A 36-million-year cycle of marine biodiversity booms and busts matches the movements of plate tectonics, linking what happens deep below the ocean to what’s happening in it.
Computational models of the composition and volumes of magmas during continental rifting evolution provide clues on the heterogeneities of the deep melting mantle.
The Emerald Isle has far fewer earthquakes than neighboring Britain. Now scientists think they know why.
A mysterious seismic feature at the bottom of Earth’s mantle is more widespread than previously thought.
The mantle’s resistance to flow appears different for glacial and plate tectonic timescales but this behavior can be reconciled with new thermo-mechanical models of the asthenosphere.
The 4.5-billion-year record contained in Earth’s continental crust reveals a seven-phase evolution, from an initial magma ocean to the present-day environment in which we live.
Seafloor spreading organized lithospheric minerals into a lattice, but small-scale convection jumbled up the innermost layer.
A new study suggests that carbonatite metasomatism, not silicate metasomatism as previously thought, was dominant prior to the removal of the North China Craton in the early Cretaceous.
Rocks stretch, break, and flow, depending on how and under which conditions they are loaded. A new formulation to better capture Earth’s rheology is explored in the context of plate thickness.
