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.

Global Hydrogen Production During High-Pressure Serpentinization of Subducting Slabs
Quantifying global hydrogen production from high-pressure serpentinisation of subducting slabs over the last 5 million years.
Deep time spatio-temporal data analysis using pyGPlates with PlateTectonicTools and GPlately
GPlately: a Python interface for deep-time spatio-temporal data analysis using pyGPlates, simplifying plate tectonic reconstructions.
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 …
