Features of the Mineralogical Composition of Coarse

The study of the mineralogical composition of sand (0.25–0.10 mm) and coarse silt (0.10–0.05 mm) fractions revealed a significant lithological heterogeneity of soil-forming material in the area of the Zvenigorod Biostation. The domination of ore minerals in heavy fractions (to 42% of grains) and, to a smaller rate, of hornblende and biotite, explains iron accumulation in soil profiles and
