Figure F20. Plots of representative alternating field (AF) demagnetization results for discrete paleomagnetism samples, Site U1403. Upper plots show intensity variation with progressive demagnetization, and lower plots show vector endpoints of paleomagnetism directions on orthogonal vector diagrams (i.e., Zijderveld plots). Vector diagrams indicate that samples in A and B record well-resolved characteristic remanent magnetization (ChRM) directions, whereas the sample in C does not. Solid circles = horizontal projections, open circles = vertical projections, gray circles = data not used to calculate ChRM direction, black dashed line = ChRM direction. Inc = inclination, Dec = declination, MAD = maximum angle of deviation.
