The soil cover of foothills in eastern Georgia preserves the remains o
f bisequal paleocatenas composed of red-earth smectitic clayey soil in
the upper part and black Vertisol (vertic chernozem, smolnitsa) in th
e lower part. Microbiomorph analysis of the Vertisol proved that the s
oil mass originated from the organic matter accumulated in ancient swa
mps and mixed with clayey smectite-containing colluvium in conditions
of swampy forest humid paleoenvironment. The position of this soil in
paleocatena is indicative of the presence and elevation of the zone wi
th red-earth soils and weathering crusts and of the intensity of denud
ation within the local catchment basin.
