The results of a study using chromatography-mass spectrometry of Naftalan oil: medicinal (I-II horizon), fuel (III-IV horizon) and used for medicinal purposes during a year in the Naftalan health center in order to determine hydrocarbon and biomarker compositions are presented. Terpanes (191), steranes (m/z 217), hopanes (m/z 191) and adamantanoids (m/z 135, 136, 149, 163) were identified for the first time in Naftalan oil. It was noted that medicinal oil contains approximately 4 times more biomarkers than fuel oil (7.6%; 1.6%, respectively). As a result of a comparative analysis of biomarker indicators of medicinal and fuel Naftalan oil, carried out on a biodegradation scale, it was shown that medicinal Naftalan oil belongs to the biodegraded oil type B-1, stage I-II, with a moderate degree of biodegradation, and fuel Naftalan oil belongs to the chemical type A2, which is typical for oils with a low degree of biodegradation – stage I. Based on the decrease of biomarkers in the composition of Naftalan oil, used throughout the year for treatment, a conclusion was made about their possible participation in the balneological process. Judging by the geochemical parameters, medicinal and fuel oil has the same genesis.
