Biomarkers, due to their specific structure and biochemical functions, under certain environmental conditions are resistant to degradation and mineralization in soils and therefore serve as molecular traces of paleobiota and terrestrial vegetation, as well as the intensity of biochemical processes occurring in the biosphere not only in the present, but also in the past. The group composition of humus, optical densities in the visible and ultraviolet parts of the spectrum, chlorophyll, lipids, fatty acid spectrum, lignin phenols in combination age of soils are recommended as promising methods for paleoecological studies.
