Abstract:
Purpose. The aim of the present study was to determine paleogeographic and paleogeodynamic features of sedimentogenesis of sandstone-siltstone associations of upper Paleoproterozoic of Kryvoy Rog iron ore basin based on lithochemical data. The main tasks were to investigate the lithochemical structure of the geological data, reconstruct the source mineral composition of metasedimentary rock, and compare the results with non-metamorphosed analogs.
Methodology. Multivariate statistic methods for clustering the data were employed, including the principle of serial comparison with non-metamorphosed analogs by a number of lithochemical coefficients and diagrams.
Findings. Metasedimentary formations of Gleevatsky suite of Kryvoy Rog iron ore basin were attributed to poorly differentiated subgreywacke and greywacke sandstone-siltstone rock association, which is characterized by intermediate petrochemical parameters between humid and arid terrigenous Phanerozoic series. Sedimentation was formed due to erosion of protolytes of plagiogranitoids of Archean base and earlier sediments of Paleoproterozoic cover. Tectonically active semiarid basin conditions of sedimentation are thought to be present.
Originality. The set of elementary lithochemical clusters characterizing granulometric and chemical spectrum of metasediments of Gleevatsky suite was determined. Lithochemical types of upper Paleoproterozoic of Kryvoy Rog iron ore basin were specified.
Practical value. Research contribute to improving lithochemical systematic of metasedimental rocks of Krivoy Rog iron ore basin. The determined lithochemical features of the rocks can be an important criterion for the correlation of stratified Early Precambrian complexes of Ukraine and other shields.
