The isotopic composition of carbon of the bitumens of the hydrothermal ore fields of the Donets Basin is established. The content of the heavy isotope 13C in the bitumens of the Nikitovka, Druzhkovka-Konstantinovka, and Slavyansk ore fields is determined by the values of δ13C in the internal −18.27 ÷ −27.0 ‰ (PDB standard). This indicates that the predominant source of their formation was the carbonaceous rocks of the middle and upper Carboniferous. A model for the formation of bitumen-hydrothermal associations of ore fields in the region has been constructed, according to which they have a biogenic-abiogenic origin.
