metadata.name: dc.description.abstract
metadata.value: Despite their great importance, Holocene — Late Pleistocene sediments are poorly studied
  in the valleys of rivers in the Krasnoyarsk forest-steppe territory. We present the first detailed
  study of the geochemical composition of the first floodplain terrace sediments in the valley
  of the Berezovka River, and the continuous accumulation that occurred at the Late Pleistocene
  — Holocene (from 20833 ± 519 cal yr BP). This is of great fundamental importance and
  is the basis for further studies on the influence of anthropogenic activities on the natural environment
  in the Krasnoyarsk agglomeration. The sediments were covered by modern alluvial
  dark-humus hydrometamorphosed soil. Macromorphological studies and investigation of the
  humus content have revealed a well-developed process of humus formation and humus accumulation,
  a gley process. The measured contents of some elements (U, Pr, Rb, V, Bi, Cd, As, Th,
  Ga, Co, and Sm) exceeded the respective Clarke values for the Earth’s crust. The distribution
  of most elements and their accumulation in the Middle-Late Holocene (from to 5477–4985
  to 1241–803 cal yr BP) in the middle of the sediment profile is explained by the high content
  of mud and clay minerals. Based on the coefficients of radial migration, we established that
  most of the studied elements were introduced into the sediments during high water levels and
  floods. The values of palaeomarkers indicate a change in climatic conditions in the Late Pleistocene
  and Holocene from dry and cold to more humid and warm, and from arid and cold (in
  the Early Holocene) to modern climatic conditions, respectively.
