Briefings

A 2026 article suggests Earth's core may have leaked hydrogen into the mantle for billions of years, potentially influencing volcanic activity. The evidence describes Earth's formation, the cooling of the metallic core into the mantle, and the current process of mantle plumes rising to produce volcanic lava containing deep hydrogen.

Key points

• Volcanic eruptions can produce lava containing hydrogen derived from deep inside the planet.
• This hydrogen originates from the Earth's core, which was wrapped in a global ocean of molten rock during formation.

Context

The article proposes that ancient core leakage into the mantle could explain volcanic hydrogen sources, though the evidence is limited to geological formation and current plume activity.

Limitations

Evidence is limited to geological formation and current plume activity; no dates, units, or causal claims are supported.
