Abstract	The carbon isotope composition of individual n-alkanes in samples of crude oil from the Late Devonian play of the Timan—Pechora basin and rock bitumen that reached the main stage of oil generation has been studied. The carbon isotope composition of individual alkanes of thermal bitumen obtained by autoclaving low-maturity Domanik rocks has been also determined. The carbon isotope composition of individual alkanes of the rock bitumen has been shown to correspond to that of the oil samples, a feature that indicates the syngenetic nature of deposits of these Late Devonian oils. The correlation between the oil and bitumen compositions is also confirmed by matching the composition of acyclic hydrocarbons and polycyclic biomarkers of the test oils and bitumens. For the Domanik organic matter, the carbon isotope composition of n-alkanes has been revealed to depend on the temperature of artificial maturation of the rock organic matter, a finding that potentially increases the reliability of the correlation between the oil and source rock organic matter by the isotope data.
