Pyroclastic density currents (PDCs) are hot, density-driven fast-moving flows of gas, rock and ash produced by volcanic events such as explosive eruptions, the fallback of eruption columns or the collapse of lava domes. They are deadly geological haz... Read More about Characterisation of reverse grading in ignimbrites through image analysis and experimental granular currents.

Simultaneous fall and flow during pyroclastic eruptions: A novel proximal hybrid facies (2022)
Journal Article
Dowey, N., & Williams, R. (2022). Simultaneous fall and flow during pyroclastic eruptions: A novel proximal hybrid facies. Geology, 50(10), 1187-1191. https://doi.org/10.1130/G50169.1

The deposits of Plinian and subplinian eruptions provide critical insights into past volcanic events and inform numerical models that aim to mitigate against future hazards. However, pyroclastic deposits are often considered from either a fallout or... Read More about Simultaneous fall and flow during pyroclastic eruptions: A novel proximal hybrid facies.

Geology Uprooted! Decolonising the Curriculum for Geologists (2022)
Journal Article
Rogers, S. L., Dowey, N., Lau, L., Sheikh, H., & Williams, R. (2022). Geology Uprooted! Decolonising the Curriculum for Geologists. Geoscience Communication, 5(3), 189–204. https://doi.org/10.5194/gc-2021-35

Geology is colonial. It has a colonial past and a colonial present. Most of the knowledge that we accept as the modern discipline of geology was founded during the height of the post-1700 European empire's colonial expansion. Knowledge is not neutral...

Expedition 391 Preliminary Report : Walvis Ridge Hotspot: drilling Walvis Ridge, Southeast Atlantic Ocean, to test models of ridge hotspot interaction, isotopic zonation, and the hotspot reference frame (2022)
Report
Widdowson, M., Sager, W., Hoernle, K., Höfig, T. W., Avery, A. J., Bhutani, R., …Tshiningayamwe, M. (2022). Expedition 391 Preliminary Report : Walvis Ridge Hotspot: drilling Walvis Ridge, Southeast Atlantic Ocean, to test models of ridge hotspot interaction, isotopic zonation, and the hotspot reference frame. International Ocean Discovery Program (IODP)

Hotspot tracks (quasilinear chains of seamounts, ridges, and other volcanic structures) provide important records of plate motions, as well as mantle geodynamics, magma flux, and mantle source compositions. The Tristan-Gough-Walvis Ridge (TGW) hotspo...

Diachronous end-Permian terrestrial ecosystem collapse with its origin in wildfires (2022)
Journal Article

The Permian-Triassic Mass Extinction (PTME) is the greatest biodiversity crisis in Earth history and while the marine crisis is increasingly well constrained, the timing and cause(s) of terrestrial losses remain poorly understood. There have been sug... Read More about Diachronous end-Permian terrestrial ecosystem collapse with its origin in wildfires.

Volcanically-Induced Environmental and Floral Changes Across the Triassic-Jurassic (T-J) Transition (2022)
Journal Article

The End-Triassic Mass Extinction (ETME) saw the catastrophic loss of ca. 50% of marine genera temporally associated with emplacement of the Central Atlantic Magmatic Province (CAMP). However, the effects of the ETME on land is a controversial topic.... Read More about Volcanically-Induced Environmental and Floral Changes Across the Triassic-Jurassic (T-J) Transition.

Correlating deformation events onshore and offshore in superimposed rift basins: The Lossiemouth Fault Zone, Inner Moray Firth Basin, Scotland (2022)
Journal Article

Correlating deformation events onshore and offshore in superimposed rift basins: The Lossiemouth Fault Zone, Inner Moray Firth Basin, Scotland. Basin Research, https://doi.org/10.1111/bre.12661

The separation and characterisation of different deformation events in superim-posed basins can be challenging due to the effects of overprinting and/or fault reactivation, combined with a lack of detailed geological or geophysical data. This paper s... Read More about Correlating deformation events onshore and offshore in superimposed rift basins: The Lossiemouth Fault Zone, Inner Moray Firth Basin, Scotland.
