The paper shows the main characteristics for geological and associated ore formations in the Tungusik formation complex. Ore formation deposit types and ore field types in the region are identified and described. Based on the identified lithofacies, the paleoenvironment of stratiform ore associations formation is characterized. The role of metamorphism and structural factors affecting prospecting conditions are shown. The relationship between the mineral type of ores and organic carbon content in ore-bearing strata for various geological and economic types has been revealed. The obtained and generalized data are of practical interest in designing forecasting/prospecting deposit models and improving prospecting efficiency.
