N2 - Abstract: Isotope study of ore-bearing rocks at Fe–Mn rift deposits of the Atasu and Zhezdy (Dzhezdy) ore districts in Central Kazakhstan has been carried out for the first time. The Atasu felsic effusive rocks (Ushkatyn-1 deposit), synchronous to ore genesis, were formed at the boundary between the Frasnian and Famennian (373 ± 4 Ma). The Zhezdy ore-bearing gravelites began to accumulate not earlier than the end of the Early Devonian (after 400 Ma), but before the felsic volcanism impulse at the turn of 370 Ma. The data obtained can be indicative of asynchronous Fe–Mn deposition in the Zhezdy and Atasu ore districts.
