Hadean isotope signature in recently erupted rocks (Nature article)
Is this as sensational as it sounds? I’m not a geologist myself but from what I’ve gathered, the rocks erupted at the Fani Maoré submarine volcano appear to be sourced from mantle material with Hadean (lava ocean) brigmanite in it, suggesting a more heterogenous mantle than previosuly believed. This is based on isotope data.
