5203 |a"This report presents new geochemical data, quality assurance and quality control (QA/QC) results of the reanalysis of lake-sediment samples collected from northern Manitoba (NTS 64-J and 64-K). The original sampling programs were conducted in 1975, whose results are presented in Geological Survey of Canada open files 320 (NTS 64-J) and 321 (NTS 64-K). Lake-sediment samples from 2 005 sites were reanalyzed between 2020 and 2022 and included (i) samples from 1 798 regional-scale sites, covering an approximate area of 26 000 km², with an average density of one sample per 13 km², and (ii) 208 samples from sites from more detailed sampling programs conducted in the same year, in the northwest and northeast corners of NTS 64-J and NTS 64-K, respectively, with an average density of one sample per 7 km² over an area of approximately 3,000 km². In the recent re-analysis, samples were measured for 65 elements via modified aqua-regia - ICP-MS, and for 35 elements by INAA. To ensure high-quality geochemical data, the data were evaluated for accuracy, precision, and fitness-for-purpose. QA/QC results have identified several elements to be monitored carefully for future analyses"--Abstract, page 1.
