Geological Structure of the Kumak Ore Field (Southern Urals, Russia),The article considers the geological structure of the Kumak ore field. Particular attention is paid to the carbonaceous shales of the Bredy Formation (C.bd), which compose elongated submeridional blocks of the Anikhov graben. The rocks are saturated with carbonaceous matter to varying degrees.

The Concept of Industrial Development of Gold Deposits in , Kumak Ore Field (Southern Urals, Russia been identified: weathering crusts and primary deposits. The use of underground and heap leaching methods will make it possible to conduct more efficient industrial mining of gold objects, replenish the balance of mineral reserves in the Orenburg region.

Standortbestimmung der Tokolysebehandlungposited in a transitional geodynamic setting from riftogenic to collisional. Black shale deposits of the Kumak ore field according to the parameter Na.O/K.O = 0.62 belong to normal-potassium formation type, typical for deposits mainly with gold-sulfide mineralization.

The close intergrowth of thin acicular tourmaline and gold indicates the synchronism of their formation and allows us to attribute the manifestations of the Kumak ore field to the quartz-tourmaline ash formation.
