ProgramRae Province, Tehery-Wager Bay, GEM2: Geo-mapping for Energy and Minerals
AbstractTargeted field work during the summer of 2015 in the eastern part of the Tehery-Wager GEM2 Rae Project area, mainland Nunavut, has provided an opportunity to gather data on the history and pattern of glacial flow and ice margin retreat, collect till and stream sediment samples for provenance and evaluation of mineral potential, and test preliminary remote predictive mapping (RPM) surficial materials classification maps with field observations. The work was undertaken to provide new geological knowledge on the nature and composition of surficial sediments deposited during previous glaciation(s), successive marine inundation and emergence. It will address a number of scientific questions relevant to the mineral exploration industry, including: 1) what is the nature of glacial transport in proximity and distal to the Keewatin Ice Divide; 2) what is the age of the weathered bedrock terrain under the ice divide and potential for preservation of an older, relict landscape under a cold-based glacier regime; 3) what is the limit of post-glacial marine inundation, glacial retreat pattern and chronology, and influence on surficial sediment composition and redistribution; and 4) how can we improve on current remote predictive mapping methods to enhance surficial geology mapping and field methods. Future work will include data and map compilation, sample analysis, and interpretation.
Summary(Plain Language Summary, not published)
This poster presents an overview of the 2015 field work completed along the northwestern shores of Hudson Bay, mainland Nunavut, as part of the surficial geology component of the GEM-2 Tehery-Wager Activity within the Rae Project. The poster highlights preliminary results regarding the regional surficial geology and Quaternary history, the mapping of surficial materials using remote sensing, and the applications of glacial and stream sediment sampling for mineral exploration. The work was undertaken to provide new geological knowledge on the nature and composition of surficial materials deposited during the retreat of the Laurentide Ice Sheet, successive marine inundation and emergence, and addresses a number of scientific questions relevant to the mineral exploration industry. The findings will support informed decision making for resource exploration and development, and for land use management.
