Abstract

Combining paleomagnetic data for 17 new sites from the northwest portion of the (Oligocene) San Juan volcanic field of southern Colorado with data for 29 sites previously published yields a paleomagnetic pole at 85??N, 114??E (with a 95% confidence circle of 7.5?? radius). A further combination of the San Juan data with the results of other studies on rocks of Oligocene age from tectonically stable parts of North America gives a mid-Tertiary reference pole located at 81??N, 132.5??E, with a confidence circle of approximately 4??. Mid-Tertiary paleomagnetic poles for the western edge of the continent diverge markedly from this reference pole. ?? 1977.
