Tracking deep mantle heat and volatiles in the Iceland plume from a high-density survey of helium isotopes along the Reykjanes Ridge

Key Points

• The analysis indicates that helium isotopes provide a clear insight into mantle dynamics and source processes.
• A notable finding was the variation of helium isotopes along the Reykjanes Ridge, which underscores deep mantle influences.
• Observational analysis across a high-density survey of helium isotopes was employed in this study to track mantle activities.
• This research highlights the intricate relationship between deep mantle heat and volatile elements, warranting further exploration.
