Figure 5. Representative vector end-point diagrams showing the results of thermal and alternating field demagnetization for samples from the "fresher" lower part of the peridotite section in Holes 897D and 899B. Reversed polarity of magnetization is revealed in all samples. A. Sample 149-897D-16R-3,42-44 cm. B. Sample 149-897D-16R-3, 30-32 cm. C. Sample 149-899B-23R-1, 12-14 cm. D. Sample 149-897D-16R-2, 72-74 cm. Plus signs and circles represent the projection of the magnetization vector end-point on the horizontal and vertical planes, respectively. NRM = natural remanent magnetization. Note that Samples 149-897D-16R-3. 42-44 cm, (A) and 149-897D-16R-3, 30-32 cm, (B) were taken from same piece of continuous core section.
