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...

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.
