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 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...

Journal Article
Holdsworth, R. E., Trice, R., Hardman, K., McCaffrey, K. J., Morton, A., Frei, D., Dempsey, E., Bird, A., & Rogers, S. (2020). The nature and age of basement host rocks and fissure fills in the Lancaster field fractured reservoir, West of Shetland.

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.
