Mössbauer studies of the spectra of 57Fe nuclei in Late Cenozoic endogenous formations of the Eastern Caucasus

详细

Three types of manifestations of Late Cenozoic endogenous activity (pyroclastic, hydrothermal explosive, and volcanogenic sedimentary formations) have been found over the last decade in different geostructural zones of the Terek–Caspian foretrough and the Alpine fold–thrust structure in the Eastern Caucasus. The results from Mössbauer studies show that these formations contain fractions of iron and its compounds with complex crystal structures in which ⁵⁷Fe atoms occupy nonequivalent positions in the lattice with respect to their magnetic and electric fields, exist in different physicochemical states, and occur in various phases of the endogenous process products.
