New paper alert! James Day et al. report on the geochemistry and Os-isptopes of lavas from the 2021 #CumbreVieja eruption on #LaPalma, #CanaryIslands πŸŒ‹πŸŒ‹πŸŒ‹ Read about it here:… #OpenAccess

New paper in EPSL by James Day et al. entitled "Mantle source characteristics and magmatic processes during the 2021 La Palma eruption".

Check out the beautiful #LaPalma lavas that were analysed in this study. The paper features a ton of geochemistry on these including major & trace elements, Os-Re isotopes, and olivine oxybarometry πŸ’ŽπŸ”¬

Here is a cartoon of the magma system that we envisaged based on the data. The latest eruption probably followed a somewhat similar magmatic progression to the 1949 and 1971 eruptions πŸŒ‹

Cheers πŸ™Œ to the author team, led by James Day at Scripps, USA πŸ‡ΊπŸ‡Έ with folks from institutions in Sweden, Spain, Germany, and the Canary Islands. And big thanks to the reviewers for helpful input.
