The North American Cordillera has experienced a dramatic history of tectonic and paleogeographic evolution over the past 400 million years and is the birthplace of the accreted, or “suspect,” terrane concept. Much of the western part of the Cordillera is composed of crustal fragments which have been shuffled along the continental margin, or across vast oceanic basins, or both, and subsequently juxtaposed along their common fault boundaries. Interpreting this evolving and complex orogenic collage relies on a variety of geological, paleontological, and geophysical evidence. Although the evidence is seemingly abundant, disagreement exists in its interpretation, and different data sets provide conflicting results.
