Pole calculated as a Fisher mean of the 10 intrusion site VGPs in geographic coordinates (intrusive bodies, no tilt correction applied). Baked-contact rows (B63, B64, B29) are included in the sites table to document the positive baked contact tests at sites 63, 64, and 29 (Irving 1972 'Age of Magnetization') but are not counted as independent VGPs in the Fisher mean, since each records the same field as its parent intrusion. Magnetization age 1267 � 2 Ma from U�Pb baddeleyite (LeCheminant & Heaman 1989). Site names follow Irving et al. (1972) site IDs where S = sill, D = diabase dike, B = baked contact, L = lopolith. The numeric ID matches Irving et al. 1972 Table 2."
