Correlating deformation events onshore and offshore in superimposed rift basins: The Lossiemouth Fault Zone, Inner Moray Firth Basin, Scotland

The separation and characterisation of different deformation events in superimposed basins can be challenging due to the effects overprinting and/or fault reactivation, combined with a lack detailed geological or geophysical data.
