Paleomagnetic orientation of core from drill hole USW GU-3 Yucca Mountain, Nevada: Tiva Canyon Member of the Paintbrush Tuff
Orientations for 83 core segments of the Tiva Canyon Member of the Paintbrush Tuff from drill hole USW GU-3 at Yucca Mountain, Nevada, were determined by comparing the remanent directions from the core segments to a paleomagnetic reference direction. The mean direction of remanence for the Tiva Canyon Member (D = 167.8, I = -41.5) from 9 surface localities at Yucca Mountain was taken as the reference direction. The core segments sampled include 16 which were acquired with an orienting barrel. For one run the orientation data (provided by American Coldset) were found to be in error by 180{sup 0}. Other discrepancies between the paleomagnetic orientations and the American Coldset data are attributed to errors in matching depths from the orientation logs to corresponding positions on the core.
