Isotopy and morphology of the newly formed carbonates of the Ledynaya gora carbonate-sulfate massif

The morphology, isotope, and chemical composition of newly formed carbonates of the Ledynaya Gora carbonate-sulfate massif in various microclimatic zones of the Kungur Ice Cave are considered. It was found that composition of newly formed carbonates is influenced by their location in the geological section. In weathering crust they are characterized by lack of impurities, but, below, they demonstrate the variation in composition. It allows associating them with the secondary enrichment zone related to a carbonate barrier. Calcite prevalence at the top of weathering crust allows assuming that newly formed minerals are not a transformation product of basic material of the carbonate member of the Irensky Suite and formed due to interaction of sulfate-calcium waters with atmospheric or biogenic carbon dioxide. Studying of newly formed carbonates from different microclimatic zones of the Kungur Ice cave showed that temperature does not affect the composition of newly formed minerals, and influences only their morphology and variations of carbon isotope composition.
