Here, we used the first whole-mantle 3D attenuation model to interpret the longevity & viscosity of the large low velocity provinces (LLSVPs). To explain our observations the #LLSVPs need to be not only hotter but also have larger mineral grains, in contrast to their surroundings

We used the 3D attenuation model I created to interpret the longevity and viscosity of the large low shear velocity provinces (LLSVPs). To explain our observations the #LLSVPs need to be not only hotter but also have larger mineral grains, in contrast to their surroundings 2/3

Very excited to share the culmination of a 5-year journey, now published in @nature.com. We built the first-ever 3D attenuation model for the whole mantle! This was a collaboration between @uugeo.bsky.social, @mitpress.bsky.social and @vassar.bsky.social!

Great new Nature paper from my Utrecht seismology colleagues on the physical properties of the enigmatic LLSVPs!
