Description:

This is another image showing the accretionary wedge material in blue. The black spots are areas of oceanic crust or partial ophiolite sequences. This material confirms that there was persistent Andean-style Arc subduction along the western edge of NA during early Mesozoic time. Courtesy of Prof. Burchfiel.
