Creator:: Schultz, Karin L.
Abstract:: An understanding of the tectonic history of the Klamath Mountains is crucial for a valid paleogeographic reconstruction of the Pacific Northwest. However, prior to this study there were very few paleomagnetic (PM) data from the Klamath Mountains (KN), which resulted in conflicting interpretations about the role of the KM province...
