Earth’s core holds most of its gold, with some material leaking into the mantle

A groundbreaking study reveals that Hawaiian volcanic rocks contain core material, lending weight to a previously held theory about Earth’s structure. This finding indicates that the core engages in more exchange with the mantle than previously thought, particularly evidenced by ruthenium isotopes. The research highlights the substantial flow of mantle material from the core-mantle boundary to the surface, fundamentally enhancing our grasp of the Earth’s deep interior dynamics.
