Quartz-diorite Offset dykes from the 1850 Ma Sudbury Impact Structure stem from the Sudbury Igneous Complex (SIC) and extend into the footwall rocks in radial and concentric patterns with respect to the SIC. The dykes formed by emplacement of magma derived from the impact melt body into radial and concentric fractures generated in the country rock by the hypervelocity meteorite impact. The NE-striking Whistle Offset dyke extends from the northeast corner of the SIC, and is connected to the SIC by the Whistle embayment structure. A suite of oriented specimens was collected from 20 sites in the Whistle Offset dyke and the embayment, in order to determine the emplacement flow pattern within the dyke, the embayment, and the hosted massive sulfide deposits. The emplacement flow pattern was studied by using magnetic anisotropy measurements in order to infer the petrofabrics, and the subfabrics, defined by different mineral populations. The magnetic anisotropy methods included the anisotropy of magnetic susceptibility (AMS), the anisotropy of anhysteretic remanence (AAR) and the anisotropy of partial anhysteretic remanence (ApAR). The complex magnetic mineralogy of the sample suite was examined using measurements of partial anhysteretic remanence (PAR) acquisition, alternating-field demagnetization and thermal demagnetization, in addition to petrographic and scanning electron microscope (SEM) studies. The subfabrics which are interpreted to record the flow pattern in the Whistle Offset dyke, are defined by low coercivity coarse-grained magnetite, interpreted to be of primary igneous origin. The fabrics are suggestive of lateral (horizontal) injection of the magma and subsequent sinking of molten massive sulfide bodies through the still unsolidified dyke. Sinking of the massive sulfides is recorded by moderately plunging to vertical magnetic lineations. Steeply plunging lineations elsewhere in the Offset dykes may also indicate the presence of sunken massive sulfides in the subsurface.

To examine bat - habitat relationships, ultrasonic detectors were used to sample bat activity among: old-growth white pine (Pinus strobus ), mature white pine, boreal mixedwood, and selectively-cut white pine stands in central Ontario. Within the stands, bats were sampled in the canopy, the understory layer, and within canopy gaps. Forest structure was measured within each of the stands. The activity of bats was compared among forest stand types, within the stands, and in relation to forest structure. Also, maintaining forest wildlife populations requires data on the use of snags (i.e. dead trees). To provide further resolution of the habitat requirements of forest-dwelling bats, radio telemetry and exit counts were used to investigate the roosting ecology of mouse-eared bats (Myotis lucifugus and M. septentrionalis). Characteristics of snags used by mouse-eared bats were compared with randomly located snags and random geographic points, at three spatial scales (focal tree, surrounding forest, and landscape).

This qualitative study examines sixteen women's understanding of their experiences in community organizing in a northern urban context. While most front-line community organizing is done by women, there is a paucity of research giving voice to their particular realities. Similarly, there is little information describing community organizing in a northern urban context. The study's conceptual frameworks draw on theory and research from rural and northern social work, activist mothering, feminist social policy, diversity and exclusion, and the social construction of identities. It follows a feminist research paradigm. The study illustrates women community organizers' sense of place and their perceptions of the politics of language, cultural and linguistic tensions, and the influences of northern economic and geographic realities. The research findings demonstrate the processes of community organizing in a northern setting, community organizers' demoralization because of increasingly less generous social policy environments, and the challenges of racial and linguistic divisions in community organizing. The study challenges the urban lens dominating social work education and highlights the legitimacy of community organizing within social work education. It discusses future research possibilities for cross-cultural community organizing involving minority francophone and ethnocultural populations as well as the relativity of notions of oppression within francophone spheres.

