Geophysical Monograph Series, Page 1-26., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Vanadium Isotopic Compositions of the High‐3He/4He Baffin Island Lavas
Geochemistry, Geophysics, GeosystemsThe isotopic composition of vanadium (V) in hotspot lavas provides new insight into the source of deep mantle heterogeneities. We measured V isotopic compositions in Paleogene Baffin Island lavas, which erupted above the Iceland plume head, to constrain ...

Geochemistry, Geophysics, Geosystems, 2021 The flow of high‐temperature and compositionally enriched material between mantle plumes and nearby spreading centers influences up to 30% of the global mid‐ocean ridge system and represents a significant, but currently unconstrained, flux of volatiles ...

Plume–ridge interactions: ridgeward versus plate-drag plume flow [PDF]
Solid Earth, 2023 The analysis of mid-ocean ridges and hotspots that are sourced by deep-rooted mantle plumes allows us to get a glimpse of mantle structure and dynamics.

Nature Communications, 2023 Discovering ancient mantle plumes is challenging. By combining electrical conductivity with mineral physics modelling, this work finds a remnant of an ancient plume trapped in the mantle transition zone and sheds new light on mantle plume physics.

Robust Seismic Images of the Hawaiian Plume
Geophysical Research Letters, 2022 To image the Hawaiian plume and the plume‐lithosphere interaction, we determine a robust 3‐D shear‐wave velocity (Vs) model of the upper mantle and the mantle transition zone (MTZ) beneath Hawaii by jointly inverting teleseismic S‐wave arrival times ...

Geophysical Research Letters, 2022 N–S rifting is one of the most typical tectonics in southern Tibet, but its formation mechanism remains controversial. Geophysical observations indicated spatial correlations between rifts and lithospheric mantle anomalies, presumably caused by ...

Proceedings of the National Academy of Sciences, 2013 Volcanoes are usually found near the borders of tectonic plates that are violently either pushing or pulling at each other. Mysteriously, however, volcanoes sometimes erupt in the middle of these plates instead. The culprits behind these outbursts might be giant pillars of hot molten rock known as mantle plumes, jets of magma rising up from near the ...

Tracing the Iceland plume and North East Atlantic breakup in the lithosphere
Communications Earth & Environment, 2023 Plumes are domains where hotter material rises through Earth´s mantle, heating also the moving lithospheric plates that may experience thinning or even continental breakup.
