This report describes field work carried out as part of the Geological Survey of Canada's Targeted Geoscience Initiative indicator mineral research activities at the Brazil Lake Li-Cs-Ta pegmatites in southwest Nova Scotia. This research is being undertaken in partnership with the Nova Scotia Department of Natural Resources and Renewables (NSDNRR). In the fall of 2022, 44 till samples were collected around and down-ice of the Brazil Lake Li-Cs-Ta pegmatites to document the geochemical and indicator mineral signatures of the pegmatites in the till. In 2020, 2021, and earlier in the summer of 2022, 105 till samples were collected across southwest Nova Scotia by the NSDNRR to provide regional context for the interpretation of the 44 case study samples. Till samples were also collected at the Salmon River beach section ~25 km north of Yarmouth where a thick coastal exposure (> 20 m) contains multiple till units that reflect several phases of glacial deposition and shifting ice-flow directions across southwest Nova Scotia. These section samples will provide insight and additional details on the regional glacial context. |
