Geochemical Characteristics Infiltration Deposits Kungur Ice Cave (Preduralie)

Abstract

—The results of spectral analyses of infiltration deposits of a large karst system in carbonate-sulfate deposits are presented. The movement of loose material from the surface through deformation zones within an array with a capacity of 80–90 m leads to accumulations of gravel-clay deposits in the lower part of grottoes and galleries. The localization of deposits is confined to certain forms of underground karst relief – organ pipes: vertical structures up to 20–25 m high, free or filled with debris. Regularities in the distribution of individual oxides and elements are revealed, their values are compared with residual deposits, as well as matrix rocks. Infiltration waters entering the karst massif in the pre-paleogenic stage determined the conditions for the formation of cryogenic minerals during the freezing of rocks. The cyclical nature of the material intake is compared with the periods of Late Pleistocene climatic events.
