“…Three large magmatic areas can be distinguished: Dakar or Cap-Vert, Cayar seamount and Leona. Crustal thinning has been inferred by Liger (1980), Liger and Roussel (1979), van der Linden (1981) and Roussel and Liger (1983). 2 (Meagher et al 1977).…”

“…The age of the sedimentary deposits in the SMB ranges from Triassic to present and sediment thickness averages 1,500m (a few tens of meters towards Bakel to the east and more than 10,000 m along the western Atlantic coast) (Roussel and Liger, 1982;Ritz, 1984;Ritz and Flicotaux, 1985;Rochet and Villeneuve, 1987;Ritz and Bellion, 1989;Rocchi et al, 2007) ( Figure 1). …”

“…The American features can only be understood fully if they are considered along with those of Mauritania (Lefort & Klitgord 1983). The details of the gravity and magnetic data used for this comparison can be found in Roussel & Liger (1983), Klitgord et al (1983) and Lefort (1984). S of Long Island, geophysical markers of the N American and African margins pass into one another.…”

Summary The boundary between Gondwanaland and Laurussia can be traced from Portugal to southern New England using gravity and magnetic data. Further positional control using geochemistry and palaeomagnetism on rocks near the geophysical suture confirms its position. From Long Island to Florida the suture lies beneath the Coastal Plain and our interpretation relies only on geophysical data. This suture is marked by rift-associated rocks, back-arc intrusives, volcanic-arc rocks or remnants of oceanic crust. Onshore, between Cape Ann (near Boston) and Long Island Sound (near New York), the suture possibly follows the Clinton-Newbury fault. The arc-like swing to the W of the Chesapeake Bay region is probably the result of an indentation of the older Appalachian belts by the Mauritanian Reguibat prong during Carboniferous time. There are two major transform faults associated with the suture zone: N of Florida and W of Spain. Two satellite sutures can be identified on the eastern side of the Atlantic. In northeastern Senegal and Mauritania the major gravity high which parallels the Mauritanian orogenic belt is interpreted as locating the Taconic? collision between Gondwanaland and a western microplate. S of Brittany the Spanish microplate collided with Laurussia during Acadian time. These two satellite sutures were rejuvenated during the main late Palaeozoic compression between Gondwanaland and Laurussia.
