| The general definition of isotopes and stable isotopes. Isotope fractionation and the reason of C isotope fractionation. The stable isotope ratios of organic matters and the use of stable C isotopes compositions to determine depositional environment. The C isotope ratios of petroleum and bitumen from source rocks. The use of C isotope compositions in oil-source rock correlation. The C isotope compositions of different fractions of organic matter (kerogen, oil, asphaltenes, NSO compounds, saturates, bitumen, aromatics) and spesific n-alkane compounds.
