Back-arc spreading systems; geological, biological, chemical, and physical interactions. The Penobscot collisional event was followed by Arenig-Caradoc subduction under the composite Gander margin, leading to back-arc spreading and formation of the Exploits back-arc basin (see van Staal 1994). Most back-arc basins result from lithospheric extension, possibly followed by back-arc spreading, which seems counter-intuitive considering the overall convergent tectonic framework in which they develop. |
