| The late Tournaisian Event in the successions of the Kosyu-Rogovaya Depression and adjacent areas (Timan-Pechora Province) | |
| The late Tournaisian Event (Mid-Aikuanian Event) appearing as significant changes in marine and terrestrial biota is considered as consequence of the beginning of the Early Carboniferous phase of the Gondwana glaciation and transition from the greenhouse climate to icehouse climate. The event caused one of the highest Palaeozoic shift in the carbon isotope ratio. This shift was traced in the sections of the Kosyu-Rogovaya Depression and adjacent areas: 1-Kochmes borehole, the Izyayu River section, and the Kozhym River section. The isotope shift is dated by conodonts of the Siphonodella isosticha and Gnathodus typicus zones, foraminifers Eoforschia gigantea and Dainella, and algae Exvotarisella. The traces of the late Tournaisian Event are considered as reliable stratigraphic tool for the eastern part of the Timan-Pechora Province.
Keywords: Lower Carboniferous, Tournaisian, isotopic anomaly, late Tournaisian Event, Timan-Pechora Province, Kosyu-Rogovaya Depression. |
