Two additional pairs of readings with normal polarity occur at -37 and -40m, and there is another single reading of normal polarity at -44.
The two episodes of normal polarity within a long palaeomagnetic record dominated by reversed polarity can be interpreted as representing the Jaramillo (at -27 to -28.
The results exhibited in Figure 4 are sufficiently accurate to show that no normal polarity magnetization is present in this subset of samples.
We convert our reversed polarity inclination to normal polarity for comparison with the reference by changing the sign from negative to positive.
Another zone of normal polarity occurs in the base of the Ochre Cove Formation, and is correlated to the Jaramillo Subchron (0.
1), all members of the Woorinen Formation are of normal polarity and are, therefore, placed in the Brunhes Normal Chron.
Geophysicists describe today's field as having normal polarity
, while the opposite orientation has a reversed polarity,
For example, 240U120D refers to a 240U-series, standard-recovery, normal polarity
(cathode-to-stud), 1200V, diffused diode, while a 240UR120D refers to the same device with reverse polarity.
Another is that the reversed polarity at the base of the TD section is not part of the Matuyama, but one of the brief episodes of reversed polarity that occurred within the last 780,000 years of the Brunhes period of normal polarity (Champion et al.
Venta Micena is claimed to lie slightly above the Olduvai Subchron of normal polarity (1.
