a Flows in each section are sorted from the bottom (
(first row) to the top (last row) of
stratigraphic sequence. DG
¼
directional group, ID
¼
individual direction (see text);
nn
¼
sequence; DG (ID)
¼
name of DG or ID correspondingly; N DG ¼
number of
ows
within the DG; N ID ¼
number of samples within the ID; D / I
¼
declination/inclination in
parameters of Fisher statistics.
b DG and ID mean paleomagnetic direction for the Kotuy composite section, calculated
without anomalous ID3, ID4, ID5 and DG17 (see discussion in Pavlov et al ., 2011 ).
Corresponding paleomagnetic pole is: S lat ¼
geographic coordinates; K and

¼

¼
( S lat , S long ¼
latitude and longitude of the mean sampling
point; P lat , P long ¼
latitude and longitude of the paleomagnetic pole; dp/dm
¼
semi-axes
of the ellipse of con
dence about this paleomagnetic pole.)
