Notes: NRM = natural remanent magnetization, AF = alternating-field demagnetization, TT = thermal demagnetization. Characteristic direction polarity ratings: N = well-defined directions computed from at least three vectors, NP or RP = less precise directions computed from only two vectors or a suite of vectors displaying high dispersion, RPP = samples that did not achieve adequate cleaning during demagnetization but their polarity was obvious.
