Petrogenesis of the Acasta Gneiss Complex: Ancient Rocks Revisited
chercheur principal: Reimink, Jesse R
Année(s) de permis: 2014 2013 2012 2011
Résumé: The present study aims to obtain information with the following objectives: 1) further describe, sample, and document field relationships and structures present in areas that were sampled and found to be significantly old (>3.8 billion years); 2) explore and sample other units which based on field relationships and mineralogy are likely to be as old or older than previously documented samples; and...


Petrology and geochemistry of the late Archaean banded iron formation and associated turbidites, western Slave Craton: constraints on palaeoenvironment
chercheur principal: Haugaard, Rasmus RH
Année(s) de permis: 2013 2012
Résumé: The recent discovery of new occurrences of 2.9 - 2.6 Ga old banded iron formations in the NWT have opened an exceptional opportunity to study ocean chemistry directly preceding the Great Oxidation Event (GOE). In this regard, the research group has been engaged with the Northwest Territories Geoscience Office (NTGO) to undertake field and laboratory studies of Achaean Banded Iron Formation (BIF) f...


Stratigraphy of the Misty Creek Embayment
chercheur principal: Turner, Elizabeth C
Année(s) de permis: 2013 2012
Résumé: This is a Masters of Science research project aimed at understanding the geological evolution of a deep-marine environment that existed in the northern Mackenzie Mountains between 500 and 450 million years ago. This project team will establish small 2-3 person camps on or near a mountainside which is already known, based on previous work, that the rocks they are interested in will be exposed. E...


Hydrothermal event recognition and vectoring to SEDEX ore system in shale basins, Yukon and NWT
chercheur principal: Paradis, Suzanne
Année(s) de permis: 2013 2012 2011
Résumé: The objectives of this research project are to identify some proximal (close) and distal (at a distance) mineralogical and chemical elements that will indicate that rocks in a sedimentary basin are likely or not to be rich in metals; and to understand how metals were emplaced in rocks, and how they disperse once the rocks are weathered. This has implications for the land, environment and mineral i...


Investigating the Influence of Archean Seawater Composition on the Evolution and Diversity of Microbial Metallo-Enzyme Evolution Through the Chemistry of Archean Banded Iron Formation
chercheur principal: Mloszewski, Aleksandra M
Année(s) de permis: 2011 2010
Résumé: The recent discovery of new occurrences of Neoarchan (2.8 Ga to 2.6 Ga) banded iron formations (BIF) in the Northwest Western Territories have opened an exceptional opportunity to study ocean chemistry. In this regard, the research group has been engaged by the Northwest Territories Geoscience Office (NTGO) to undertake field and laboratory studies of Archean and Proterozoic Banded Iron Formation ...


Western Imperial Formation
chercheur principal: Rose, Rachael
Année(s) de permis: 2011
Résumé: The objective of this study is to record the succession of rocks and collect some samples for further analysis. The researchers would take pictures of the rocks at the locations in order to support the interpretations made. From these observations, interpretations on the Devonian environment can be made. Rock succession and features within the rocks will be recorded in a notebook and the corres...


Petrogenesis of the Blachford Lake Intrusive Suite
chercheur principal: Mumford, Thomas R.
Année(s) de permis: 2011 2010
Résumé: With increasing activity at the Nechalacho Rare Earth Element Deposit a better geological understanding of the setting of the mineral deposit is required. This study is fundamentally concerned with how and why the deposit exists. This is achieved by studying the entire Blachford Lake intrusive suite (>300 km2), the igneous system which generated the deposit. From this, a petrogenetic framework wil...


Late Proterozoic stratigraphy of northwestern Canada and its record of Earth system evolution
chercheur principal: Halverson, Galen P
Année(s) de permis: 2014 2011
Résumé: The objectives of this study are: 1. to improve the geological, tectonic, and geochemical constraints on the emplacement of ca. 780 Ma Little Dal Basalt and associated sill and dikes and the deposition of the overlying Coats Lake Group; and 2. to improve correlation between the Little Dal Group and similar-aged strata in the Yukon Territory in order to under the origin and geometry of this sedim...


Geochemical and Mineralogical Controls on Metal Dispersal Downstream of Mineralization in the Mackenzie Mountains, Canada
chercheur principal: Skeries, Kristina A
Année(s) de permis: 2011
Résumé: The objective of this research project is to understand how metals might be weathering from rocks, and to understand where they end up and in which chemical form (the speciation). The importance is to differentiate between the metal species that weather from the rocks, the species by which they are transported, and finally, the species by which they are deposited again, if they are in fact deposit...


Regional Geoscience Studies & Petroleum Potential of the Peel Plateau and Plain, Northwest Territories & Yukon
chercheur principal: Jones, Adrienne
Année(s) de permis: 2007 2006 2005
Résumé: The Peel Plateau and Plain is a region of under-explored hydrocarbon potential. Bedrock mapping and exploration drilling was done in the 1960s. The objective of this project is to improve knowledge of regional geology, including stratigraphy; correlation, depositional and tectonic histories; basin evolution; and petroleum geology and potential. Reconnaissance work will be conducted in the Peel Pla...
