Résumé:

The Neoproterozoic Katav Formation, participating in the composition of the Urals stratotype top section, includes a magnetostratigraphic record that can be the source of unique information on geomagnetic field behavior 800-900 Ma ago. For many years, it has been considered that the characteristic magnetization of this formation is metachronous and was formed in the course of the Late Paleozoic diastrophism. New data, obtained during the performed studies, indicate that the characteristic magnetization of the formation is primary, and the formation itself is an ideal recorder of the Neoproterozoic geomagnetic field.
