AbstractSurficial geological mapping and till-geochemistry sampling were completed in the southwestern quadrant of the Woods Lake map area in western Labrador. This project is a collaboration between the Geological Survey of Canada and the Geological Survey of Newfoundland and Labrador as part of the Geo-mapping for Energy and Minerals-2 program. This project was developed to better understand ice-flow patterns of the Labrador Ice Centre, characterize glacial landscapes and to determine glacial dispersal, sediment transport and deposition of glacial material northwest of the Smallwood Reservoir. This area was chosen as a focus for surficial mapping as there is a paucity of bedrock outcrops, and an understanding of complex glacial dispersal patterns from the Labrador ice cap would provide insight into glacial dispersal from source rocks and mineralized outcrops. A total of 54 till samples were collected for geochemical analysis from mudboils in discontinuous permafrost terrain or hand dug holes in non-permafrost regions. Additionally mapping observations, such as surficial unit (e.g., till veneer, bedrock, glaciofluvial sediment), surficial landforms (e.g., crag-and-tail forms, flutings, ribbed terrain) were recorded at each sample station. Observations of landforms and striae indicate a complex glacial history with a minimum of three different ice flow directions and four glacial events.
Summary(Plain Language Summary, not published)
Report on collaborative fieldwork from the Geological Survey of Newfoundland and Labrador, along with GSC GEM2 Hudson-Ungava Surficial 2016 field activities. This report is authored by Heather Campbell, the surficial geologist collaborating with our GEM2 activity and will be published by the NFLD government, with GSC co-authors. This report summarizes our field observations and discusses the major surficial sediment units.
