In the metallogenic analysis of Precambrian terranes that have undergone a long and complex history of formation, the analysis of ore-forming cycles is of great importance. Multiple processes of activation and regeneration of previously created ores lead to the emergence of polychronous and polygenic deposits and to the leveling of structural and ore parageneses. Geodynamics makes a significant contribution to these processes, reflected in the material composition and metallogenic specialization of the basic-ultrabasic and alkaline magmatic complexes. Assessment of the composition and conditions of formation of magmatic complexes contributes to the typification of ore objects of various ages, forecasting deposits. The paper considers complexes associated with deposits of iron and gold, high concentrations of copper, nickel, cobalt and platinum in the central part of the Aldan-Stanovoy shield. The study of geochemistry and mineral composition of rocks was carried out. A small comparison was made with Precambrian ore-bearing igneous rocks of the Siberian Platform and the Baltic Shield. It was found that the chemical and mineral composition of most of the rocks is similar to the svecofennian intrusions of the Kotalakhti ore belt on the territory of the Baltic Shield. The conclusion is made about similar conditions of formation and prospects of ore bearing.