The Morrison deposit, located at the Levack mine in the City of Greater Sudbury, is a footwall-type Cu-Ni-platinum-group-element (PGE) deposit hosted within a zone of Sudbury Breccia in the Archean Levack Gneiss Complex beneath the North Range of the Sudbury Igneous Complex. It consists of sharp-walled, sulfide-rich veins that are enriched in Cu-Pt-Pd-Au relative to contact-type mineralization and can be subdivided based on vein geochemistry, mineralogy, texture, and morphology into a pyrrhotite-rich upper domain, a chalcopyrite-rich lower domain, and a pyrrhotite equal to chalcopyrite middle domain. All domains contain steeply to vertically dipping first-order sulfide veins, irregular and discontinuous second-order sulfide veins, and disseminated sulfides in country rocks. First- and second-order veins can be further subdivided into inclusion-free veins typically within Sudbury breccia matrix or along clast-matrix boundaries, and very irregular and inclusion-rich veins associated with leucosomes in mafic gneiss clasts and granophyric-textured dikes. First-order veins consist of pyrrhotite > chalcopyrite = pentlandite > magnetite in the upper domain, pyrrhotite = chalcopyrite > pentlandite > cubanite > magnetite in the middle domain, and chalcopyrite >> pentlandite > pyrrhotite = cubanite > magnetite in the lower domain. Second-order veins consist of pyrrhotite = chalcopyrite > pentlandite > magnetite and chalcopyrite = millerite = pentlandite in the middle domain, and chalcopyrite >> millerite, millerite > chalcopyrite, bornite >> chalcopyrite, and millerite > bornite > chalcopyrite in the lower domain. Second order veins are adjacent to and in contact with epidote, amphibole, chlorite, carbonate, quartz, and magnetite alteration minerals. Sulfide mineralization in the Morrison deposit is similar to other footwall mineralization associated with the SIC. The veins appear to have been emplaced preferentially into zones of Sudbury Breccia that were within ~400m of the basal contact of the SIC, because that lithology is more permeable and because those zones are within the thermal aureole of the cooling SIC permitting penetration of sulfide melts. The mineralogical, textural, and geochemical zoning in the chalcopyrite-pentlandite-pyrrhotite-rich parts of the Morrison deposit are best explained by partial fractional and/or equilibrium crystallization of MSS and ISS. Bornite ± millerite-rich mineralization are interpreted to have formed by reaction of residual sulfide melts with wall rocks, consuming Fe and S to form actinolitemagnetite- epidote-chlorite-sulfide reaction zones and driving the sulfide melt across the thermal divide in that part of the Fe-Cu-Ni-S system to crystallize borniteSS ± milleriteSS. Gold-Pt-Pd appear to have been more mobile than other metals, forming localized zones of enrichment, although it is not clear yet whether they were mobile as Au-Pt-Pd-Bi-Te-Sb-rich melts or aqueous fluids.

This thesis presents results from the through-going muon analysis at the Sudbury Neutrino Observatory. Over 1229.26 days, 77376 direct cosmic ray muons above cosθ > 0.4 and 514 neutrino-induced muons in the range -1 < cosθ < 0.4 were detected. A log-likelihood analysis was performed on the neutrino-induced muons to produce a flux measurement and constrain atmospheric neutrino mixing parameters. The best-fit oscillation values were Δm² = (2.6±2.0) × 10⁻³ eV², sin²2θ = 1.0±0.1. The observed muon flux was found to be (2.48±0.25) × 10⁻¹³ cm⁻²s⁻¹sr⁻¹ resulting in an overall flux normalization 1.22±0.09 times the theoretical estimates from the Bartol group. The quoted uncertainties are 1-D marginalized. The no-oscillation hypothesis was ruled out at 99.8% confidence level. The observed number of direct cosmic ray muons was converted into a vertical depth intensity. The resulting fits to the intensity as a function of depth were I₀ = (0.93±0.05) × 10⁻⁶ cm⁻²s⁻¹sr⁻¹, x = 2.33±0.31 km.w.e. and α = 5.62±0.40.

The Sudbury Neutrino Observatory (SNO), a heavy water Cherenkov experiment, was designed to detect solar Boron-8 neutrinos via their elastic scattering interactions on electrons, or charged current and neutral current (NC) interactions on deuterium. In the third phase of SNO, an array of Helium-3 proportional counters was deployed to detect neutrons produced in NC interactions. A simulation of the current pulses and energy spectra of the main kinds of ionization events inside these Neutral Current Detectors (NCDs) was developed. To achieve this, electron drift times in NCDs were evaluated with a Monte Carlo method, and constrained by using wire alpha activity inside the counters. The pulse calculation algorithm applies to any ionization event, and takes into account processes such as straggling, electron diffusion, and propagation through the NCD hardware. A space charge model was developed to fully explain the energy spectra of neutron and alpha events. Comparisons with data allowed the various classes of alpha backgrounds to be identified, and gave evidence for the spatial non-uniformity of Uranium-238 and Thorium-232 chain nuclei in the counter walls. The simulation was applied to determine the fractional contents of the main types of alpha backgrounds in each NCD string. The number of neutron capture events in the array was extracted via a statistical separation, using Monte Carlo generated alpha background pulse shape parameter distributions and minimal energy information. The inferred total Boron-8 solar neutrino flux is: φ_NC< = 5.74 ± 0.77 (stat) ± 0.39 (sys) x 10⁶ cm^-2s^-1 in agreement with Standard Solar predictions and previous SNO results.

