Fig. 3

Typical stepwise AF demagnetization results of NRMs for the first-sampled (GSDS1) specimens, individually displayed on the orthogonal vector diagram (Zijderveld 1967), illustrating the HFC (red bar) and LFC1 (blue bar) segments (see text for details), with the associated NRM intensity decay curve. A characteristic (HFC) direction determined by the PCA (Kirschvink 1980) without anchoring the origin is shown. On the Zijderveld diagram, open (closed) dots indicate the end-points of NRM vectors in the vertical (horizontal) plane at each AF level. For details of the respective types of the results, a to f, see text (“Paleomagnetic results” section)
