Sediments of specific composition and content of precipitates were found as a consequence of increased concentration of sulphate at the Quaternary groundwater. Precipitates with elemental Al0 and fibres of alloy of Si0, Fe0 and Al0 (max size of Al0 spots cca 300x100 microns) from colloids of Al₂O₃.nH₂O from borewells at Podluží were identified by RTG analyses and SEM in more then 20 analyses. Comparison of chemical composition of Al samples produced by electrolysis at Slovalco Ltd. Co. and of elemental Al0 revealed some parallel in composition and their appearance. Samples ŽIAR1 and ŽIAR3 have similar chemical composition of Al with Al from VIS 15 (as it was a task given to Uhe Slovalco production), but they differ in appearance. The rest of group (samples ŽIAR 2, ŽIAR 4, ŽIAR 5) differs from VIS 15 in composition and appearance of basic Al matter and specific alloys of Al, Si, and Fe.
