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 …
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 …
Exploring the interaction between mantle plumes and subducting slabs in the Tasman Sea region, focusing on the three parallel hotspot tracks — Tasmantid, Lord Howe, and Cosgrove — …
Investigating the link between changes in subducting slab flux and the triggering of intraplate volcanism, with a focus on the volcanic record of eastern Australia.
Intraplate volcanism triggered by subducted volatiles during bursts in slab flux
Intraplate volcanism triggered by the release of subducted volatiles during bursts in slab flux
Partial melting of ancient subducted slabs provide a framework through which to explain non-age progressive volcanism in a region of anomalous mantle composition.
“Eastern Australia and Zealandia host widespread volcanic activity including both age-progressive hotspot chains and enigmatic lava field eruptions with no clear time dependence. …
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, …
