Lithospheric stretching, detached normal faulting and footwall uplift

Abstract: Summary Lithospheric stretching can successfully account for the overall evolution of many sedimentary basins, and detached normal faulting the detailed geometry of the upper crust. In an instantaneously stretched, isostatically compensated basin, the equations which describe these two processes can be combined to define a ‘notional depth to decollement’. Only at this level can the sole to the normal fault system maintain a constant depth below sea-level during extension. The notional de… Show more

“…formation (McGeary & Warner 1986;Jackson 1987;Kusznir et al 1991) and can progressively rotate during extension according to the domino fault model (Ransome et al 1910;Le Pichon & Sibuet 1981;Wernicke & Burchfiel 1982;Barr 1987). Finite element and analogue models for extension support formation of steeply dipping upper crustal normal faults, which are remarkably planar in origin (Vendeville et al 1987;McClay & Ellis 1987;Cundall 1990).…”

“…The hanging-wall is assumed to deform by antithetic fault slip. The uplift of the footwall and hence the amount of erosion, has been calculated using the subsidence modcl of McKcnzic (1978) and Barr (1987), where subsidence = 3.4 (1 -1/B) where B is the stretching factor. An average scdiment density is assumed; sediment is shown stippled.…”

“…However, attempts to calculate footwall uplift rates and therefore determine the elevation of the horsts, using traditional methods (e.g. Barr, 1987;Yielding, 1990;Roberts et al, 1993) are severely hampered by the complex structural setting of the Josephine Ridge, which has seen post-Jurassic subsidence, Paleogene inversion and local salt movement (Fig. 2).…”

“…Isolated Upper Jurassic islands have been reported close to the western margin of the Central Graben (Howell et al, 1996), but the only examples in distal areas of the North Sea are from the Viking Graben, where exposure was implied from reworking of footwall strata (e.g. Barr, 1987;Badley et al, 1988;Yielding, 1990;Roberts et al, 1993;Ravnås and Steel, 1998;Berger and Roberts, 1999;Nøttvedt et al, 2000).…”
