Physical Rock Property Compilation – Boothia Peninsula – Somerset Island, Laying the Foundation for Geophysical Data Modelling and Interpretation

Proponent: Brock University

Project Leader: Dr. Hernan Ugalde

GEM region of interest: Rae

GEM priority theme(s): Metallogeny of northern Canada; Evolution of Canada’s northern sedimentary basins; Crustal architecture of northern Canada

 

Objectives:  The objective of this Project is to measure magnetic susceptibility, gamma spectrometry, conductivity, and NVIR spectrometry data on 1200 samples collected during the 2017 field season.  This GEM-2 Grant proposal is supporting the GEM-2 Boothia Peninsula – Somerset Island project that provided modern geoscience for the underexplored, politically important Northwest Passage region, where knowledge stems from 1963 and 1986-92 without prior benefit of aeromagnetic constraints or modern geochronology. Data acquired, including new regional aeromagnetic data, will collectively elucidate the extent, age and character of crustal domains; establish the location, timing and impacts of sites of rifting and collision; assess mineral resources attributed to, and affected by, these complex interactions; and collectively lay the foundation for sustainable economic development across the North.  To date, the aeromagnetic data has been utilized to trace the extent of geological units under glacial till and Paleozoic cover.

Benefits to Canada:  This project utilizes geological field and state-of-the-art analytical techniques that will significantly advance and modernize the geological knowledge of Canada’s North, including the metallogeny of economically relevant rock units. Because the proposed Project takes place at established and high-capacity laboratory facilities in Canada, there is a great potential for high-impact products that can contribute new information to bedrock mapping programs in the GEM-2 regions of interest.

Tectonometamorphic evolution of the Core Zone, South-East Churchill Province, Québec

Proponent: Université Laval

Project Leader: Dr. Carl Guilmette

GEM region of interest: Hudson-Ungava

GEM priority theme(s):  Metallogeny of northern Canada; Tectonothermal evolution of northern Canada; Crustal architecture of northern Canada

Objectives:   The objective of this project is to use geochronology to better constrain metamorphism in that segment of the Tasiuyak gneiss that is undisturbed by the Abloviak shear zone.  This work is part of the Proponent’s more extensive Tectocore project that is focused on assessing the extent, intensity and timing of tectonometamorphism in the various domains that comprise Quebec’s Nunavik area (i.e. New Quebec Orogen [NQO], Torngat Orogen [TO] and the Archean Core Zone [CZ] gneiss block).

Benefits to Canada:  This project, coupled with the results of the Proponent’s significantly more extensive Tecotocore initiative, supports the development of a modern geological knowledge framework for this relatively poorly studied part of Labrador/Quebec, which in turn could draw the attention of the scientific and industrial communities to the Hudson-Ungava region.

Using Ca and Mg Isotopes to Track Fluid Flow in the Lake Mesoproterozoic Borden Basin, Baffin

Proponent: McGill University

Project Leader: Dr. Galen Halverson 

GEM region of interest: Baffin

GEM priority theme(s): Metallogeny of northern Canada; Evolution of Canada’s northern sedimentary basins

Objectives:  The objective of this project is to use Calcium (Ca) and Magnesium (Mg) isotopes to understand the history of fluid flow through late Mesoproterozoic carbonate platforms of the Bylot Supergroup.

Benefits to Canada:  The new data generated as part of this project will be integrated with existing databases from late Mesoproterozoic sedimentary rocks of northern Baffin Island and used to develop a more thorough model of the depositional and alteration history of an economically important sedimentary basin.

Mineralogy, Macro, Trace, and Rare Earth Element Analysis of Selected Precambrian through Tertiary Bylot and Baffin Island Strata

Proponent: Memorial University of Newfoundland

Project Leader: Dr. Elliott Burden

GEM region of interest: Baffin

GEM priority theme(s): Metallogeny of northern Canada; Evolution of Canada’s northern sedimentary basins; Thermochronology and low temperature thermal history of northern Canada; Crustal architecture of northern Canada

Objectives:  The objective of this project is to construct a large geographically extensive collection of rock lithology and chemical data for some Cretaceous and Tertiary strata of the eastern Arctic.

Benefits to Canada: This data will provide a better understanding of the structure, regional bedrock stratigraphy and resource potential of Cretaceous and Tertiary strata of the eastern Arctic, which may be useful in the development of more informed mineral exploration strategies on Baffin Island.  Parks Canada can use the project data to better interpret the basic geology and structure of the Bylot Island National Park, and add to the ecotourism potential of the region.

Dating Metamorphism in the Tantato Domain using Lu-Hf Gamet Geochronology

Proponent: University of British Columbia Okanagan

Project Leader: Dr. Kyle Larson

GEM region of interest: Rae

GEM priority theme(s): Tectonothermal evolution of northern Canada; Crustal architecture of northern Canada

Objectives: The objective of this Project is to use Lutetium-Hafnium [Lu-Hf] age dating to derive new constraints on the timing of metamorphism for rocks on either side of a large, poorly understood shear zone in the Tantato Domain of Northern Saskatchewan.

Benefits to Canada: The area that will be examined in northern Saskatchewan is part of a Geo-mapping for Energy and Minerals (GEM) priority research area.  This project will help elucidate some of the targets specified by GEM and contribute to a better understanding of the geological history and potential metallogenic significance of northern Saskatchewan’s Tantato Domain.

Multivariate Analysis of Till Composition in the Hudson Bay Lowland:  Implications for drift Prospecting

Proponent: University of Waterloo

Project Leader: Dr. Martin Ross

GEM region of interest: Hudson-Ungava

GEM priority theme(s): Glacial history and drift prospecting of northern Canada; Crustal architecture of northern Canada

Objectives: The objective of this Project is to develop a geochemical classification of glacial sediment (till) from northeastern Manitoba to improve understanding of their composition from a mineral exploration point of view and to assess the potential for a buried Precambrian inlier with economic potential.

Benefits to Canada: The project will provide new geosciences knowledge about an underexplored region within the Hudson-Ungava area, advancing the understanding of glacial history in northern Canada.  Results will support ongoing mineral exploration and/or attract new investments.  Additionally, this project will train highly qualified personnel ready to contribute to the Canadian geosciences workforce.
