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, …
Unravelling the origins of enigmatic volcanism to discover critical metals
This talk explores the origins of enigmatic intraplate volcanism that occurs far from plate boundaries, and its implications for discovering critical metal deposits. By integrating …
UTas Maydena workshop
Workshop presentation at the University of Tasmania exploring geodynamic and geophysical research themes relevant to the geology of Tasmania and southeastern Australia.
The role of plume-ridge decoupling on rapid plate motion and intraplate volcanism
Mantle plumes and mid-ocean ridges interact in ways that influence both plate motion and volcanism, yet these dynamics are poorly captured in existing plate tectonic models. We …
Geodynamic modelling update
This talk presents an update on geodynamic modelling efforts focused on understanding the origins of intraplate volcanism in eastern Australia. We discuss recent advances in …
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 …

Eruption and disuption: how Earth's deep interior and surface communicate
The origin of intraplate mafic volcanism along the eastern margin of Australia
The eastern margin of Australia has experienced extensive mafic volcanism since its breakaway from Antarctica (~ 80 Ma). A plume origin has been suggested for intraplate volcanism, …
