Regularities of Noble Metals Distribution in Halogenous Formations of the Pre-Ural Marginal Trough

The results of the determination of noble metals in rock salts are shown: oil and gas fields of Sakmaro-Ileksky, Yuzhno-Buzuluksky, Sol-Iletsky, Teplovsky-Derkulsky oil and gas and geological regions and Iletsky salt deposit. Platinum, palladium, gold and silver were determined in the samples of the Kungur stage of the Irenian horizon by atomic absorption spectrometry using their own patented method. Elevated levels of all noble metals have been established. In addition, higher concentrations of platinum, palladium, gold and silver occur in rock salts associated with hydrocarbon fields. Perhaps this indicates the presence of a geochemical barrier at the interface between hydrocarbon and halogen media. The above facts of the detection of noble metals in the strata of rock salts of the Orenburg Pre-Ural marginal trough are also of practical importance, demonstrating the relationship of elevated metal concentrations with halogenesis and the effects of salt tectonics.
