DOI: 10.1007/s00126-017-0789-6
Abstract: Formation of placer accumulations in fluvial environments requires 103–106 or even greater times concentration of heavy minerals. For this to occur, regular sediment supply from erosion of adjacent topography is required, the river should remain… read more here.