The Sudbury Structure, Ontario, is the remnant of a 1.85 Ga old impact crater, 200--250 km in diameter. Erosion and tectonism have affected the Sudbury Structure and resulted in considerable brittle and ductile deformation, and the removal of the surface expression of the crater structure and all exterior deposits typical of many terrestrial impact structures. However, substantial amounts of the interior deposits, including the craterfill products, have been preserved within the Sudbury Basin. Although most workers acknowledge an impact origin for the Sudbury Structure, the origin of the Sudbury Igneous Complex (SIC), located inside the Sudbury Structure, remains controversial. The objectives of this study are to elucidate the division of the SIC into lithologically separate phases and to understand their relation to impact and endogenic igneous processes by using physical, chemical and computer methods, and to model the genesis of the SIC. The SIC is a 2.5--3.0 km thick, ∼60 x 27 km elliptical igneous-rock body, consisting of four major lithologies (top to base): granophyre, quartz gabbro, norite, and the so-called contact sublayer. All these lithologies are continuous across the complex, except for the contact sublayer. Modal compositions reveal that the current nomenclature is improper. According to the IUGS classification, "quartz gabbro" samples should be classified as quartz monzogabbros and "norite" samples as quartz gabbros or quartz monzogabbros. In view of these observations, an updated terminology is proposed (top to base): upper unit, transition zone, middle unit, lower unit, and contact sublayer. Gradational mineralogical and geochemical variations between the SIC lithological units are evidence of a single melt system for the SIC. The occurrence of primary hydrous minerals, deuteric alteration, and abundant micrographic and granophyric intergrowths demonstrate that this melt was rich in H 2O. The intergrowths and other far-from-equilibrium textures are likely due to rapid crystallization as a result of a large undercooling caused by the exsolution of a volatile phase. The SIC differs from other known terrestrial impact melt sheets only by its great thickness and its chemical layering. It is concluded that the SIC is a differentiated impact melt sheet, the only one identified on Earth to date.

