could unlock new insights into Earth’s formation, its ongoing evolution, and even how elements crucial to technology and life arrived at the surface. #GeologyBreakthrough #EarthsCore #GoldDiscovery #HawaiiVolcano #RareMetals
