The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 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.

Geochemistry, Geophysics, Geosystems, 2021 Lavas that have erupted at near‐axis seamounts provide windows into mid‐ocean ridge mantle heterogeneity and melting systematics which are not easily observed on‐axis at fast‐spreading centers.

Bulletin of the Mineral Research and Exploration, 2022 The highly siderophile element (HSE) or platinum group element (PGE) and Os isotope systematics of basaltic volcanics have recently received a significant attention because of their potential to constrain the petrological processes on magma generation ...

Configurational entropy of basaltic melts in Earth’s mantle [PDF]
Proceedings of the National Academy of Sciences, 2020 Significance Proper inference of the seismological and chemical effects of partial melting in Earth’s upper mantle depends on physical properties of interstitial melts at elevated pressure. Silicate liquids display anomalous softening upon compression.

Melting and defect transitions in FeO up to pressures of Earth’s core-mantle boundary
Nature Communications, 2023 The high-pressure melting curve of FeO controls key aspects of Earth’s deep interior and the evolution of rocky planets more broadly. However, existing melting studies on wüstite were conducted across a limited pressure range and exhibit substantial ...

Fossilized Melts in Mantle Wedge Peridotites [PDF]
Scientific Reports, 2018 AbstractThe shallow oxidized asthenosphere may contain a small fraction of potassic silicate melts that are enriched in incompatible trace elements and volatiles. Here, to determine the chemical composition of such melt, we analysed fossilized melt inclusions, preserved as multiphase solid inclusions, from an orogenic garnet peridotite in the Bohemian ...

Quartz-bearing rhyolitic melts in the Earth’s mantle
Nature Communications, 2022 AbstractThe occurrence of rhyolite melts in the mantle has been predicted by high pressure-high temperature experiments but never observed in nature. Here we report natural quartz-bearing rhyolitic melt inclusions and interstitial glass within peridotite xenoliths.

Geochemistry Geophysics Geosystems, 2019 The mechanisms sustaining basaltic continental intraplate volcanism remain controversial. Continental intraplate volcanism is often geographically associated with slab stagnation in the mantle transition zone (MTZ), for example, in eastern Asia, central ...
