| Early Carboniferous conodonts from the Vorgashor Formation on the Haruta River (Polar Urals) and interfacial correlation of the upper part of the Lower Carboniferous | |
| This paper presents a study of conodont assemblages from the Vorgashor Formation exposed along the Haruta River (Polar Urals). The material includes subautochthonous conodont associations recovered from hemipelagic deposits and calciturbidites in the lower part of the formation. The taxonomic composition, represented by Gnathodus bilineatus, G. remus, G. praebilineatus, Lochriea commutata, Pseudognathodus homopunctatus, Kladognathus, and Idioprioniodus, indicates a late Viséan-Serpukhovian age. Paleoecological analysis suggests that most taxa were epipelagic and not restricted to particular depositional depths. The obtained data allow for interfacial correlation between sections from different facies belts and refine the applicability of standard conodont zonation within the Upper Viséan-Serpukhovian interval. The first appearance levels of Gnathodus bilineatus and G. bollandensis are proposed as reliable interfacial correlation markers corresponding approximately to the bases of the upper Viséan and upper Serpukhovian substages, respectively. Keywords: conodonts, Vorgashor Formation, Viséan, Serpukhovian, paleoecological analysis, stratigraphy, interfacial correlation, Polar Urals. |
