The Archean gneiss complex of West Greenland contains packages of unrelated rocks created during relatively short periods of time in arc-like magmatic environments, and having similarities to rocks formed at Phanerozoic convergent plate boundaries.

Having summarized the origin of West Greenland Archean crust in arc-like environments, this paper then focuses on new...[Show more]
