“The geology of the Bay of Islands in western Newfoundland figured prominently in the development of actualistic, plate-tectonic interpretations of orogenesis, and has been a classic area of Appalachian geology since the pioneering work of R.K. Stevens (e.g., Stevens, 1965, 1970), H. Williams (e.g., Williams, 1971) and J.F. Dewey and coworkers (e.g., Dewey, 1974). Igneous and metamorphic rocks of the Bay of Islands ophiolite were amongst the first to be identified as fragments of ancient oceanic crust (Dewey and Bird, 1971). Sedimentary rocks in the Humber Arm Allochthon represent a combination of passive continental margin and foredeep environments (e.g., Williams and Stevens, 1974), preserving a record of rifting, continental margin subsidence, and continent-arc collision.”¹  Read more….
