Break-up and seafloor spreading domains in the NE Atlantic

Figures showing the long wavelength of the NAG–TEC magnetic anomaly grid, detailed magnetic anomalies and isochrons. Fig. S2 continued. Magnetic anomaly picks (grey circles) used to construct isochrons (thin, black lines); see also Fig. 3. For isochron labels see Table 1. Background image shows the oceanic lithosphere age (see also Fig. 4). Plate boundaries are shown as thick, white lines.
