A Paleocene Paleomagnetic Pole from the Gringo Gulch Volcanics, Santa Cruz County, Arizona

Paleomagnetic data from 25 sites (5 samples per site) in andesite flows of the Gringo Gulch Volcanics in Santa Cruz County, Arizona, were analyzed to determine a lower Paleocene paleomagnetic pole. Alternating-field demagnetization to 500 oe peak field was sufficient to erase secondary viscous components. The mean direction of magnetization (inclination = -58.8°, declination = 167.5 °) was obtained by averaging the site mean directions of the 25 sites, which are all reversed. The resultant lower Paleocene pole position is at lat. 77.0 °N, 1on. 201.0 °E (dp = 1.2 °, dm = 1.7 °).Antevs LibraryThis item is part of the Geosciences Theses collection.
