The giant Kidd Creek Mine is an Archean Cu-Zn-Ag deposit in the Abitibi Greenstone belt, located in the Superior Province of Canada and is one of the largest known base metal massive sulfide mines in the world with a tonnage of 170.7 Mt (Past production, Resource and Reserve). The massive sulfides in Mine D comprise a number of ore lenses that are interpreted to be the downplunge continuation of the Central orebody from the upper mine. These are referred to as the West, Main, and South lenses. The massive sulfides overlie a silicified rhyolitic unit at the top of a mixed assemblage of rhyolite flows, volcaniclastic sediments and ultramafic flows. The sheared nature of the fragmental units in the hanging wall of the deposit, at depth, illustrates the greater deformation that has occurred than in the upper mine. Metal zonation and the distribution of Cu stringer mineralization suggest that the West and Main lenses may be part of a single massive sulfide body (Main orebody) that has been structurally dismembered. The South Lens is a detached body, separated by late faults. The large Cu stringer zone beneath the West and Main lenses has a thickness of up to 150 metres, and is much broader and structurally remobilized in Mine D partially due to a newly identified series of vertically trending offset faults, that extends along the entire length of the massive sulfide bodies. A number of features of the North, Central and South orebodies in the upper part of the mine (e.g., Se-rich halo around Cu-rich zones) have been recognized in Mine D and provide an important framework for correlating the deep orebodies with the upper levels of the mine. Drilling below the current mine levels indicates that the massive sulfide and Cu stringer zones continue below 10,200 feet (3109 m) and highlight the remarkable continuity of the deposit downplunge with no end in sight. Two main ore suites have been recognized in the upper part of the mine and in Mine D: a low-temperature, polymetallic assemblage of Zn, Ag, Pb, Cd, Sn, Sb, As, Hg, ±Tl, ±W, and a higher-temperature suite of Cu, Co, As, Bi, Se, In, ±Ni. More than 25 different ore minerals and ore-related gangue minerals are present, including Co-As-sulfides, Cu-Sn-sulfides, Ag-minerals, and selenides. The massive ores consist mainly of pyrite, pyrrhotite, sphalerite, magnetite and chalcopyrite, together with minor galena, tetrahedrite, arsenopyrite, and native silver with a quartz and siderite gangue. Despite the high Ag content of the ores, the majority of the massive sulfides are remarkably Au poor except for a local gold zone that has been recognized in the deep mine in association with high-temperature mineralization. The trace elements in the ores exhibit strong zonation and diverse mineralogy. Spectacular albite porphyroblasts, up to 1 cm in size occur in the most Cu-rich ores of Mine D which are coincident with the peak of regional metamorphism and likely represent higher metamorphic or hydrothermal temperatures. Overall the orebodies have remained remarkably similar downplunge. However, unlike the upper part of the mine, pyrrhotite is dominantly hexagonal, only tetrahedrite was observed as the dominant sulfosalt, and magnetite occurs as both blebby porphyroblasts and as abundant intergrowths with sphalerite-chalcopyrite ores and siderite. These characteristics suggest that the deep mine has been subjected to higher metamorphic temperatures, possibly related to depth of burial, and that the original hydrothermal fluids may of had a lower H2S/CO2 and/or higher temperatures.

