Figure F7. Representative vector end point diagrams (Zijderveld, 1967) showing the results of (A) alternating-field and (B) thermal demagnetization for sedimentary rock samples from Expedition 316 drill sites with well-defined reversed and normal polarity ChRM magnetization. Samples 316-C0004C-1H-1, 37–37 cm, 316-C0007D-11R-1, 3–5 cm, and 316-C0004D-54R-1, 16–18 cm, are normally magnetized; Samples 316-C0008A-25H-1, 95–97 cm, 316-C0006E-20X-6, 27–29 cm, 316-C0008A-34X-1, 49–51 cm, and 316-C0006E-39X-7, 8–10 cm, are reversely magnetized. NRM = natural remanent magnetization. Straight lines in A indicate ChRM component using principal component analysis (Kirschvink, 1980). Black and open squares in B indicate projection of the magnetization vector end-point on the horizontal and vertical planes, respectively.
