Figure 6

Graphical representation of the virtual geomagnetic pole (VGP) latitude against stratigraphic height, and the resultant local magnetostratigraphy. (MAD: maximum angular deviation, Inc/Dec: inclination and declination of each ChRM direction). Four magnetozones with normal polarity, named N1, N2, N3 and N4 and three magnetozones with reversed polarity named R1, R2 have been defined. At least two magnetostratigraphically consecutive sites of the same polarity were required to define a change in polarity, otherwise a grey bar represents a single site.
