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.

Evidence of Volatile‐Induced Melting in the Northeast Asian Upper Mantle
Journal of Geophysical Research: Solid Earth, 2021 A seismic low velocity layer (LVL) above the mantle transition zone (MTZ), often thought to be caused by volatile‐induced melting, can significantly modulate planetary volatile cycles.

Effects of Composite Rheology on Plate‐Like Behavior in Global‐Scale Mantle Convection
Geophysical Research Letters, 2023 Earth's upper mantle rheology controls lithosphere‐asthenosphere coupling and thus surface tectonics. Rock deformation experiments and seismic anisotropy measurements indicate that composite rheology (co‐existing diffusion and dislocation creep) occurs ...

THE STRUCTURE OF LOW-VELOCITY ZONES IN THE MANTLE OF THE NORTHERN EUROPE
Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2015 The areas of low-velocity middle mantle shift into the transition zone are distinguished according to 3-d P-velocity model of the Fennoscandian shield mantle and its surroundings using Taylor approximation method.

Mid-mantle deformation inferred from seismic anisotropy [PDF]
, 2002 With time, convective processes in the Earth's mantle will tend to align crystals, grains and inclusions. This mantle fabric is detectable seismologically, as it produces an anisotropy in material properties—in particular, a directional dependence in ...

Seismic Structure of the Upper Mantle Beneath Eastern Asia From Full Waveform Seismic Tomography
Geochemistry Geophysics Geosystems, 2018 To better understand the subsurface behavior of subducting slabs and their relation to the tectonic evolution of the overriding plate, we conduct a full waveform inversion on a large data set to determine a high‐resolution seismic model, FWEA18 (Full ...

Depth-dependent density change within the continental upper mantle
Contributions to Geophysics and Geodesy, 2012 The empirical model of the depth-dependent density change within the upper continental mantle is derived in this study. The density of the upper(most) mantle underlying the continental crust is obtained from the estimated values of the crust–mantle (Moho)

Slab–mantle interaction, carbon transport, and kimberlite generation in the deep upper mantle
Earth and Planetary Science Letters, 2019 Low-degree partial melts from deeply subducted, carbonated ocean crust are carbonatite liquids with ∼35–47 wt% CO2. Their reactions with the overlying mantle regulate the slab–mantle interaction and carbon transport in the deep upper mantle but have not ...
