Melting of recycled ancient crust responsible for the Gutenberg discontinuity
The seismic Gutenberg discontinuity has long been associated with the lithosphere-asthenosphere boundary, yet the physical explanation of what is causing the discontinuity remains debated. Here, the authors report geochemical evidence, including Mg isotopes, and suggest that melting of recycled crus...

| Summary: | The seismic Gutenberg discontinuity has long been associated with the lithosphere-asthenosphere boundary, yet the physical explanation of what is causing the discontinuity remains debated. Here, the authors report geochemical evidence, including Mg isotopes, and suggest that melting of recycled crust is responsible for the Gutenberg discontinuity. |
