Seismic imaging of lithospheric structure and the onset of melting beneath Galapagos

Kate Rychert and Nick Harmon have a new paper published in Earth and Planetary Science Letters about seismic imaging of crust and mantle discontinuity structure beneath the Galapagos Archipelago. They image a lithosphere-asthenosphere boundary that is too thick to be consistent with a thermally defined plate, indicating a compositional component. They also image discontinuities related… Read More Seismic imaging of lithospheric structure and the onset of melting beneath Galapagos

Understanding the structure and dynamics of the lithosphere-asthenosphere system

A workshop on the structure and dynamics of the lithosphere-asthenosphere system was organized at the College de France, Paris, from 19-20 November 2013. The primary focus of the workshop was to enhance understanding of the dynamics interaction between the colder, more brittle lithosphere and the warmer, more ductile asthenosphere by combining constraints from observations and… Read More Understanding the structure and dynamics of the lithosphere-asthenosphere system
