    I like epi-volcanic atolls, but at times, they find themselves being subducted to the depths of the Earth. That puts a lot of carbon into the asthenosphere and accelerates CO2-rich arc magma ascent (and maybe restarts the cycle).

    A #Subduction zone is a geological area where two tectonic plates collide, and one plate sinks or "subducts" beneath the other and is forced into the Earth's mantle.

    This process is a result of density differences between the two plates and can trigger powerful #Earthquakes, volcanic eruptions, and #Tsunamis.

    Sorena Sorensen passed away this month.

    Sorena was a long-time curator at the National Museum of Natural History of the Smithsonian Institution. She was also an insightful and talented researcher who studied the role of fluids in metamorphism of subduction-related rocks. She also contributed to understanding the formation of jadeite and jade deposits.

    At high pressures, fluorine-free topaz is stable: Topaz-OH. It's likely present only on recent Earth in our solar system: water, aluminous sediments (shales; pelites) from continental crust and cold subduction zones are all required.

    Given these, Topaz-OH can potentially transport water into the mantle transition zone (where it's stored in ) Figure from Huang et al (2020).

    Congratulations to Dr. Meghomita Das, who successfully defended her PhD thesis on the structure of a preserved subduction plate interface on Angel Island, San Francisco Bay.

    Retrouvez le blog de la campagne en mer MANTA-RAY : dans la région des Petites Antilles, la plaque #Caraïbe chevauche les plaques Nord et Sud américaines. Ce phénomène de chevauchement est nommé « #subduction », et est responsable de la sismicité très active de la région. D’une manière générale, près de 90 % des #séismes qui ont lieu sur terre sont dû à des phénomènes de subduction.

    #lesaviezvous ? lors de la campagne #océanographique SUPER-MOUV sur la zone de #subduction des Andes-Nord, au large de #Pedernales en #Equateur et avec l'aide technique des membres à bord du Pourquoi Pas ? #IFREMER, des créneaux de mise à disposition de la bande passante du navire ont été libérés pour la tenue de visioconférences entre les #scientifiques à bord et des Lycées (Val d'Argens du Muy en France; Claudel d'Ottawa au Canada) grâce à #Edumed
