This dataset is the digital compilation of Lake Sediment Analyses was done by the GSC for the Precambrian Shield area of Saskatchewan. This dataset represents the water and sediment geochemistry for select lakes in Saskatchewan. This product was produced by the Geological Survey of Canada as Open file 7746. During the intense level of activity directed toward the exploration for uranium in the 1970s, the Saskatchewan Geological Survey and the Geological Survey of Canada funded the collection of several thousand samples of sediments and waters from lakes around the Athabasca Sandstone. All sediment samples were analyzed for U, Cu, Ni, Pb, Zn, Co, Fe and Mn. Selected samples were analyzed for a wide range of additional elements. All lake waters were analyzed for U, F-, and pH, and several hundred samples were analyzed for additional elements and parameters. The Summary Table that precedes this text shows the numbers of samples and elements, and the source of data from which the 8,939 samples listed in the 9 Tables are derived. Over 20 years ago the data in these listings were coded into the Saskatchewan Geological Survey’s ‘Geochemical Data File’, designed in the 1970s (Dunn,…
