Marine Anoxia and Ocean Acidification During the End‐Permian Extinction
Geophysical Monograph Series, Page 325-340., 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.

Narrow, Fast, and “Cool” Mantle Plumes Caused by Strain‐Weakening Rheology in Earth's Lower Mantle
Geochemistry, Geophysics, Geosystems, 2022 The rheological properties of Earth's lower mantle are key for mantle dynamics and planetary evolution. The main rock‐forming minerals in the lower mantle are bridgmanite (Br) and smaller amounts of ferropericlase (Fp).

Mantle dynamics and seismic tomography [PDF]
Proceedings of the National Academy of Sciences, 2000 Three-dimensional imaging of the Earth's interior, called seismic tomography, has achieved breakthrough advances in the last two decades, revealing fundamental geodynamical processes throughout the Earth's mantle and core. Convective circulation of the entire mantle is taking place, with subducted oceanic lithosphere sinking into the lower mantle,

Geophysical and geochemical constraints on geoneutrino fluxes from Earth's mantle [PDF]
, 2012 Knowledge of the amount and distribution of radiogenic heating in the mantle is crucial for understanding the dynamics of the Earth, including its thermal evolution, the style and planform of mantle convection, and the energetics of the core.

Modeling Mantle Dynamics in the Banda Sea Triple Junction – Exploring a Possible Link to El Niño Southern Oscillation (Revisited) [PDF]
Journal of Systemics, Cybernetics and Informatics, 2020 The upwelling mantle within the Banda Sea is modeled using computer visualization techniques. The Banda Sea is considered a triple junction of the Pacific, Australian, and Eurasian Plates within the plate tectonic hypothesis.

Multi‐Layer Seismic Anisotropy Beneath Greenland
Geochemistry, Geophysics, Geosystems, 2021 Seismic anisotropy provides insight into past episodes of lithospheric deformation and the orientations of strain in the underlying asthenosphere. The Greenland mantle has played host to a rich history of tectonic processes, including multiple orogenies ...

Impact of upper mantle convection on lithosphere hyperextension and subsequent horizontally forced subduction initiation [PDF]
Solid Earth, 2020 Many plate tectonic processes, such as subduction initiation, are embedded in long-term (>100 Myr) geodynamic cycles often involving subsequent phases of extension, cooling without plate deformation and convergence. However, the impact of upper mantle
