The Yellowknife greenstone belt has produced approximately 14 million ounces of gold, 13 of which came from the well explored southern half of the belt. The northern half of the belt, where the Discovery Property (1 million ounce past producer) is located, is not as well explored, but geologically very similar to the gold producing southern half. Gold on the Discovery Property, Northwest Territories, has been historically mined from a quartz vein formed adjacent to Archean metabasaltic bodies enclosed in metasedimentary rocks. Some of the metasedimentary rocks are correlated to the Archean Banting Group, based on a U-Pb age of 2.66 Ga on zircon (SHRIMP-RG). The metabasalt is correlated to the Banting Group based on its deposition relationship with the adjacent metasedimentary rocks. The Banting Group is present in the Yellowknife greenstone belt, located near the well-known Con and Giant Mines near Yellowknife, 90 km to the south. The two gold deposits forming the Discovery Property contains almost 2 million ounces in past production and current resources. The historical Discovery Mine was developed in quartz veins hosted in the metasedimentary rocks folded around the northern tip of one of the metabasalt bodies. In contrast, the newly defined Ormsby Zone consists of gold in silicified and sulphidized domains within metamorphosed pillowed and brecciated mafic volcanic rocks, and shares many characteristics with other Archean Orogenic gold deposits. Pyrrhotite ± arsenopyrite is directly correlated with the gold-bearing zones. Gold is also associated with pyrite and retrograde phases of chlorite, sericite and carbonate. Through detailed outcrop mapping and petrography the history of structural and metamorphic events are sequenced and the relative time of gold mineralization placed into the geological framework. Peak-metamorphic mineral assemblages on the property record upper greenschist to amphibolite facies conditions. Rocks on the Discovery Property have undergone at least four foliation-forming, deformational events. Three generations of folding are described, as well as a vertical lineation across the property. Gold mineralization occurred post-ductile fabric forming deformation, post-peak metamorphism, and syn-retrograde metamorphism. Although no visible evidence was observed mapping, metamorphic data present the possibility of a regional scale fault separating two metamorphic domains on the property.

Zhengguan yujing jiang 《貞觀玉鏡將》, a book compiled in Western Xia characters during the reign of Zhao Qianshun趙乾順 (嵬名乾順, r. 1086-1139) in the early 12thcentury on the art of military strategy and tactics, was discovered by a Russian in 1908. This provides scholars a valuable original source to carry out in-depth study on the military confrontation between Western Xia and the Northern Song Dynasty. Since the establishment of the Western Xia, there were long lasting internal disputes on their policies towards the Northern Song Dynasty. War or peace not only determined by their military power, their outcomes of political and economic reforms also played important roles. Different kinds of military strategy and tactics had been attempted but not much success had been secured. Zhengguan yujing jiang will be used as the primary resource in this thesis in order to find out the picture behind the screen. Special attentions will be focus on the modification and improvement of military system, military law and military strategy. / published_or_final_version / Chinese Historical Studies / Master / Master of Arts

Research was conducted to better understand the food insecurity (FI) experience among women in a small indigenous Canadian Arctic community. A descriptive, cross-sectional study was conducted in January-February 2006 with 54 women (20-40 years). Interviews were conducted on food insecurity, lifestyle, health, dietary self-efficacy and traditional food (TF) frequency; anthropometry data were also gathered. FI affected 55% of participating households in the community. Issues of food availability, quality and variety; lack of consumer skills; and lack of TF access were recognized as potential barriers to food security. Women from FI households were more likely to report an inability to access TF (p=0.0171). No associations were found between food security status and dietary self-efficacy or TF frequency of use. Current measures, programs and policies addressing FI need to consider unique barriers facing Indigenous Peoples living in northern Canada, including the barriers that affect access to TF resources.

This thesis examines soapstone carving among Inuit in Lake Harbour, NWT, as a socially adapted form of employment. A time allocation diary, participant observation and informal interviews were implemented. The empirical evidence reveals two important aspects of soapstone carving. First, carving acts as an important source of income for the mostly part-time carvers and their families in Lake Harbour. As such, carving functions as part of a household economic strategy that serves to capitalize the harvest of country food. Second, it notes that Inuit often produce carvings collectively, usually with the help of family members. Also, the returns from the carvings are shared not only among those who participate in the production of the sculpture, but among members of the extended family as a whole, following the patterns of kinship-based food-sharing. Thus, not only is carving an important supplement to other forms of income, it is an integral part of the existing social forms of Inuit society, most notably generalized reciprocity.

Fish resources of the Northwest Territories are receiving increased pressure by sports and commercial fisheries. This pressure is a result of northern resource development and an expanding tourist industry. The Fisheries Service of the Federal Department of Environment formed a Fisheries Management Division in 1971 to manage existing and proposed fisheries on a sustained yield basis. This study deals with compiling an inventory and assessment method to evaluate the fisheries potential of the Northwest Territories for the purpose of fisheries management. The method is based on an ecological framework and a classification of factors required for the fisheries management decision and the effective utilization of fish resources. Trends in transportation and fisheries organization were discussed for determining areas where fishing industries may potentially develop. Three time scales to area development potential in the Northwest Territories are used as priorities for field application of the method.
