Résumé(disponible en anglais seulement)
Surficial 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.

Rapport sur le travail collaboratif sur le terrain de la Commission géologique de Terre-Neuve-et-Labrador, ainsi que sur les activités de terrain 2016 de cartographie des depots de surface de GEM2 Hudson-Ungava . Ce rapport est rédigé par Heather Campbell, géologue de surface qui collabore avec notre activité GEM2 et sera publié par le gouvernement de T-N & Labrador avec les co-auteurs de la CGC. Ce rapport résume nos observations sur le terrain et discute des principales unités de sédiments superficiels.
