Dewey & Casey (2013) present a model for generation of the Bay of Islands Complex and its metamorphic sole that is anchored on intra-oceanic subduction initiation at a ridge–transform boundary. Several aspects of this model are inconsistent with a wealth of geological relationships and cannot readily accommodate the geological complexity of associated units in Newfoundland.
