Use of geochemical indicators to determine the genesis of sylvinite of the Tubegatan deposit

This article presents the results of study of salt rock from productive bed "nizhniy 2" of the Tubegatan potash deposit located at the southern territory of the Uzbekistan Republic. Analysis of structural and textural features of the studied sediments showed that they were recrystallized. Calculated geochemical indicators, such as bromine-chlorine ratio and rubidium-potassium ratio, confirmed the conclusion about the secondary origin of some sylvinite beds from carnallite strata. It is shown that the formation conditions of the "nizhniy 2" sylvinite bed were similar to those of Karlyuk deposit and to multi-colored sylvinite from bed "B" of the Verkhnekamskoe deposit (Upper Kama potash deposit).
