Source apportionment of lake bed sediments to watersheds in an Upper Mississippi basin using a chemical mass balance method

Authors(s) and Affiliation(s)



The aim of this study was to develop a method of assessing the sources and depositional record of historic sediments in a lake basin with a large catchment, and reconstruct how sediment provenance changed over time. The AA. first used known mixtures of source samples to test the method, then applied the technique to a field sample from a depositional basin. The site selected for sampling encompassed 3 large, contiguous catchments in the USA (headwater-Mississippi, Minnesota, and St. Croix), that deliver sediment to an isolated depositional basin, Lake Pepin. The beds of each river system are composed of sediments derived from glacial deposits of different ages and geographic origins, so the method should effectively distinguish the different sources
