Figure F26. A–E. Representative examples of alternating field demagnetization of archive-half core pieces, Hole U1415I. Note that with the exception of Sample 345-U1415I-2R-1A, 52 cm, which shows a single well-defined remanence component, all samples are affected by acquisition of a spurious anhysteretic remanent magnetization (ARM; red arrows) at higher demagnetizing fields. Right plots are details from circled areas in the left plots. Solid circles = projection onto the horizontal plane, open circles = projection onto the vertical x–z plane. NRM = natural remanent magnetization.
