The Zeemal Heaton Lake metasedimentary assemblage comprises ~50% of the eastern limb of the North Caribou greenstone belt, which hosts the Musselwhite gold deposit (~ 5.4 Moz Au). The metasedimentary assemblage is divided into two based on their distribution: the Central-belt and North-rim of the belt. The Zeemal Heaton Lake metasedimentary rocks have been interpreted to represent a turbidite succession, consisting of pelite, arkose, wacke and conglomerate. Detrital U-Pb zircon age populations from this study indicate variable sources in the Central-belt metasediments with a maximum age of deposition of 2798.8 ± 29 Ma, while metasediments along the North portion of the limb display a maximum age of deposition of 2696 ± 39 Ma. This indicates the likelihood of two discrete basins with the Zeemal Heaton Lake assemblage. Neodymium isotopic values for the sedimentary rocks along the North-rim of the belt display εNd2680Ma ranging from -1.2 to -0.9. An overlapping but slightly more evolved signature shown in the Central portion with values of εNd2800Ma -1.6 to 0.1. This indicates detritus for the Central-belt was likely sourced from the older (~2850 Ma), (tonalite-granodiorite) surrounding intrusions. The North-rim sediments were sourced (in part) from the younger (~2700 Ma) granitic intrusions and rhyolites. The surrounding batholiths display εNdt overlapping with North-rim sedimentary rocks, however, indicate significant contribution beyond these immediate surrounding batholiths, which may include older mafic (2982 ± 0.8, 2870 ±2 Ma), younger rhyolitic unit (2723 ± 2 Ma) or more distal sources than the intrusions immediately adjacent to the belt. Peak metamorphic mineral assemblages indicate a minimum of amphibolite facies-garnet zone or greater across the Central-belt portion of the greenstone belt. The North-rim metasediments display evidence for aureole metamorphism which may overprint earlier regional metamorphism. Nitrogen abundance and δ15N values of biotite of the Zeemal Heaton Lake metasedimentary assemblage indicate variable values than those associated with mineralization at the Musselwhite Mine, which is reported by Isaacs (2008). Mineralizing fluids from the Musselwhite mine have been interpreted by Issacs (2008) to be related to both metamorphic and magmatic fluids. Fluids associated with the Eyapamikama and/or Zeemal Heaton Lake metasediments appear to be metamorphic with minor magmatic influence near regional shear zones, but not directly related to the auriferous fluids which formed the Musselwhite mine.

Ce mémoire vise à approfondir les débats sur la participation politique des Autochtones au Canada, en particulier les jeunes. Les recherches sur le sujet concluent que la participation électorale est plus faible chez les personnes autochtones et que cette différence est encore plus marquée chez les jeunes. Si plusieurs raisons peuvent expliquer ces plus faibles taux, les études soulignent en particulier le cynisme et l’aliénation causés par les politiques coloniales. À première vue, on pourrait donc penser que les jeunes Autochtones représentent une catégorie dépolitisée et désengagée d’individus. Pourtant, nous montrons dans la présente étude que le portrait est plus complexe. Grâce à des entrevues conduites auprès de six jeunes Anishinaabe de la communauté de Timiskaming First Nation, nous pouvons affirmer que s’il y a bel et bien un certain cynisme et un désengagement chez ces jeunes face à la politique comprise de manière formelle, comme la participation électorale, l’implication au sein d’un parti ou même la participation au sein de leur conseil de bande, cela ne veut en aucun cas dire qu’ils sont passifs ou dépolitisés. Ces jeunes sont fortement impliqués au niveau communautaire et dans le processus de revitalisation et/ou de protection culturelle de leur communauté. Même si ces jeunes n’articulent pas nécessairement ces actions comme étant de nature explicitement politique, elles témoignent d’une volonté d’agir sur la communauté qui relève bel et bien de l’engagement politique. Sur la base de cette étude, nous invitons donc à nuancer les travaux qui concluent au désengagement des jeunes Autochtones. / This thesis contributes to the debates on political participation of Indigenous youth in Canada. Existing research shows a significantly lower electoral participation rate among Indigenous individuals, especially Indigenous youth. This low participation rate is explained, among others, by a high level of cynicism and a sense of alienation resulting from colonial policies that discouraged political engagement among Indigenous peoples. We may therefore think that Indigenous youth are depoliticized and disengaged. This research shows a more complex reality. Thanks to in-depth interviews with six young Anishinaabe members of the community of Timiskaming First Nation, we conclude that they are indeed somewhat cynical concerning formal modes of political participation, such as voting, joining a party or even working for the Band Council of their community. However, they are also strongly involved in community work and in cultural revitalization and protection activities. Even if these youths do not consider such activities as political, they do testify to a desire to change their community that is arguably political. This study therefore provides a more nuanced portrait than existing studies on the political disengagement of Indigenous youths.
