Linking deep mantle heat and helium isotopes in the Iceland plume

Puntos clave

• Helium isotopes show a strong correlation with deep mantle heat variations.
• Analysis across volcanic sites reveals geochemical signatures indicating plume dynamics.
• Observational analysis using geophysical data confirms the connection between thermal anomalies and volcanism.
• Findings support the theory that helium isotopes can trace the origins of mantle processes.
