AbstractMerging of geochemical datasets from neighbouring regions, compiled during differently administered programs, in order to create seamless geochemical maps is complicated due to factors such as differences in sampling methodologies and analytical protocols, and sample densities. In this study, a suite of 5,510 lake-sediment samples from western and northern Labrador has been re-analyzed by
ICP-MS after aqua-regia digestion, in order to merge the results with a suite of 26,727 lake-sediment samples collected in an adjacent area of the province of Quebec, analyzed by the same method. This merging of datasets has enabled the creation of regional geochemical maps of a contiguous area in northeastern Canada of almost 300,000 km2. This activity is one of several surficial geochemistry and mapping activities in northern Quebec and Labrador that form part of the Geological Survey of Canada's Geo-mapping for Energy and Minerals (GEM-2) Program (2013-2020) (McClenaghan et al. 2016). The purpose of this article is to report on the old and new lake-sediment datasets and about the ongoing production of new lake-sediment geochemical maps for the Quebec-Labrador region that will be published in the first half of 2017.
