Paleomagnetic data were obtained from nine cooling units of the Late Cretaceous (∼72 Ma) Roskruge Volcanics and from 25 flows in the lower Paleocene Gringo Gulch Volcanics, both from southeastern Arizona. Alternating field demagnetization successfully erased the infrequent secondary components of ma...
