Thermolysis of Karmal and Ashal'cha native asphalts is conducted at 450 °C. It is shown that in the thermolysis process the content of resins decreases and of oils (hydrocarbons) increases. Chromatomass spectrometry is used to analyze the hydrocarbon composition of the oils. Thermolysis of Karmal native asphalts leads to increased content of both saturated and alkyl- and naphthene-substituted mono-, bi- and tricyclic arenes. Thermolysis of Ashal'cha native asphalt, on the other hand, leads to reduced content of cyclanes, alkyl- and naphthenobenzenes, and naphthene-substituted naphthalenes and phenanthrenes, but increased content of alkanes and alkyl-substituted naphthalenes and phenanthrenes
