Full textThe Portneuf-Mauricie Domain, located in the south-central part of the Grenville Province, is composed mainly of metasedimentary and metavolcanic rocks of the Montauban group (1.45 Ga), which are crosscut by La Bostonnais complex plutons (1.40–1.37 Ga). This assemblage was formed in a magmatic arc setting. The sequence was intruded by mafic and ultramafic intrusions hosting Ni-Cu±platinum-group element (PGE) prospects and one former mine. The mineralized intrusions were emplaced into a mature island arc between 1.40 and 1.39 Ga, at the volcanic front of the arc. An exception is the Lac à la Vase intrusion, which was formed in a back arc setting. Geochronological results and the geodynamic setting related to their formation indicate that these intrusions belong to the La Bostonnais complex. The lithotectonic evolution of the Portneuf-Mauricie Domain began at 1.45 Ga with the formation of the Montauban island arc, which was associated with a northwest-dipping intraoceanic subduction zone offshore from the Laurentian continent. At the same time, the continental margin was also the site of northwesterly directed Andean-type subduction. Between 1.45 and 1.40 Ga, this Andean-type subduction led to the formation of a back arc basin behind the Montauban arc. At 1.40 Ga, the La Bostonnais complex plutons, some hosting magmatic sulfides, were injected into the Montauban arc. The intrusion of the Ni-Cu±PGE-bearing plutons ceased at 1.39 Ga, when the arc collided with the continent. Finally, intrusion of La Bostonnais complex plutons ceased entirely at 1.37 Ga. The emplacement of the Ni-Cu±PGE-bearing intrusions was facilitated by the presence of a well-developed magmatic network beneath the oceanic arc. The formation of the mineralized intrusions began with the injection of primitive, tholeiitic, hydrous, sulfide-undersaturated magmas into lower magma chambers. These magmas resulted mainly from the partial melting of a metasomatized mantle source composed of spinel-bearing lherzolite (as indicated by the trace element signatures of the intrusive rocks). During their ascent in conduits, the magmas underwent crystal fractionation and became sulfide-saturated as a result of assimilating felsic material and sulfides from the country rocks. Two main sulfide-saturation/segregation events occurred. The first may have occurred in the lower conduits. This early loss of a small amount of sulfides (less than 0.1 wt%, as suggested by Cu and Pd modeling) caused depletion of base and, above all, precious metals in the magmas. The second sulfide-separation event probably occurred in the lower magma chambers. Liquid-sulfide formation in the chambers was followed by magma–sulfide interactions (field evidence for multiple magmatic injections and R factors between 100 and 100,000) that caused enrichment of the sulfides in Ni, Cu, and PGE. Later, injections of primitive magma entered the lower chambers, and partly remobilized and transported sulfide liquid into the upper magma chambers to form the Portneuf-Mauricie Domain sulfide-bearing intrusions. The parent magmas of these intrusions, derived from the later pulses, are separated into two families. As suggested by petrologic modeling and Mg/Fe ratios, most of the intrusions may have formed from a fractionated magma (a slightly evolved magma with a Mg number (Mg#) of 60) resulting from the fractionation of a more primitive parent melt (primary magma, with Mg# = 68). All these parent magmas underwent fractional crystallization accompanied by various degrees of crustal contamination. This explains the large range of compositions observed in the mafic and ultramafic intrusions. This Ph.D. work provides new constraints for the regional evolution models proposed for the eastern Laurentian margin during the Mesoproterozoic. In addition, the petrologic and metallogenic models presented in this study contribute to a better understanding of the magmatic and metallogenic processes associated with the formation of Ni-Cu-PGE-bearing plutons in subduction-related magmatic arcs, a geodynamic setting unusual for magmatic sulfide deposits.

Full textTo ensure sustainable development in a temperate mixedwood boreal forest in central Quebec (Canada), forest managers would like to measure the historical impact of harvesting on forest cover evolution at the landscape level. The main objective of this study was to document, at the landscape level, the historical effects of harvesting on forest cover evolution and wood volume. The study was mainly based on archival records, particularly AbitibiBowater inc 's archives. The objective of the first chapter of this study was to characterize the pre-industrial forest. The main natural disturbances were big fires in 1870 and 1923 and three spruce budworm epidemics in the 20th century. Whatever the scale considered in this study, the pre-industrial forest cover was mainly composed of mature or old-growth (> 100 years) and dominated by mixedwood forest stands with intolerant hardwoods. The main forest species were white birch, black spruce and jack pine, three species associated to forest succession after fire in the boreal forest. Chapter 2 had as objectives to make an historical reconstruction of forest cover evolution in 14 landscapes and to qualify the possible effects of harvesting. For the latter, we used three analytical methods in a triangulation approach. The main alteration of forest harveting on forest cover was qualified as additive to the natural dynamic, particularly considering the increase of intolerant hardwoods. The objective of chapter 3 was to make an historical reconstruction of wood harvesting in a past forest concession (Vermillon). We monitored indicators of forest sustainability in order to discuss the impacts of forest concession revocation in 1986. In the context of our study we noted an increase of wood harvesting after the revocation. Although we were unable to conclude that the new policy was a threat to wood production sustainability, on a sustainable yield basis, our security margin has surely diminished since the introduction of the policy of 1986. “To keep in mind the actions we have done and their results” should be a leitmotiv in our forest management. At least, we should record the data collected during regular operations.

