Summary: | The part of the north Atlantic where Iceland is currently forming has functioned as a tectonic divide since the opening of the ocean, and has persistently featured paired spreading ridges and intervening microplates. At the time of ocean opening a ~ 100-km long, right-stepping transform fault, the Faeroe transform fault (FTF), formed where the new spreading ridge crossed the Caledonian suture [Bott, 1985] (Figure 1a). Tectonic complexities subsequently rafted several continental blocks into the ocean, including Jan Mayen, the Jan Mayen microcontinent (JMM) and the Faeroe block. |
