AbstractDespite a long history, lacustrine research on the western Canadian Great Plains has only recently focused on understanding the complex, interactive physical, chemical, and biological processes that characterize modern lakes. These lakes exhibit tremendous diversity in terms of hydrology, morphology, chemical composition, and sedimentary processes. Although many basins exhibit playa characteristics, the region also contains several of North America's largest lakes. Salinity and ionic composition show great diversity, with virtually every type of water chemistry represented. Associated with this large range in brine chemistry is an equally diverse assemblage of endogenic and authigenic minerals. Although investigation of the Holocene stratigraphic records in these basins is in its infancy, some approaches, such as deciphering paleochemistry and paleohydrology from the endogenic mineral record and isotopic composition, have proven to be successful. Challenges for both fundamental and applied researchers are to integrate, on a regional basis, the sedimentological and geochemical complexities exhibited by modern lakes with the preserved stratigraphic records.
