COMPARATIVE HYDROCHEMISTRY OF VOLGA-URAL REGION AND WEST-SIBERIAN MEGA-BASIN
Comparing underground and sedimention water content with the history - and pre-history - features, over a number of sedimentation basins, permits to reveal the main factors, controlling the mineralization at each basin. The method is presented by example of Volga-Ural Region and West Siberian Mega-Basin.
