Abstract
The Taconian orogeny is generally considered to have resulted from an arc-continent collision. However, geochronological data indicate that much Taconian deformation predates arc magmatism. We propose that the Late Ordovician-Early Silurian tectonic environment in southern Quebec resembled the configuration of the Oman-Iran transect, where subduction took place in the final stage of a large obduction.
