Summary:

An analysis of the conditions for the formation of gold placers in the mountainous part of the Southern Urals using the Krasnokhtinskaya multi-layer placer as an example shows that the most productive are the Eopleistocene and Middle Neopleistocene cycles of placer formation, associated with the II (final) stage of the successive-intermittent neo-orogenic uplift of the territory. Miocene placers corresponding to the first stage of neo-orogenesis in the Central Ural Uplift (CUU) are not industrial. On the eastern slope of the Southern Urals, unlike the CUU, the Eopleistocene erosional incision did not reach the Miocene level; their levels are close together and multi-layer placers are also formed in them (Novo-Marininskaya, Nepryakhinskaya).
