Figure 5.5 Correlation of sections of Kotuy and Norilsk regions (a) and a color
key (b). A black and white version of this
figure will appear in some formats.
For
and excursional intervals we observe several
ows (C20
-
C31) that mark the
rst
arrival of the geomagnetic
normal state, succeeded by a possible
post-transitional excursion (DG8, ID6, DG9(?)). The uppermost three
eldtoa
“
precursor
”
flows (DG9) in
the Sunduk section possibly record the
final arrival of the
eldtoafullynormalstate.
