Abstract: | Summary A tectonic interpretation of the magnetic anomalies off the coast of California, Oregon and Washington between 40° and 52° north latitude shows that in the area surveyed the oceanic crust is cut by seven major dislocation zones which divide the region in eight areas. For five of these areas the original connection can be reconstructed. The existence of a window of young crust surrounded by older crust and of a short, isolated length of active oceanic ridge southwest of Vancouver Island as proposed recently by different authors is not confirmed. |
