DISTRIBUTION OF GEOCHEMICAL ELEMENTS ON THE DRY BOTTOM OF THE ARAL SEA
Downloads
In the article, as a result of the evaporation of groundwater in the soil-ground layers of the Aral Sea, in salt marshes, salt lakes, saline soils, etc., evaporative geochemical barriers are formed containing Ca, Na, K, Mg, F, S, Sr, migrating substances accumulate, such as Rb, Zn, Li, N, U and Mo. The distribution and concentration of bio microelements in landscape blocks are important indicators. In the soils of the study area, it was found that the substances Sr, Ce and La from the geochemical elements of the earth are predominantly collected in barriers and this is related to the mechanical composition of the soil.
