Spreading ridge migration enabled by plume-ridge de-anchoring
Numerical modelling shows that high-buoyancy mantle plumes can capture and de-anchor spreading ridges, enabling their migration over vast distances.

Nicolas Coltice uses 3D spherical numerical geodynamic models to study how mantle convection drives plate tectonics, treating the mantle-lithosphere as a single coupled system.
Unravelling the origins of volcanism along Eastern Australia and the Tasman Sea
Mantle plumes are buoyant upwellings rising from the Earth’s core-mantle boundary to its surface, generating hotspot chains that track the direction of plate motion. Eastern …
Parallel volcanic chains generated by plume-slab interaction (invited)
Deep mantle plumes are buoyant upwellings rising from the Earth’s core-mantle boundary to its surface, and describing most hotspot chains. Mechanisms to explain dual chains of …
Slab-induced plume branching connects parallel hotspot chains
We propose that slab-induced plume branching can explain the formation of parallel hotspot chains observed in the oceanic and continental record. Using plate tectonic …
