摘要：
The analysis of stable S, C, and O isotopes in minerals combined with the results of structural studies of orogenic gold deposits in carbonaceous shales of the Main Uralian Fault in the South Urals reveals that orogenic gold mineralization was formed during two stages of Late Paleozoic collisional deformations: early (thrust formation) and late (wrench faulting). The leading role in hydrothermal ore-forming systems of the first stage belonged to fluids of metamorphic origin, while at the second sage they were magmatogenic.
