Webb19 okt. 2024 · These two mid-ocean ridges imply an additional tectonic plate between the Kula and Farallon plates offshore western North America during early Cenozoic time (purple shaded region of Fig. 5). Previous studies have proposed vanished plates along the NW Cordillera in early Cenozoic time (Haeussler et al., 2003; Madsen et al., 2006). Webbthe two models. Note the similarity of the two models, especially those of the Farallon remnants (high seismic velocity anomalies). We use GPlates reconstructions of global plate motions at 1 Ma intervals, in which the plate margins continuously evolve with self-consistent velocities between plates and plate margins [Gurnis et al., 2010].
