“…The relationship between hydrothermal vents and radial faults has never been investigated from seismic data to the best of our knowledge. In parallel, the exact mechanism for such vent-related radial faulting remains unclear and undocumented, as opposed to radial faults found at the crest of salt structures e.g., (Carruthers et al, 2013;Mattos et al, 2016;Stewart, 2006;Withjack and Scheiner, 1982). These are all crucial for an inclusive understanding of the evolution of hydrothermal vent complexes.…”

“…The physical models of Ge et al (1995) showed that reactive diapirs are capable of restricting 530 lateral growth of supra-salt faults and causing a local change in fault strike near the salt-531 sediment interface (Y-shaped splay), where the latter likely reflects near-diapir stress 532 perturbations (see Carruthers et al, 2013). We observe similar salt-fault relationships in the 533 Egersund Basin, with Kimmeridgian faults changing strike by about 90° immediately adjacent 534 to the Omega and Delta diapirs (Fig.…”

“…There is little evidence for a mechanical explanation for this distribution of upper tips because the whole of the Tertiary succession is composed of claystone. It is thus more likely that the upper tier surface defines a palaeo-seabed at which upper tips arrested and ceased vertical propagation (CARTWRIGHT, 2011;BERNDT et al, 2012;CARRUTHERS et al, 2013). We consider this to be likely also for the Lower Congo PF tier and propose that faulting ceased at the end of Pliocene before the phase of fluid flow that formed overlying linear shallow depressions and chimneys.…”

“…The upper tips of PFs typically occur at a specific seismic horizon or horizons within a thin interval of only few 10's metres thick and this is persistent over vast areas (> 100 km 2 ) (cf. examples from the Tertiary North Sea (LONERGAN et al, 1998;CART-WRIGHT et al, 2003;CARRUTHERS et al, 2013). There is little evidence for a mechanical explanation for this distribution of upper tips because the whole of the Tertiary succession is composed of claystone.…”