Nors yra žinoma, kad pacientams, kuriems neseniai atliktos eritrocitų transfuzijos, kraujo grupių nustatymo hemagliutinacijos reakcija rezultatai gali būti nepatikimi dėl kraujyje cirkuliuojančių donoro ertrocitų, tačiau literatūroje nėra aiškių rekomendacijų, kuriais atvejais reikėtų naudoti molekulinius tyrimo metodus. Serologinis Duffy ir Kidd sistemų antigenų ir antikūnų prieš juos nustatymas – viena svarbiausių imunohematologinių problemų transfuzinėje medicinoje. Šiame darbe pirmą kartą Lietuvoje atlikti moksliniai tyrimai imunohematologijos srityje ir panaudoti genetiniai Duffy ir Kidd antigenų sistemų tyrimo metodai. Siekiant įvertinti Duffy ir Kidd antigenų sistemų fenotipavimo ir genotipavimo reikšmę, mes nagrinėjome klinikinių, demografinių, imunohematologinių bei su transfuzija susijusių veiksnių įtaką tyrimų rezultatams. Mūsų tyrimo metu nustatytas didesnis nei 30 proc. nesutapimų dažnis tarp Duffy ir Kidd antigenų sistemų fenotipavimo ir genotipavimo rezultatų patvirtino genetinių tyrimų naudą, atliekant dažnas eritrocitų transfuzijas. Atliekant šį darbą, pirmą kartą Lietuvoje nustatytas Duffy ir Kidd antigenų sistemų fenotipų paplitimas. Nustatytas laiko tarpas, per kurį įprastai klinikinėje praktikoje naudojamų serologinių tyrimų (hemagliutinacijos reakcijos) rezultatai gali būti patikimi, bei pateiktos atitinkamos rekomendacijos didina šio tyrimo praktinę vertę ir yra novatoriška šiuolaikinėje transfuzinėje medicinoje. / Accurate phenotyping of multitransfused patients is often complicated - mostly due to the presence of circulating transfused donor’s RBCs in the recipient’s blood, leading to discrepancies in the assessment of test results. The question when genotyping including Duffy and Kidd systems should be used for patients undergoing chronic RBC transfusions is still being discussed. Serological testing and evaluation of the antigens and antibodies of Duffy and Kidd systems are among the main problems in multitransfused patients. The research on immunohematology and blood group genetics has been caried out for the first time in Lithuania. A high rate (more than 30%) of disagreements between the results of phenotyping and genotyping in our study demonstrates the benefit of DNA-based testing for chronically-transfused patients. In order to estimate the value of phenotyping and genotyping of Duffy and Kidd antigen systems in patients undergoing long-term RBC transfusions, the impact of demographic, clinical, immunohaematological or transfusion-related factors, on the discrepancy of the results, was investigated. Time frame that could be appropriate to obtain reliable results of conventionaly used serologic tests (hemmagglutination reaction) after the last transfusion was established as well as appropriate recommendations were made. We believe that these studies could be helpful for clinical practice as well as in decreasing the risk of transfusion of red blood cells.

<p> The Potterdoal volcanogenic massive sulphide deposit is hosted by a tholeiitic/komatiitic succession located in northern Munro Township, Ontario. An integrated surface and drill core study of this property was undertaken to document the three dimensional structure and stratigraphy of the deposit. Petrography focused on mineralogical changes associated with the hydrothermal alteration within specific units. Several geochemical methods were used to determine the effects of hydrothemal alteration (as quantified by elemental mobility) as well as source magma affinities and tectonic setting. Based on this information, a model for ore genesis was developed. </p> <p> The Potterdoal deposit is hosted by volcanic rock of an iron tholeiite affinity, emplaced within an ocean floor rifting environment. The chemistry of the tholeiites shows similarities to that of large deposits like Kidd Creek, but lacks the felsic component of bimodal volcanism. It is suggested that felsic volcanics are absent because the local crust did not achieve sufficient thickness to allow partial melting of lower crustal material. </p> <p> The deposit consists of a stockwork zone overlain by an extensive massive sulphide lens which lies along a scarp structure defmed in the paleosurface. Stockwork mineralization is narrowly confined to conduits within a fault breccia in the footwall Ore Flow. gabbro, and widens into an overlying tectonic breccia. Sulphide paragenesis appears to be controlled by the thermal solubilities ofthe sulphide minerals, and consists of pyrite, sphalerite, pyrrhotite and chalcopyrite in both stockworks and the massive sulphide lens. The lens occurs at the top of the tectonic breccia near the paleo-seawater interface, and formed by direct replacement of the tectonic breccia. The lens locally exhibits ore grade base metal values (i.e. combined Cu and Zn content of at least 3% ), and shows an upward and outward gradation from chalcopyrite to sphalerite-dominated ore. These features suggest that exhalation of the hydrothermal system was focused into local vent sites. </p> <p> Mass change associated with the hydrothermal alteration envelopes surrounding Ore Flow fault breccia conduits involve loss of Si, Ca, Na and Sr, and gain of Fe, Mg, K, Cu and Zn. These changes are attributed to fluid-rock reactions which are consistent with hydrothermal alteration associated with other VMS deposits, The genetic model suggested for the Potterdoal deposit involves a hydrothermal system driven by heat from the intrusion ofthe Munro-Warden Sill at a high stratigraphic level. The relatively small size of the deposit is probably due to the rapid cooling of the sill, which shortened the life-span of the hydrothermal system. The primary source of metals was the upper portion of the Munro-Warden Sill, as indicated by the high degree of pervasive hydrothermal alteration of this part of the gabbro. </p> <p> Drill core information has also revealed the importance of the Buster Fault in the construction of the currently exposed Potterdoal stratigraphy. Thrusting subparallel to bedding along the Buster Fault during the Kenoran compressional event(~2.6 Ga) was responsible for the local repetition of tholeiitic flows, and has effectively removed the deep footwall rocks originally associated with the Potterdoal mineralization. </p> / Thesis / Master of Science (MSc)

