Složení sedimentů, Al-Si gelů a precipitátů vázaných na výskyt elementálního Al, Si, Fe z monitorovacích vrtů u jímacího území Podluží
Ďurďová, Libuše
Occurrence of increased sulphate concentration in groundwater of the Quaternary sediments in the floodplane of the Morava river watershed is related to many specific features in hydrogeology, hydrochemistry, microbiology, geochemistry, exploitation of water resources, climatic conditions, and technical equipment of boreholes. One of the concsequences is genesis of 2-4 m thick layer of sediments at the bottom of moitoring boreholes Vis with mineral precipitates, sludge, Al and Si gelatines, precipitates of elemental forms of Al, Si and Fe. There were found also colloids of FeS2 composition and minerals goethite, magnetite, lepidocrocite, pyrite, greygite under extreme oxido-redox conditions.
