Abstract
The paper presents data from the landscape-geochemical studies in the Upper Angara region. The chemical properties of soils and waters of small rivers on the right bank of the Angara River have been studied. Differences in the characteristics of soils formed in two districts of the Pribaikalskaya province and one district of the Irkutsk-Cheremkhovskaya province have been established. The general hydrochemical analysis showed fundamental differences between the surface waters of two natural structures forming the right-bank part of the basin of the upper section of the Angara River, namely: the Baikal rift zone and the southern part of the Siberian platform. The data obtained confirmed and supplemented the conclusions made 20 years ago about the landscape-geochemical characteristics of the territory.
