“…In other cases, second-phase rift faults show a constant strike orientation, and are not affected by pre-existing underlying structures. The new faults would then be good indications of the extension direction associated with their formation, for example as argued by Deng et al (2017) for NW-SE oriented second-phase rift faults in another part of the Horda Platform. In summary, to recognize the influence of the reactivation of a pre-existing structure on a fault network, fault strike, density, dip and displacement should all be considered.…”

“…Within the northern North Sea, we observe an overall localization of the rift system from RP1 to RP2, suggesting that there may not have been sufficient time between rift phases to sufficiently strengthen the lithosphere, or that extension was more protracted throughout RP1 and RP2. Observations from the East Shetland Basin and Oseberg Fault Block indicate that fault activity may continue, albeit at a reduced rate, in the interrift period between RP1 and RP2 (Claringbould et al, ; Deng, Fossen, et al, ). However, strengthening of the lithosphere beneath the RP1 axis in the Stord Basin may also have contributed to the lack of activity in this area during RP2 and the localization of activity in the adjacent South Viking Graben (Figure ).…”

“…Structural measurements were converted from the time to the depth domains using the velocity model of Fazlikhani et al (), with those at deeper levels of the basin converted using interval velocities from Christiansson et al (). Although parts of these surveys have been interpreted in local studies (e.g., Claringbould et al, ; Deng, Fossen, et al, ; Duffy et al, ), this represents one of the first studies to integrate the available data with observations from these local studies to resolve the regional multiphase rift evolution of the whole of the northern North Sea.…”
