- Аннотация: The Cenomanian-Campanian deposits of Tuarkyr (northwestern Turkmenistan) are studied magnetostratigraphically with a reliable paleontological control. Turonian-Campanian rocks possess a high paleomagnetic stability. The existence of a reversed polarity subzone in the middle Cenomanian and several reversals in the Turonian-Coniacian is confirmed. The Santonian-Campanian of the section is dominated by a reversed polarity. The results of the study point to an intricate magnetic zonation of the Cenomanian-Campanian and together with the analysis of data on the Upper Cretaceous of other regions, suggest the necessity of revising the Cenomanian-Campanian interval of the magnetostratigraphic time scale, which has been traditionally considered as an interval of a predominantly normal polarity. New data on the Cenomanian-Campanian geomagnetic field regime also suggest that geodynamic models relating the epoch of the quiet Cretaceous field to various geological events should possibly be reexamined.
