This report is a summary of GSC field work, lab work, and data compilation carried out between April and September 2014 for the surficial geology component of the GEM 2 Hudson-Ungava project. The activities are focused on northeast Quebec and west central Labrador and are being carried out in collaboration with the Ministère de l'Énergie et des Ressources Naturelles du Québec and the Geological Survey Newfoundland and Labrador. The study area is underlain by Precambrian rocks of the New Quebec Orogen and southern Core Zone. Surficial sediment cover consists of thin veneers of glacial sediment flanked by thicker glacial deposits of ribbed and streamlined sediment, small esker systems, and glacial lake sediments in low lying areas. The overall objective of these activities is to produce new regional geoscience data including glacial transport trends and surficial geology and geochemistry maps, to support natural resource exploration and responsible resource development in the Hudson-Ungava region. Activities include surficial and bedrock mapping, till geochemistry and indicator mineralogy, lake sediment geochemistry. Field work led to an improved understanding of the surficial and bedrock geology of the study area and identification of key areas for more focused mapping and sampling in subsequent field seasons. Lab work led to improved sample processing and examination techniques for till samples. Data management has facilitated access to GEM 1 and GEM 2 publications and data.
Summary(Plain Language Summary, not published)
The GSC in collaboration with the Ministère de l'Énergie et des Ressources Naturelles du Québec and the Newfoundland & Labrador Geological Survey are conducting new surficial mapping and surficial geochemical studies as part of an integrated regional mapping program in the Core Zone in northeast Quebec and west central Labrador between latitudes 54°N and 56°N, and longitudes 64°W and 66°W in NTS maps 23I and 23P. GEM-2 surficial activities being carried out in this region include surficial mapping, till geochemistry and mineralogy, and lake sediment geochemistry. They will result in new regional geoscience data and knowledge that will be used to promote natural resource exploration and responsible resource development.
