“…The asymmetry in the crustal structure of the conjugate margins, as well as a complicated tectonic interplay of magmatism and geological features, like lineaments and/or metamorphic rocks (eclogites) inherited from the Caledonides, suggests a complex rifting evolution and postrift events (Voss and Jokat, 2007;Mjelde et al, 2003). The timing of South Atlantic opening was diachronous, progressing from south to north (Austin and Uchupi, 1982;Blaich et al, 2011;Franke, 2013;Franke et al, 2007;Jackson et al, 2000;Rabinowitz and LaBrecque, 1979;Sibuet et al, 1984;Koopmann et al, 2014a). The use of seafloor magnetic anomalies to date this process is complicated by uncertainties in anomaly picks for the southern margins.…”
