| Summary: | The results of hydrogeochemical studies and groundwater mapping in the Kama PreUrals are given in the article. Analytical data (more than 2000 spectral analyses of water samples, mainly from the springs) are analyzed. Regularities of distribution of the background values of basic geochemical parameters (macro – and microelements) in groundwater has been studied. Hydrogeochemical particularities are revealed. Hydro-geochemical zoning was conducted and the geochemical anomalous zones were deter-mined. Studies provided for the first time an integrated assessment of microelements hydrogeochemistry of the Western Urals and the PreUrals at the regional level. A large number of hydrogeochemical anomalies are located on the territory of the Perm region. It was established that concentration for 18 elements exceeds a legislation admissible limit. The large anomalous zones are characteristic for high concentrations of Br, B, Ba, Mn, and Ti, but anomalies of Sb, Be, Cd, V, Cr, Ni, Pb, Sr, F, Zn, Co, Mo, and P are observed locally. Anomalies in the zone of active water exchange form 14 complex geochemical anomalous zones of areas from 2 000 up to 9 000 km2. The natural environments of formation of hydrogeochemical fields are the main factors of generation of the geochemical anomalies with predominant role of structural, tectonic conditions, and geodynamic (neotectonic) activity. The major hydrogeochemical anomalies spatially coincide with litho-geochemical, geophysical anomalies, and geodynamic active zones. |
