Abstract - This work is an attempt to determine the real time of formation of coastal-marine placers based on the modeling of placer-forming processes, present-day rates of lithodynamic processes, and recent parameters of placer sources. The result obtained shows that the real time of formation of the Val'kumei tin placer (Chaun Gulf, East Siberian Sea) significantly differs from its stratigraphic age. Possible reasons of this discrepancy are analyzed.
