| Реферат: | eng: The trace element composition of endorheic saline lakes (with total dissolved solids varies from 1 to 590 g/L) of the Altai Region (Russia) is of undoubted interest from the point of view of their mineral resources. Among the trace elements in lake waters, high content of boron (up to 78 mg/L), bromine (up to 820 mg/L), lithium (up to 3.6 mg/L), strontium (up to 13 mg/L), iodine (up to 6.3 mg/L), and arsenic (up to 0.6 mg/L) have been determined. The content of uranium in the investigated lakes varies over a wide range (9.2*10-4- 4.1), average is 0.3 mg/L. It is shown that soda lakes are characterized by accumulation of U, As, Si, Mo; high content of Sr and Li are specialty of chloride lakes. The article presents that amount of trace elements in bottom sediments of studied lakes is closely connected with water-rock interaction processes and migration features of element in brackish solutions. Such elements as Si, B, As preferentially migrate in HkMeOn m-form; Br and Mn, on the contrary, only in the form of pure ion; Ni, Cu, Th, U, Al, and Fe migrate in complexes with organic matter. © SGEM2017 All Rights Reserved. |
