Copyright © 2020 the Author(s). Published by PNAS. Tibet's ancient topography and its role in climatic and biotic evolution remain speculative due to a paucity of quantitative surface-height measurements through time and space, and sparse fossil reco...

The Hawaii-Emperor and Louisville seamounts form the two most prominent time-progressive hotspot trails on Earth. Both formed over a similar time interval on lithosphere with a similar range of ages and thickness. The Hawaii-Emperor seamounts are lar...

Fracture attribute scaling and connectivity datasets from analogue systems are widely used to inform sub-surface fractured reservoir models in a range of geological settings. However, significant uncertainties are associated with the determination of...

We measured the concentrations of trace elements in Late Permian to Early Triassic sediments from Spitsbergen. High mercury concentrations in sediments from the level of the Permo-Triassic Mass Extinction (PTME) at this location were previously attri...

Stress fields of ancient seismicity recorded in the dynamic geometry of pseudotachylyte in the Outer Hebrides Fault Zone, UK (2020)
Journal Article
Campbell, L., Lloyd, G., Phillips, R., Walcott, R., & Holdsworth, R. (2021). Stress fields of ancient seismicity recorded in the dynamic geometry of pseudotachylyte in the Outer Hebrides Fault Zone, UK. Journal of the Geological Society, 178(1), Article jgs2020-101. https://doi.org/10.1144/jgs2020-101

Heterogeneous sequences of exhumed fault rocks preserve a record of the long-term evolution of fault strength and deformation behaviour during prolonged tectonic activity. Along the Outer Hebrides Fault Zone (OHFZ) in NW Scotland, numerous pseudotach...

Size variations in foraminifers from the early Permian to the Late Triassic: Implications for the Guadalupian-Lopingian and the Permian-Triassic mass extinctions (2020)
Journal Article

A bigger splat: The catastrophic geology of a 1.2-b.y.-old terrestrial megaclast (2020)
Journal Article
Killingback, Z., Holdsworth, R. E., Walker, R. J., Nielsen, S., Dempsey, E., & Hardman, K. (2020). A bigger splat: The catastrophic geology of a 1.2-b.y.-old terrestrial megaclast. Geology, https://doi.org/10.1130/G48079.1

Rockfalls are relatively little described from the ancient geological record, likely due to their poor preservation potential. At Clachtoll, northwest Scotland, a megaclast (100 m × 60 m × 15 m) of Neoarchean Lewisian gneiss with an estimated mass of...

The Permian-Triassic mass extinction, the greatest biotic crisis in Earth history, triggered the complete replacement of ecosystems with the 5–10% surviving species giving rise to the Mesozoic fauna. Despite a long history of systematic studies on Pe... Read More about Migration controls extinction and survival patterns of foraminifers during the Permian-Triassic crisis in South China.
