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.

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 …
