How mantle plumes steer spreading ridges
Our paper in Nature Communications reveals a new mechanism for mid-ocean ridge migration: plumes with high buoyancy flux can capture and anchor ridges in place, and when they wane, …
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.
The isotopic origin of Lord Howe Island reveals secondary mantle plume twinning in the Tasman Sea
First radiogenic isotope data from Lord Howe Island lavas reveal a secondary mantle plume twin in the Tasman Sea with a distinct deep mantle source.
