Preliminary information on the chemical; and isotopic compositions of waters from the Caspian Sea and its tributaries in the Makachkala region (Russia)

Abstract:

The δ18O and 87Sr/ Sr values of thermal waters from the western coast of the Caspian Sea, which contribute to its total budget, result from interactions with host rocks; they even suggest a supply by 'deep' waters. In fact, the Sr contents and the 87Sr/86Sr values of the river and thermal waters are not sufficient for the calculation of an equilibrated budget, implying that other sources contribute to the budget of the Caspian waters. The 206Pb/207Pb ratio of the waters from the Sulak river also suggests local anthropogenic pollution.
