From: Triassic (Anisian and Rhaetian) palaeomagnetic poles from the Germanic Basin (Winterswijk, the Netherlands)

Fig. 4

Representative examples of orthogonal demagnetization diagrams (Zijderveld 1967) of the Anisian (WW 1–9) and Rhaetian (WW 10) samples from the Winterswijk quarry, both thermally (a, b) and by alternating fields (c-f). Characteristic Remanent Magnetizations (ChRM), called setpoints according to the terminology of McFadden and McElhinny (1988), could be determined occasionally (a, c, e). In the majority of the cases, however, the ChRM could not directly be determined and we calculated the best fitting plane (great circle) through the overprint and the origin (b, d, f)
