- Аннотация: The Yuryuzan–Sylva Depression, а part of the Uralian Foredeep, is filled with flysch-molasse complexes dated to the interval from the Moscovian Stage of the Middle Carboniferous to the Artinskian Stage of the Lower Permian. Nine samples for geochronological studies were collected from different levels of the section for extraction and the subsequent dating of detrital zircons. The distribution of Precambrian zircons in the total zircon population is of particular interest. The proportion of Precambrian zircons generally decreases from 97 to 4% from bottom to top. At the same time, the age distribution spectra of these zircons are similar throughout the section, suggesting a single source for them. In addition, these spectra are similar to those of zircons from the Vendian Asha Group of the Bashkir Megazone, which, apparently, was the source of Precambrian zircons for the Upper Paleozoic formations of the Yuryuzan–Sylva depression. The Riphean rift-related complexes of the Bashkir Megazone and the Archean–Early Proterozoic complexes of the Taratash high were not included in this provenance area.
