Аннотация:Bituminous substances and polycyclic aromatic hydrocarbons in soils under karst rocks have been
studied for revealing fluxes of oil and oil products in karst cavities near the earth’s surface (with the Polaznenskii
Peninsula in Perm region as an example). It has been found that the hydrocarbon fluxes from underground oil
lenses to the surface can be directly detected from the nonspecific organic components of soils and the compo-
sition of free gases circulating in soils. Changes in the soil-geochemical parameters indicative of the presence of
an underground oil lens have been revealed. It has been shown that the hydrocarbon fluxes from underground
oil lenses to the surface can be mapped from nonspecific organic soil components: composition and amount of
bituminous substances, polycyclic aromatic hydrocarbons, and gaseous hydrocarbons.
