Abstract:

The composition of bottom sediments is considerably derived from the  geochemical characteristics of the subsurface rock. The analysis of 69 bottom sediment samples of 40 water bodies in Nether-Polar and North Urals revealed increased concentration of Pb, Mn, Fe, Cu and Cr in comparison with the average for Western  Siberia. The metals demonstrate significant variability of concentrations up to the multiple exceedences of the Clark values of the lithosphere, which means the contrast lithogeochemical conditions. Critical elements of the bottom sediments are Zn and Ni. Occasionally low concentrations of Cu are observed. Mn, Fe, Cr and Hg are approximately at the Clark lithosphere level. Exceeded concentrations of Pb are found out. Within Tagil structural minerogenic megazone (paleoceanic sector) mean concentrations of Pb, Mn, Fe and Cu are increased and they are decreased to the west (Central Urals structural minerogenic megazone-paleocontinental sector) and to the east (Trans-Ural structural minerogenic megazone-mesozoic-kainozoic plate sector).
