New Orleans Ernest N. Morial Convention Center in New Orleans, Louisiana (USA)

The largest Earth and Space science meeting in the world is taking place in New Orleans, Louisiana. As usual, once a year AGU gathers the best and brightest minds from around the globe in the pursuit of high quality science, knowledge, and a more sustainable future. In particular, AGU allows to share your science, advance your career, and gain visibility and recognition for your own scienti ...[Read More]

Going with the toroidal mantle flow

Subduction zones host one of the most complex and fascinating tectonic systems on the planet. Numerical models by Király and colleagues recently published in Earth and Planetary Science Letters reveal that the strength of the toroidal flow depends on the mantle viscosity and the magnitude of the slab pull force while the characteristic size of the toroidal cells mainly depends on the size of the c ...[Read More]

Thorsten Becker presents his keynote lecture on subduction dynamics

Let’s keep going with the programme: today’s talks dealt with the following topics: (1) Lower mantle rheology–what do we really know? (2) Modelling plasticity and fractures in porous media: everything goes wrong! (3) Complexities of subduction dynamics. The first keynote talk was on the rheology of the lower mantle, an important part of the Earth. John Hernlund spent his 45 min describing wh ...[Read More]

The sequence of events before continental crust formation has long been contested. Numerical simulations performed by Rozel and colleagues imply that the key to the puzzle could lie in the intrusive magmatism. Despite several decades of research on the topic, the trigger of proto-continental crust formation on early Earth remains an enigma. However, magmatic processes may hold the key to unravelli ...[Read More]
