AbstractArchived drill-cuttings of Cretaceous sedimentary rocks from 96 wells were analyzed to provide a geochemical database and maps of a 100,000 km2 area of bedrock in central Saskatchewan. A dark shale (the White Speckled Shale) is enriched in Ca, Cd, Mo, Se, U and V (and to a lesser degree in As, Cu, Ni, Sb, Sr and Zn), when compared to other geological strata in the district. This shale subcrops beneath glacial drift near Henribourg, where there is a coincidence of structural weakness and formation water discharge. Because groundwater chemistry is controlled mostly by rock and sediment chemistry, the possibility was examined that the enrichment of some elements in the White Speckled Shale may have a bearing on the high incidence of childhood homes of Multiple Sclerosis patients at Henribourg. The lithogeochemical study provides basic data that may be of use in epidemiological studies.