Analyzing novels by Sheri Reynolds, Lee Smith, Barbara Kingsolver, Alice Walker, Gloria Naylor, and Sue Monk Kidd, I argue that these authors challenge religious structures by dramatizing the struggle between love and resentment that brings many women to the point of crisis but also inspires imaginative and generative processes of appropriation and revision, emphasizing not destination but process. Employing first-person narration in coming-of-age stories, Smith, Reynolds, and Kingsolver highlight the various narratives that govern the experiences of children born into religious cultures, including narratives of sexual development, gender identity, and religious conversion, to portray the difficulty of articulating female experience within the limited lexicon of Christian fundamentalism. As they mature into adulthood, the girl characters in these novels break from tradition to develop new consciousness by altering and adapting religious language, understood as open and malleable rather than authoritative and fixed. Smith, Kidd, and Naylor incorporate the Virgin Mary and divine maternal figures from non-Christian traditions to restore the mother-daughter relationship that is eclipsed by the Father and Son in Christian tradition. Identifying the female body as a site of spiritual knowledge, these authors present a metaphorical return to the womb that empowers their characters to embrace divine maternal love that transgresses the masculine symbolic order, displacing (but not necessarily destroying) the authority of God the Father and His human representatives. Reynolds and Walker portray physical pain, central to the Christian image of crucifixion, as destroying the ability of women to speak, denying them subjectivity. Through transgressive sexual relationships infused with religious significance, these authors disrupt the Christian moral paradigm by presenting bodily pleasure as an alternative to the Christian valorization of sacrifice. The replacement of pain with pleasure inspires imaginative work that makes private spirituality shareable through artistic creation. The novels I study present themes that also concern Christian and non-Christian feminist theologians: the development of feminine images of the divine, emphasis on immanence over transcendence, the apprehension of the divine in nature, and the necessity of challenging the reification of religious images and dualisms that undermine female subjectivity. I show the reciprocal relationship between fiction and theology, as theologians treat women's literature as sacred texts and fiction writers give life to abstract religious concepts through narrative.

Sue Monk Kidd’s The Secret Life of Bees (2002) tells the story of a motherless fourteen-year-old Lily Owens, raised by a cruel father, who desperately searches for clues to unlock her mother’s past. Kidd’s bildungsroman reveals the incredible power of black women, particularly a group of beekeeping sisters and a black Mary, to create a safe haven where Lily can examine her fragmented life and develop psychologically, finally becoming a self-actualized young lady. Lily’s matriarchal world of influence both compares and contrasts with the patriarchal world represented in Mark Twain’s Adventures of Huckleberry Finn, exposing the matriarchy’s aptly structured ways of providing a more healing environment than is Huck Finn’s. Kidd’s novel also showcases the stylistic strategies of first person narrative point of view, language, dialect, and the motif of place in order to contextualize the social awareness and psychological development Lily gains through her journey.

The state often enacts violence against marginalized groups by rendering them monstrous. The early eighteenth century saw early and stellar instances of this phenomenon in the way the British Empire pursued and executed pirates. These "golden age" pirates represented an extraordinary cross-section of marginalization politically, economically, socially, and otherwise, all of which threatened the political and social mores of Imperial Britain. In order to implement a policy and practice of pirate annihilation, British authorities constructed pirates as monstrous by racializing, dehumanizing, and emphasizing the supernatural quality of pirates. This study analyzes three eighteenth-century piracy trial transcripts--those of William Kidd, Stede Bonnet, and William Fly--in order to assess how lawyers and judges constructed pirates as monstrous so as to justify the massive and total violence inflicted on them as a class resulting in their complete destruction. In so doing, this study tracks rhetorical tactics and strategies still used by empires and the state today against marginalized peoples to an original historical source.
