Implications of Mesozoic—Recent basin development in the western Inner Moray Firth, UK

Giant submarine landslide triggered by Paleocene mantle plume activity in the North Atlantic

“…1) (cf. Underhill, 1991;Cooper et al 2012). The Halibut Slide headwall region is located adjacent to these faults, lying ~50 km east of the Great Glen Fault Zone and 100 km north of the Highland Boundary Fault Zone (Figs.…”

“…The Moray Firth paleo-shelf is estimated to have undergone up to 390 m of uplift during the Paleocene (Nadin and Kusznir, 1996). Early Cenozoic fault reactivation within the Moray Firth has also been linked to North Atlantic tectonism (e.g., Underhill, 1991). Aeromagnetic data showing offset dike swarms across the WSW-ENE-trending fault zones that crosscut Northern Ireland and Scotland, combined with dating of igneous centers and dike swarms in Northern Ireland, showed that these crustalscale strike-slip faults were active in the early Paleocene between 64 and 62 Ma (Cooper et al 2012).…”

Geometrically coherent continuous deformation in the volume surrounding a seismically imaged normal fault-array

“…between mapped horizon cut-offs (Needham et al, 1996). Throw was measured 175 along sample lines orientated perpendicular to the average strike of the studieddisplacements (Underhill, 1991b) and the location of the sample grid was fixed, 178 allowing comparison of displacements on different horizons. A disadvantage of 179 using a fixed, oriented sample gird arises when individual faults are not parallel to 180 the average fault strike for the sample volume.…”

Microstructures in the Cretaceous Bima Sandstone, Upper Benue Trough, N.E. Nigeria: Implication for hydrocarbon migration

“…Geological studies of extensional sedimentary basins that have experienced subsequent compression demonstrate that these tectonic processes exerted a fundamental control on trap formation and integrity, seal breach, and timing of hydrocarbon maturation (Underhill, 1991).…”