Full textThe Lemieux Dome and Sainte-Marguerite deposits are examples of epithermal and orogenic mineralization in Silurian-Devonian sedimentary and volcanic rocks of the Gaspé Peninsula. During the Silurian-Devonian, the Gaspé Belt is interpreted as a back-arc setting that eventually transformed into a transpressive setting during the Acadian orogeny. Lemieux Dome veins display mineralogical features typical of low- to intermediate-sulfidation epithermal deposits. Mineralized veins hosted by Silurian-Devonian sedimentary rocks are related to the emplacement of bimodal Devonian volcanic rocks. Mineralisation is probably coeval with volcanic rocks eruption (lower to middle Devonian), before the Acadian orogeny. The Sainte-Marguerite deposit, associated to the Acadian Sainte-Florence fault, is hosted by the Sainte-Marguerite bimodal volcanic rocks. Mineralization forms in 5 stages: (1) a calcite-chlorite stage; (2) a quartz-pyrite stage; (3) a quartz-sphalerite-galena-chalcopyrite ± arsenopyrite-adularia stage; (4) a quartz-arsenopyrite-pyrite-sphalerite stage and; (5) a quartz-carbonate stage. Stage 2 pyrite and quartz are recrystallized, indicating that sulfides formed early and were affected by Acadian metamorphism. Stage 2 pyrite and quartz were then cataclased and cemented by Stage 3 sphalerite, galena and chalcopyrite. Structural attitude of both Stage 3 and 4 veins is consistent with regional Acadian deformation during the middle to late Devonian (398 to 359 Ma), and suggests an epizonal orogenic affinity for Stage 3 and 4 mineralization, compatible with isotope and fluid inclusion data. δ18O, δ13C and microthermometric data in both deposits indicate that they were formed by infiltration of basinal brines at temperatures between 150 and 200°C. Lemieux Dome veins formed by mixing of the basinal brine with meteoric water. δ34S values and the lead isotope composition suggest that sulfur and metals were leached from surrounding sedimentary and volcanic rocks. Formation of both deposits in the Silurian-Devonian Gaspé Belt shows a mineral potential for pre-Acadian epithermal deposits, and for syn-Acadian epizonal orogenic deposits in other Silurian-Devonian rocks of the Appalachians.

Full textNature conservancy is the main goal of wilderness protected areas. Some conservation strategies, focused on concepts such as ecological integrity, ecosystem management, connectivity, buffer zones, or charismatic megafauna protection have been elaborated in the recent years to reach this goal. The American black bear is a good model to evaluate the efficiency of these conservation strategies since many factors can affect the demography of this species, such as hunting and trapping, habitat loss, and forest exploitation. The central question of my thesis is then the following: “Can a protected area such as La Mauricie National Park of Canada be able to maintain ecological integrity of a large mammal such as the American black bear?”. I used data from the long-term (1990-2005) monitoring of the black bear population in La Mauricie National Park of Canada. In the first chapter, I evaluated the influence of hunting and trapping in the periphery of the park, as well as the influence of poaching and nuisance kills on the survival of bears. Main results indicated that human-caused mortalities have a significant effect on this bear population. In the second chapter, I undertook a population viability analysis. The growth rates estimated with survival and reproduction data indicated that the number of females appears stable in the population, but that the number of males would decline if the population became isolated. In the third chapter, I emphasized the importance of accounting for sampling error in population viability analysis. Finally, in the fourth chapter, I determined the size of the greater ecosystem of La Mauricie National Park of Canada, based on the study of the movements of bears. The results of this thesis show the importance of the territory located outside of a protected area. In my opinion, we will not be able to achieve the long-term protection of the integrity of a bear population in a park of the size of La Mauricie National Park of Canada as long as conservation objectives, supported by the establishment of buffer zones around protected areas, are not integrated in a large-scale greater ecosystem management plan.

Full textThis doctoral research encompasses the fields of Indigenous studies, legal anthropology and political ontology. Through an analysis of the elaboration of the Atikamekw Nehirowisiwok code of practices, this study examines the articulation and translation of Nehirowisiwok normative practices, processes and principles in a context of territorial negotiations and dialogue with state institutions. This research focuses on the phenomenon of legal pluralism – the empirical description and analysis of the processes of negotiations, translations and reformulations that often take place, in asymmetrical relationship, notably between indigenous normative orders and state law. Like other First Nations, the Atikamekw Nehirowisiwok have, over the past few decades, been involved in self-determination claims for the recognition of their rights, as well as their political and territorial management practices. Unlike other First Nations, however, such as the James Bay Cree (Eeyouch / Eenouch) or the Nisgaa' of the Canadian West Coast, the Atikamekw Nehirowisiwok have not so far signed any treaty, historical or modern, with the governments of Quebec and Canada. The Atikamekw Nehirowisiwok are fully aware of the risk involved in such negotiations and of using the political and legal systems of the State in order to have their right to self-determination recognized. They are also conscious of the unavoidable ontological and epistemological conflicts they face. However, in spite of these obstacles, they remain mobilized and engaged in these inevitable negotiations with state institutions. In this mobilization, the Atikamekw Nehirowisiwok remain hopeful that their own political visions, as well as their ways of being-in-the-world and aspirations will be recognized. These efforts articulate and exhibit what Blaser (2004) defines as indigenous “life projects”, based on specific relations to the land and non-human agencies, on memory, expectations and desires. These “life projects” are mobilized concretely in daily practices, relationships to family territories, hunting activities and through the various mobilizations enacted by the Atikamekw Nehirowisiwok around the recognition of their rights.
