Two of these units, the Groswater Bay and Lake Melville Terranes are interpreted to represent parts of the parautochthonous and allochthonous units, respectively, which are two regional subdivisions.
This first‐order zonation implies a tectonic polarity to the Grenville Province, superimposed on which are second‐order features evident from contrasting tectonic styles and radiometric ages.
These characteristics are consistent with a diachronous or oblique collisional model for the Grenville by: The Labradorian orogeny in the Grenville Province, eastern Labrador, Canada Article in Canadian Journal of Earth Sciences 29(9) February with Reads How we measure 'reads'.
