Abstract: | The lithostratigraphic, radiocarbon, macro- and micromorphological, particle-size, and other analyses have been applied to
reconstruct the Holocene evolution of soils and landscapes on the high- and mediumlevel floodplains of the Nepryadva River
in the Kulikovo field area. It is shown that the soils buried within the thickness of alluvial sediments on the high- and
medium-level floodplains were formed in different times and had their own evolution patterns; the polygenetic nature of these
soils is demonstrated. The development of floodplain landscapes in the Holocene was affected by the long-term climatic fluctuations.
The bed of the high floodplain was formed during the Late Valdai glacial stage. The beginning of the development of an intricate
sequence of buried soils and sediments of the floodplain dates back to the Boreal period. This pedosedimentary sequence in
the studied area can be referred to as the Kulikovo sequence. In the course of its formation, the pedogenic stages with a
predominant development of soils alternated with the lithogenic stages of active alluviation and deposition of colluvial deposits
from adjacent slopes on the floodplain. |
