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.

Iron isotope systematics during igneous differentiation in lavas from Kīlauea and Mauna Loa, Hawai'i
Iron isotope and hafnium data from Kīlauea and Mauna Loa lavas reveal how igneous differentiation and mantle source heterogeneity shape Hawaiian volcanism.
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 …
