placer deposit | geology | Britannica

placer deposit, natural concentration of heavy minerals caused by the effect of gravity on moving particles.When heavy, stable minerals are freed from their matrix by weathering processes, they are slowly washed downslope into streams that quickly winnow the lighter matrix. Thus the heavy minerals become concentrated in stream, beach, and lag (residual) gravels and constitute workable ore ...
