Zadonic reefs of the central and southern parts of the Timan-Pechora province and oil-gas presence prospects

The suggested conception of the zadonic reefs formation deviates from the common formation model developed by M.M. Grachevsky and his followers. The reefs observed belong to the near-slope graben-shaped paleobendings. Fractures mostly affected their formation. The zadonic reefs are oil bearing in some fields and perspective for searching of new hydrocarbon accumulations.