The Garson Ni-Cu-PGE deposit is located on the South Range of the 1850 Ma Sudbury structure along the contact between the Sudbury Igneous Complex (SIC) and the underlying metasedimentary and metavolcanic rocks of the Paleoproterozoic Huronian Supergroup. It comprises four ore bodies that are hosted by E-W-trending shear zones that dip steeply to the south. The shear zones formed as south-directed D1 thrusts in response to flexural-slip during regional buckling of the SIC. They imbricated the ore zones, the SIC norite, the underlying Huronian rocks and they emplaced slivers of Huronian rocks and anatectic breccia into the overlying Main Mass norite. Coexisting garnet-amphibole pairs yielded syn-D1 amphibolite facies metamorphic temperatures ranging from ~550°C to 590°C. The shear zones were coeval with the moderately southdipping South Range and Thayer Lindsley shear zones, which formed to accommodate the strain in the hinge zone as the SIC tightened with progressive D1 shortening. The SE limb of the SIC was overturned together with the D1 thrusts, which were then reactivated as steeply south-dipping reverse shear zones during syn-D2 greenschist metamorphism.Syn-D2 metamorphic titanite yield a U-Pb age of ca. 1849 ± 6 Ma, suggesting that D1 and D2 are part of a single progressive deformation event that occurred immediately after crystallization of the SIC during the Penokean Orogeny. The ore bodies plunge steeply to the south parallel to the colinear L1 and L2 stretching mineral lineations. Ore types consist mainly of pyrrhotite-pentlandite-chalcopyrite breccia ores, but also include pyrrhotite-pentlandite-chalcopyrite disseminated sulfide mineralization in norite, and syn-D2 quartz-calcite-chalcopyrite-pyrrhotite-pentlandite iv veins. In the breccia ores, matrix sulfides surround silicate rock fragments that have a strong shape-preferred orientation defining a pervasive foliation. The fragments are highly stretched parallel to the mineral lineations in wall rocks, suggesting that the ore bodies are zones of high strain. Pyrrhotite and chalcopyrite occur in piercement structures, in boudin necks between fragments, in fractures in wall rocks and in fold hinges, suggesting that the sulfides were mobilized by ductile plastic flow. Despite evidence of high strain in the ore zones, the sulfide matrix in D1 and D2 breccia ores show little evidence of strain as they consist predominantly of polygonal pyrrhotite aggregates, suggesting that they recrystallized during, or immediately after D1 and D2. However, rare elongate pyrrhotite grains aligned parallel to S2 are locally preserved only in D2 breccia ores. Exsolution of pentlandite loops along grain boundaries of elongate pyrrhotite formed S2-parallel pentlandite-rich layers in D2 breccia ores, whereas the pentlandite loops are multi-oriented in D1 contact breccia as they were exsolved along grain boundaries polygonal pyrrhotite. Because exsolution of pentlandite post-date D1 and D2, and that individual pentlandite grains neither have a shape-preferred orientation nor show evidence for cataclastic flow, the sulfides reverted to, and were mobilized as a homogeneous metamorphic monosulfide solid solution (mss) during D1 and possibly D2. This is in agreement with predictions from phase equilibria as the average Garson composition plots within the mss field in Fe-Ni-S ternary diagram at temperatures above ~400°C. Disseminated and breccia ores at Garson have similar mantle-normalized multi-element chalcophile patterns as undeformed contact-type disseminated and massive ore, v respectively, at the well known Creighton mine in the South Range. This suggests that the Garson ores are magmatic in origin and that their compositions were not significantly altered by hydrothermal fluids and deformation. The lack of variations in Ni tenors between the disseminated and breccias ores suggest that the R-factor was not the process controlling metal tenors because the disseminated sulfides do not consistently have higher metal tenors than the breccia ore. The breccia ores are enriched in Rh-Ru-Ir and are depleted in Cu-Pd-Pt-Au, in contrast to footwall-type ore at the nearby Garson Ramp mine which is enriched in the same metals. When Ni100, Rh100, Ir100, Pt100 and Pd100 are plotted against Cu100, the breccia and footwall-type ore analyses plot along model mss fractionation and sulfide melt model curves, suggesting that these two ore types are related by mss fractionation. In summary, the Garson breccia ores are mss cumulates that settled quickly at the base of the SIC via a gravity filtration process, and were mobilized as a metamorphic mss by ductile plastic flow during D1 and D2. Despite minor local hydrothermal mobilization of some metals, the study confirms findings from other studies that highly deformed Ni-Cu-PGE deposits, such as the Garson deposit, can provide important information on the genesis of the deposits.

Sudbury serves as a relevant historical case study of a settlement that has undergone several transformations since its inception as a fledgling village in the latter part of the nineteenth century. Though changes of this kind have been frequent in Ontario, they have not normally happened to hinterland resource communities. This article suggests that Sudbury is unique in this regard, having evolved through five distinct stages: (I) a railway company village, (2) a colonial-frontier mining town and city, (3) a regional central-place, (4) a declining metropolis, and (5) a nearly selfsustaining community. The constant restructuring of Sudbury's society and economic base has been caused by a variety of external and internal forces, among which the "human dynamic" has been vital and ever present. The paper suggests that under certain circumstances a resource community can progress from a staples and boom-bust existence to a more sustainable urban economy based on local and regional influences.

