The article considers the conodont characteristic of the one of ore-containing volcanogenic — sedimentary formation of the Magnitogorsk area of the East-Magnitogorsk Zone — the Gora Magnitnaya Formation. The Formation, was established during the geological mapping in the late 80s. Conodont complexes have been established in the formation, which are well compared with most of the standard conodont zones and horizons of the Famennian stage of the Upper Devonian and the Tournaisian stage of the Lower Carboniferous. Conodont zones have been identified in the Famennian stage: Pa. marginifera, Pa. postera, Pa. expansa S. praesulcata corresponding to the tops of the Makarovsky, Murzakaevsky, Kushelginsky and Lytvinsky Horizons; in the Tournaisian stage there are zones: S. sulcata, S. duplicata, S. belkai, S. quadruplicate, S. isosticha, corresponding to Malevsky, Upinsky, Kosorechensky, Kizelovsky Horizons the West Ural sub-region of the stratigraphic scheme of the Urals. For the first time in this area were carried out a stratigraphic dissection of the conodonts fauna of the boundary Devonian-Сarboniferous deposits and the determination of the Humerian horizon.
