Figure F1. Orthogonal vector (Zijderveld) plots of demagnetization behavior of representative basalt samples from Leg 17. A. Site 169. B. Site 170. C. Site 171. Points denote projection of magnetization vector endpoint on two planes, one horizontal (oriented north and east; solid symbols) and one vertical (oriented up and north; open symbols). Natural remanent magnetization (NRM) represents the undemagnetized vector. Demagnetization steps are labeled in milliTeslas.