Over a century of mining activities and smelting in the area of Sudbury, Ontario, Canada have resulted in the contamination of the local soils with metal(loid) bearing particulates. Minor and trace elements associated with these phases are released during their weathering. This release is therefore strongly dependent on the mineralogical and chemical character of the metal(loid) bearing phases. The metal(loid)s are then subject to transport before being attenuated through their incorporation into secondary phases. Elevated concentrations of metal(loid)s in silica rich alteration layers has recently been described for altered surfaces at the solid-water and solid-atmospheric interfaces in tailings, and in the vicinity of smelters, respectively. To determine if similar coatings occur in soils, samples were taken from areas around three major smelting centers in the area. Coated grains were extracted from these samples and individually mounted to be analysed. Particulate matter (representing primary metal(loid)-bearing phases) and coatings (secondary metal(loid)-bearing phases) were analysed using scanning electron microscopy, Raman spectroscopy, Laser-Ablation Inductively-coupled plasma mass spectroscopy, Micro-X-ray fluorescence, and X-ray photoelectron spectroscopy. The particulates were divided into three main groups: smelter-derived particles, sulfides, and nickel-oxides. Smelter derived particles contained the most elevated concentrations of metal(loid)s in their sulfide inclusions and metal(loid)-rich rims. The mobility of metal(loid)s in the identified mineral phases found within particulates mirrored the transport observed in the soil column; Zn>Cu>Ni>Pb. Once mobilized, these elements are subject to transport before being attenuated by secondary phases. Micro-coatings were found to be composed of hematite, schwertmannite, ferrihydrite, silica, and jarosite group minerals. Coatings are distinguished on the basis of their atomic Si:Fe ratios: FeOx coatings have Si:Fe <1, Si–FeOx coatings have Si:Fe between 1-10, and SiOx coatings iv have Si:Fe>10. Iron-rich coatings (FeOx) and silica-rich coatings (SiOx) have lower trace-metal concentrations than Fe-SiOx coatings. Micrometer-thick coatings are predominantly composed of hematite, schwertmannite, ferrihydrite and (amorphous) silica and contain elevated metal(loid) concentrations in the form of metal(loid)-rich phosphate minerals (mainly minerals of the jarosite group). A general model is developed that describes the formation of mineral coatings in acid soils and their important role in the uptake and retention of metal(loids). Here, micrometer-thick Fe-silica coatings form through adsorption, co-precipitation and dehydration processes involving amorphous silica and iron hydroxides. Metal(loid)-bearing phases nucleate within a gel-type matrix and are subsequently preserved during dehydration and solidification. Aluminum-rich surfaces form on mineral grains once the pH has been raised sufficiently high (pH~5-6) so as to lead to the complete removal of sulfate-bearing phases. The implications of this model are widespread in terms of the attenuation of metal(loid)s in acid soils and their retention or subsequent remobilization in recovered soils with near neutral pH.

Mise en discours d'identites minoritaires : les francoontariens de sudbury dans les annees soixante, l'identite canadienne francaise repliee sur la paroisse, la famille et la langue francaise, identite nationale qui trouvait sa cohesion au-dela des frontieres provinciales s'est fissuree. Face aux bouleversements socioeconomiques, a l'emancipation et a la revendication d'autonomie du quebec, la minorite franco-ontarienne a cherche de nouveaux reperes identitaires. La mobilisation politique, portee par les luttes scolaires particulierement - gestion des ecoles secondaires par les francophones eux-memes, par exemple-, la resistance a la domination de l'anglais et la revendication pour l'obtention d'un systeme institutionnel unilingue a tente de definir une nouvelle facon d'etre francais en outario. Mais, aujourd'hui, face a l'effondrement du reve nhational, face a l'attrait du bilinguisme et de la politique qui le sous-tend, a-t-on pu echapper a une fragmentation des identites? de l'assimilation - culturelle ou linguistique - a l'opposition marquee par la revolte, cette etude, par une methode ethnomethodologique minutieuse, a determine les differents facteurs constitutifs des profits identitaires : et au-dela de la question des pratiques linguisituques et de l'engagement politique, la conscience ethnique s'actualise dans les predonnees identitaires et dans la force du sentiment d'appartenance : de l'histoire, a la relation avec la filiation, les identites se tissent, multiples et mouvantes, par une prise de conscience ethnique. Dans la confrontation a l'autre et a ceux de son propre groupe, les frontieres identitaires a l'interieur de la communaute franco-ontarienne ne sont pas closes et, d'un profit a l'autre, le glissement peut se faire, motive par des sentiments qui depassent le seul emploi et maintien de la langue
An expression of minority identities :franco-outarians from sudbury in the 1960s, the french-canadian identity, wich had been centred around the parish, the family and the french language and found a national cohesivencess, was split. Faced with socio-economic upheaval and quebec's striving for emancipation and autonomy, the franco-ontarian minority searched for new pegs on wich to hinge its identity. Political activism, fuelled mainly by struggles in the field of education - the fight for self-governance of french schools, for instance - resistance to english language predominance and advocacy for a unilingual institutional system made it possible for franco-ontarians to live their francophone identity in a new way. In today's context, however, a question arises : have franco-ontarians managed to avoid the splintering of their identity in the face of the collapse of the national dream and the seductivencess of bilingualism and its underlying politics? this research is a meticulous ethnomethodological survey of the various constituent factors that make up franco-ontarians identity profiles, from assimilation (both cultural and linguistic) to revolt. Beyond the issue of linguistic pratices and political advocacy, ethnic awareness becomes actualized through the franco-ontarian identity background and a strong sens of belonging. From history to filiation, identities are wowen, multiply and change, through awareness of their ethnicity. Through the confrontation of the other and other group memebers, identity boundarie s within the franco-ontarina community are not closed and leakage occurs amongst the various profiles, brought upon by fellings that go beyond simply using and maintaining a language

