Thesis
Johnston, T. (2022). How does grain size distribution impact the mobility and deposition of analogue pyroclastic density currents?. (Thesis). University of Hull. Retrieved from https://hull-repository.worktribe.com/output/4224880

Pyroclastic density currents (PDCs) are hot, density-driven flows of gas, rock and ash generated during explosive volcanic eruptions or from the collapse of lava domes. PDCs are able to travel for tens of km, traversing topographic barriers hundreds...

Mid-crustal reactivation processes linked to frictional melting and deep void development during seismogenic slip: examples from the Lewisian Complex, NW Scotland (2022)
Journal Article
Hardman, K., Holdsworth, R. E., Scott, L., Dempsey, E., & McCaffrey, K. J. W. (in press). Mid-crustal reactivation processes linked to frictional melting and deep void development during seismogenic slip: examples from the Lewisian Complex, NW Scotland. Journal of the Geological Society, https://doi.org/10.1144/jgs2022-037

Exhumed examples of ancient fault voids formed during seismic slip at depths > 10 km are well preserved in the Assynt Terrane of the Lewisian Complex, NW Scotland. They are interpreted to have formed during regional Mesoproterozoic (ca 1.55 Ga; ‘Assy...

Journal of the Geological Society, 180(2), Article jgs2022-076. https://doi.org/10.1144/jgs2022-076

Scottish ‘Newer Granites’ record the evolution of the Caledonides resulting from Iapetus subduction and slab breakoff during the Silurian–Devonian Scandian Orogeny, but relationships between geodynamics, petrogenesis and emplacement are incomplete. L... Read More about Caledonian hot zone magmatism in the ‘Newer Granites’: insight from the Cluanie and Clunes plutons, Northern Scottish Highlands.

Rapid marine oxygen variability: Driver of the Late Ordovician mass extinction (2022)
Journal Article
Kozik, N. P., Young, S. A., Newby, S. M., Liu, M., Chen, D., Hammarlund, E., …Owens, J. D. (2022). Rapid marine oxygen variability: Driver of the Late Ordovician mass extinction. Science Advances, 8(46), eabn8345. https://doi.org/10.1126/sciadv.abn8345

The timing and connections between global cooling, marine redox conditions, and biotic turnover are underconstrained for the Late Ordovician. The second most severe mass extinction occurred at the end of the Ordovician period, resulting in ~85% loss...

The end-Triassic (∼201 Mya) records one of the five largest mass extinction events of the Phanerozoic. Extinction losses were coincident with large igneous province volcanism in the form of the Central Atlantic Magmatic Province (CAMP) and major carb...

Marine redox conditions through the Permian-Triassic (P-T) boundary interval have been intensively studied in South China with different redox proxies and from different sections. However, the resultant interpretations are inconsistent and sometimes...

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)

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...
