N.I. Коndrashova, P.V. Меdvedev. Geochemical markers as a supporting tool for paleogeographic reconstructions in the Paleoproterozoic (case study of stromatolitic dolostones from the Onego paleobasin) // Transactions of Karelian Research Centre of Russian Academy of Science. No 2. Precambrian Geology Series. 2020. Pp. 66-83

Keywords: Onego paleobasin; Paleoproterozoic; Jatulian group; stromatolitic dolostone; geochemical marker; paleogeographic conditions of sedimentation

The article studies the values of different geochemical indicator ratios (V/ (V+Ni), U/Th, Ni/Co, V/Cr) and the content of trace elements in stromatolite dolostones from the Onego paleobasin (Karelia). The results of their analysis were compared against available geological data, and conclusions were made about the applicability of one or another geochemical indicator. It was also assessed whether the data obtained from the analysis of geochemical features of the stromatolite dolostones corresponded with facies criteria used in geological and lithological studies.
