“…On land, numerous studies show that the deformation occurred in France, Great Britain, and Germany, and was created by compression along a 10-20°N direction (de Charpal et al, 1974;Bergerat and Geyssant, 1980;Letouzey and Trémolières, 1980). Following the orientations of pre-existing structures, this compression phase created strike-slip faults, reverse faults, folds, and uplifts.…”

A new bathymetric map, based mainly on Seabeam data, has been established for the Goban Spur area during a postcruise survey of DSDP Leg 80. Using both Seabeam data and a new series of eight seismic profiles obtained perpendicular to the continental margin, we have constructed a new detailed structural map of the Goban Spur continental margin which clearly reveals Caledonian and Variscan trends. Both the thinning of the Goban Spur continental crust, from Early Cretaceous (late Cimmerian phase) to middle Albian time, and subsequent widening of the adjacent oceanic domain, from middle Albian to Campanian time, resulted from tensional movements in a N70° direction which followed Caledonian trends. During the rifting phase, the tops of the tilted fault blocks remained close to sea level. The rapid subsidence of the margin seems to have occurred in the early Albian during the last stage of rifting.Eocene intraplate deformation affected the whole Goban Spur continental margin, but is particularly evident at the Pastouret Ridge, a reactivated oceanic fracture zone. The oceanic domain underwent a slight intraplate compression, which fractured the old oceanic crust through its entire thickness, probably along previous zones of weakness, such as fracture zones.

“…Numerous studies show that deformation occurred on land in the whole continental domain of North Africa, Iberia, and Europe (de Charpal et al, 1974;Letouzey and Tremolieres, 1980;Bergerat, 1985). The stress field is characterized by a northsouth horizontal compression, in agreement with the relative north-south compressive motion of Africa with respect to Eu rope (Savostin et al, 1986), which resulted in a transcurrent tec tonic regime from northeastern Iberia to the Rhine graben and the Bohemian Massif.…”

A new bathymetric map, based on Sea Beam data, was compiled for the continental margin south of Galicia Bank, in the area of Ocean Drilling Program (ODP) Leg 103 drilling. Using a new series of 12 single-channel seismic profiles oriented perpendicularly to the continental margin and multichannel seismic profiles previously acquired in the area, we constructed a detailed map of the surface of the tilted fault blocks and half grabens formed during the Early Cretaceous phases of rifting. Tilted fault blocks 13-18 km apart and oriented roughly north-south, are continuous over distances of as great as 60 km. We divided the upper and lower parts of the margin on the basis of magnetic data, distance be tween tilted fault blocks, nature of sediments involved in the rifting processes (pre-and syn-rift or only syn-rift sedi ments). This report also discusses the significance of the S reflector located below the tilted fault blocks.

“…It runs subparallel to the eastern margin of Mediterranean Sea (Neev et al, 1982). Indeed, according to the microtectonic analysis (Eyal and Reches, 1983;Letouzey and Tremolieres, 1980), they resulted from E-W to WNW-ESE horizontal compression, where this was generally NNW-SSE directed in the Western Desert, shifting progressively to NW in Sinai and nearly E-W in neighbouring regions to the east (Sehim, 1993). This eastward increase in the shortening along the Tethyan margins (Guiraud and Bosworth, 1997) is synchronous with counterclockwise rotational northward drift of the African-Arabian plate and its increased collisional coupling with the Eurasian plate (Le Ziegler, 1990).…”
