Abstract:
The future of Southern Aral Sea water in Kazakhstan, and of the sequence of mineral evaporitic sediments precipitated since the beginning of the present regression from gypsum to bloed-ite (astrakhanite) was studied. A comparison is made with previous regressive deposits discovered earlier in cores by I.V. Rubanov. Absence of mirabilite deposits in sediments of the eastern basin is attributed to deflation processes during the XIVth century AD.
