The article concentrates on relation of mineralization, granitoid magmatism and dikes in ore fields of the Eastern Yakutia with cassiterite-sulfide mineralization. It is shown that, the main ore bodies are confined to places of intensive development of dikes and do not significantly concur with the time of granitoid formation. The melts that formed dikes and generated into metasomatised mantle, was the main source of tin and accompanying elements. When centers of granitoid and dike eruption are the same, these melts were additional sources of heat and volatile components, that provided duration of granite system evolution and additional mobilization of ore material.
