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 …
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, …
