| Abstract | This report presents the geochemical data, quality assurance and quality control (QA/QC) results of the reanalysis of lake sediment samples collected from east-central Labrador (NTS 013-I, 013-J, 013-K,
013- N, and 013-O). The original lake surveys were conducted in 1977, 1978, 1983, 1987 and 1992, and the reanalysis was initiated in 2022. Original survey results are presented in Geological Survey of Canada open files 513, 558, 997, 1636, 1637,
2645, 2646, 2648, and 2650. Lake sediments from 3 736 archived site samples were re-analyzed, covering an approximate area of 44 000 km2, with an average density of 1 sample per 18 km2. Samples were measured for 65 elements via modified aqua-regia -
ICP-MS. To ensure high quality geochemical data, the data were evaluated for accuracy, precision, and fitness-forpurpose. QA/QC results have identified several elements to be monitored carefully for future analyses. |
| Summary | (Plain Language Summary, not published)
Lake sediment samples collected in Labrador between 1977 and 1992 and analyzed for 13 to 17 elements were reanalyzed by current methods for 65
elements. |
