Notes: NRM = natural remanent magnetization, AF = alternating-field demagnetization, TT = thermal demagnetization. Characteristic direction polarity ratings: N or R = well-defined directions computed from at least three vectors, NPP = samples that did not achieve adequate cleaning during demagnetization but their polarity was obvious, R?? = uncertain.
