The final 10 Myr of the Paleozoic saw two of the biggest biological crises in Earth history: the middlePermian extinction (often termed the Guadalupian–Lopingian extinction [GLE]) that was followed 7–8 Myr later by Earth's most catastrophic loss of d...

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...

Journal Article

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.

The nature and significance of rift-related, near-surface fissure fill networks in fractured carbonates below regional unconformities (2020)
Journal Article
Hardman, K., Holdsworth, R. E., Dempsey, E., & McCaffrey, K. (2020). The nature and significance of rift-related, near-surface fissure fill networks in fractured carbonates below regional unconformities. Journal of the Geological Society, https://doi.org/10.1144/jgs2020-074

Hosted in carbonate and crystalline basement rocks below regional unconformities, fissure-fill networks are a widely recognized, but relatively little described near-surface phenomenon (< 1-2km). Faults and fractures in otherwise tight Devonian carbo...

A bedform phase diagram for dense granular currents (2020)
Journal Article
Smith, G., Rowley, P., Williams, R., Giordano, G., Trolese, M., Silleni, A., Parsons, D. R., & Capon, S. (2020). A bedform phase diagram for dense granular currents. Nature communications, 11(1), Article 2873. https://doi.org/10.1038/s41467-020-16657-z

Pyroclastic density currents (PDCs) are a life-threatening volcanic hazard. Our understanding and hazard assessments of these flows rely on interpretations of their deposits. The occurrence of stratified layers, cross-stratification, and bedforms in... Read More about A bedform phase diagram for dense granular currents.

Late Ordovician mass extinction caused by volcanism, warming, and anoxia, not cooling and glaciation (2020)
Journal Article
Bond, D. P., & Grasby, S. E. (2020). Late Ordovician mass extinction caused by volcanism, warming, and anoxia, not cooling and glaciation. Geology, 48(8), 777-781. https://doi.org/10.1130/G47377.1

The Ordovician saw major diversification in marine life abruptly terminated by the Late Ordovician mass extinction (LOME). Around 85% of species were eliminated in two pulses 1 m.y. apart. The first pulse, in the basal Hirnantian, has been linked to... Read More about Late Ordovician mass extinction caused by volcanism, warming, and anoxia, not cooling and glaciation.

Earthquake nucleation in the lower crust by local stress amplification (2020)
Journal Article

Deep intracontinental earthquakes are poorly understood, despite their potential to cause significant destruction. Although lower crustal strength is currently a topic of debate, dry lower continental crust may be strong under high-grade conditions....

Hosting up to 3.3 billion barrels of oil in place, the upfaulted Precambrian crystalline rocks of the Lancaster field, offshore west of Shetland, give key insights into how fractured hydrocarbon reservoirs can form in such old rocks. The Neoarchean (... Read More about The nature and age of basement host rocks and fissure fills in the Lancaster field fractured reservoir, West of Shetland.
