Detachment faulting during continental breakup and slow/ultraslow seafloor spreading Detachment faults, apparently gently-dipping long offset normal faults, are observed in some continental rifts, at some rifted margins, and at both slow and ultraslow spreading ridges. Key questions revolve around their …
A preview of the Bergen Arcs Seismic Experiment (BASE) and how the data collected will be automatically processed In this talk, I will give an overview of the Bergen Arcs Seismic Experiment (BASE), which is currently ongoing and aims to …
Selective influence of pre-existing intra-basement shear zones on subsequent rift-related normal faults Pre-existing intra-basement shear zones can induce mechanical and rheological heterogeneities that may influence rifting and the overall geometry of rift-related normal faults. However, the extent to which physical …
