| Description |
The main features of the Givetian-Frasnian shoal deposits of the Sub-Polar Urals (Matyashor formation) are considered. The study part of the section corresponds to varcus - rhenana zones on the basis of conodonts. The unconformity corresponding to the upper part of the varcus zone as well as hermanni-cristatus and disparilis zones is detected, the following transgressive sequence is supposed as a sign of the Frasne (Manticoceras) Global Event. Analysis of the sequence allows us to suppose that environment changes in the Matyashor time were controlled by eustatic oscillation of the sea level.
