- Аннотация: The magnetostratigraphic study of the geomagnetic reversal frequency just before the Ordovician Moyero superchron can be very useful for testing various geodynamic conceptions and different geodynamo models describing the geomagnetic field evolution. In terms of completeness of the geological record, the Ordovician carbonate-terrigenous key section of the Moyero River valley, located in the northern part of the Siberian Platform, is considered to be one of the best Ordovician sections of Northern Eurasia and seems to be very promising to carry out such a study. However, the Tremadocian part of the section, which could record the presuperchron reversal history, until now remained poorly studied and exact positions of its boundaries with underlying Upper Cambrian and overlying Arenigian (Floian) strata are still not well determined. In this study we present magnetostratigraphic data, which taken together with obtained biostratigraphic data, allow constraining the position of the Tremadocian–Arenigian (Floian) boundarywithin the keyMoyero River section.
