Figure F4. Orthogonal vector plots for representative basalt samples from Site 597. A. Hole 597B. B. Hole 597C. 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.