Metal-contamination of lakes simplifies food webs and reduces the efficiency of energy transfer to top trophic organisms, such as yellow perch (Perca flavescens). Benthic invertebrate community composition and yellow perch diet, growth and activity levels from lakes along a metal-contamination gradient were used to assess the importance of a naturally diverse prey base for maintaining energy transfer to growing fish, and how this is disrupted by metal-contamination. As perch grow larger, they shift their diet to larger prey; otherwise, the activity costs of foraging for many, small prey, instead of a few large prey, become too high and the fish stop growing. Metal contaminated lakes have less diverse zoobenthic communities, particularly the lack of large bodied invertebrate taxa, forcing perch to rely on smaller benthic prey. Perch from metal-contaminated lakes display slow growth and poor condition during benthivory. Estimates of fish activity, using the activity of the glycolytic enzyme Lactate dehydrogenase in perch white muscle tissue as a proxy, suggest that diet shifts to larger prey lower activity costs and may explain how diet shifts maintain growth efficiency as perch grow larger. Perch from metal-contaminated lakes cannot benefit from the energetic advantages of switching to larger prey and thus exhibit poor growth.

The Sudbury Neutrino Observatory (SNO) was a 1 kilotonne heavy water Č{C}erenkov detector. Evidence for flavour changing neutrino oscillations was found by comparing the rate of Charged Current interactions with that of Neutral Current (NC) interactions. This thesis is concerned with the accurate determination of the NC flux in the Neutral Current Detector (NCD) phase of SNO. The measurement and understanding of radioactive backgrounds arising from decays of naturally occurring $^{232}$Th and $^{238}$U chain nuclei is crucial. This is because their daughter nuclei can produce neutrons via photodisintegration of deuterium. These would be indistinguishable from those produced by NC neutrino interactions. As the probability of neutron production was dependent upon the nature and location of activity, each contribution had to be determined separately. Of particular concern were $^{232}$Th and $^{238}$U in the D$_2$O and Neutral Current Detectors (NCDs). A maximum likelihood method was developed that exploited differences in the event isotropy and radial profile of each event class. These results were in agreement with water assay results and pre-deployment radioassays of the NCDs. An independent measurement of the $^{232}$Th content in the D$_2$O and H$_2$O was made by regularly assaying the water using filters loaded with hydrous titanium oxide. The concentration of $^{232}$Th in the water was determined by coincidence counting of the final assay sample. A new counter system was designed and built and the calibration and use of this system are presented. Two areas of increased activity were discovered on two of the NCDs deployed in the detector which would have prevented an accurate measurement of the NC flux. A method was devised to determine the composition and activity of one of these hotspots. The results were in good agreement with two independent methods and the uncertainty on the NC flux was reduced from $>7$% to $<1$%. The total number of neutrons produced per day by photodisintegration for $^{232}$Th and $^{238}$U in the D$_2$O and NCDs was measured to be $0.66^{+0.08}_{-0.07}$. This was significantly less than the expected 12.6 NC neutrino interactions per day. In the third phase, two independent data streams existed: PMT and NCD. A Monte Carlo study was undertaken to determine whether an accurate measure of the NC flux could be obtained using only PMT data. Results showed that no improvement could be made upon results from previous phases and the best measurement of the NC flux in the final phase would be made using PMT and NCD data.
