Figure F170. Alternating-field demagnetization (demag) behavior of one of stable samples studied. Dots on the data table and double squares on the intensity plot show the values used for principal component analysis (PCA). High demagnetization fields are required to reduce the intensity, and inclination changes at progressive demagnetization steps are smaller than for other samples. Dec = declination, Inc = inclination. MAD = maximum angular deviation.
