ProgramHudson/Ungava Core Zone, GEM2: Geo-mapping for Energy and Minerals
Released2015 12 02
This activity report summarizes accomplishments of the GEM 2 Hudson-Ungava surficial activities focused on northeast Quebec and west central Labrador. These activities are being carried out in collaboration with the Ministère de l'Énergie et des Ressources Naturelles du Québec (MERNQ) and the Geological Survey of Newfoundland and Labrador (GSNL). This report complements the first year's activity report published by McClenaghan et al. (2014). The study area is underlain by Precambrian rocks of the New Quebec Orogen and southern Core Zone. Surficial sediment and landforms include thin veneers of glacial sediment (till), thicker glacial deposits of ribbed and streamlined sediment, small esker systems, and glacial lake deposits in low lying areas.
The overall objective of these activities is to produce new regional geoscience data including surficial geology, and geochemistry and radiometric 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, geochemical database management and gamma ray spectrometry studies.
Surficial mapping 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. Laboratory work led to improved sample processing and examination techniques for till samples. Data management has facilitated web access to GEM 1 and GEM 2 publications and data.
Summary(Plain Language Summary, not published)
This open file reports activities carried out as part of the GEM-2 Program in the south Core Zone of Quebec and Labrador in 2014 and 2015. These activities include surficial mapping, till and lake sediment geochemistry, and gamma ray spectrometry mapping studies.
