metadata.name: dc.description.abstract
metadata.value: The work presents the results of a comprehensive mineralogical and geochemical study of
  Late Pleistocene-Holocene bottom sediments of Lake Onego and small lakes located in the
  territory belonging to Onego Ice Lake. Methods of ICP-MS, atomic absorption spectrometry,
  X-ray fluorescence analysis, X-ray phase method (XRD), scanning electron microscopy
  (SEM), and gamma-spectrometric method were used. The geochemical composition of the
  terrigenous fraction reflects the mineral composition and is permanent for the all bottom
  sediments cores of Lake Onego and small lakes during time interval about 12.000 years. For
  the first time, detailed mineralogical studies of sediments have shown that the composition
  of mineral associations of the terrigenous fraction is similar in the bottom sediment cores of
  Lake Onego and small lakes. The association of authigenic minerals in bottom sediments is
  distinguished by the presence of pyrite framboids in small lakes, and crystalline aggregates of
  Fe-phosphate, ferruginous illites and chlorites in Lake Onego. Sedimentation rates established
  by the study of correlations the indicator technogenic radioisotope 137Cs and atmospheric
  210Pb. In the bottom sediments of small lakes, sedimentation rates vary from lake to lake, as
  well as in various areas of Lake Onego in the range from 0.05 cm/year to 0.30 cm/year.
