Master of Science / Department of Geology / Matthew E. Brueseke / Previous studies of the northern Great Basin have indicated that mid-Miocene epithermal gold and silver ore deposits distributed regionally are temporally related to the magmatic activity associated with the onset of widespread extension and the Yellowstone hotspot (Saunders and Crowe, 1996; Kamenov et al., 2007). This study is focused on the volcanic rocks and ore deposits from the Silver City district (SCD), ID to address the petrogenesis and magmatic evolution that was influential in forming local precious metal deposits. The goal is to understand the tectonomagmatic conditions that contributed to the petrogenesis of the volcanic suite in the Silver City district, which can be used to provide details on the relationship between coeval mid- Miocene magmatism and mineralization across the northern Great Basin and Oregon Plateau. In order to better constrain the magmatic evolution of the SCD and potential sources of the precious metals, we have undertaken detailed sampling of local crust and mid-Miocene volcanic units to constrain their physical, geochemical, isotopic, and geochronological characteristics, as well as provide constraints on the petrogenesis of the mid-Miocene volcanic package. Prior studies of the local volcanism have yielded K-Ar and [superscript]40Ar/[superscript]39Ar ages of ~16.6 to 14 Ma (Bonnichsen, 1983), while others have dated adularia from one SCD mineral vein and obtained [superscript]40Ar/[superscript]39Ar ages of between 15.6 and 16.3 Ma (Hames et al., 2009; and Aseto et al., 2011). Field observations are consistent with earlier work (Lindgren, 1900; Asher, 1968; Pansze, 1975; Halsor et al., 1988; Bonnichsen and Godchaux, 2006; Camp and Ross, 2009) and reveal a sequence of basalt consisting of regionally prevalent Steens Basalt that pre-dated precious metal mineralization. Some of the basalt appears to have been erupted locally, based on the presence of mafic dikes and thick pyroclastic deposits similar to other regional mid-Miocene magmatic systems. Stratigraphically overlying this lower basalt suite is a complex package of rhyolite flows and domes, thin silicic pyroclastic units, additional basaltic lava flows, intermediate lava flows, and mafic/silicic shallow intrusives. Geochemical analysis indicates that the basaltic and basaltic andesite lava flows are locally erupted flows of Steens Basalt while the intermediate and silicic volcanism in SCD can be classified into nine distinct units including two andesites, one dacite, four rhyolites and two rhyolite tuffaceous units. Geochemical modeling suggest that the intermediate and silicic magmas were formed by a combination of open system processes, including low pressure partial melting and assimilation of mid to upper crustal granitoid basement rock, and magma mixing between silicic and basaltic endmembers. The formation of silicic volcanism in the SCD is similar to other regional mid-Miocene silicic volcanic systems (e.g. Santa Rosa-Calico volcanic field and Jarbidge Rhyolite). Based on new [superscript]40Ar/[superscript]39Ar geochronology of both volcanic units and epithermally emplaced mineralization, SCD volcanism appears to have erupted over a relatively short amount of time that overlaps with local epithermal Au-Ag mineralization.

Estimating herbivore density is an important part of understanding their impact on vegetation.  Many studies have been carried out on the impact of reindeer and other herbivores on arctic and sub-arctic vegetation, but they are difficult to compare as they typically use different methods to estimate herbivore activities.  The aim of this study was to compare three methods that were based on the recent International Tundra Experiment herbivory protocol to measure the activities of three herbivore groups: reindeer, rodents and invertebrates. The robustness of the methods themselves was then evaluated.  Fieldwork was carried out at 12 sites in the Fennoscandian mountain area, with controls inside reindeer exclosures.  The results showed that the methods were the most robust when measuring reindeer activities.  The reindeer measurements were also well correlated with a reindeer-density estimate calculated from official reindeer population data.  This study recommends considering the use of photographs to increase the time-efficiency of pellet-counts.  The rodent activity estimates were good, but the patterns inside exclosures differed to the patterns outside exclosures.  The results for invertebrates were deemed to be less reliable as the measurements for one method were not recorded at an appropriate scale.  In conclusion, the findings of this study will help improve the comparability of future studies on the impact of reindeer herbivory and other herbivores, and gives suggestions for more accurate ways of measuring herbivore pressure in arctic and sub-arctic vegetation.

The goal of this thesis is to evaluate the current state of Bedřichov from the perspective of tourism and draw the attention to the threats and opportunities stemming from its potential further development. This thesis employs the Tourism Area Life Cycle (TALC) model, firstly applied to Bedřichov itself and later compared to Špindlerův Mlýn. This method allows for the analysis of the current position of Bedřichov in its life cycle as well as its expected development. The outcome of this thesis should be beneficial in the evaluation of further development in Bedřichov with respect to the ecological sustainability in the region.

This thesis deals with forms of aluminium occurring in acidified surface waters. Special attention is paid to inorganic monomeric aluminium, fraction, which has toxic effect on some species of aquatic and terrestrial biota. The thesis primarily focuses on the analysis of surface water, groundwater and soil water chemistry in the year-round and long-term monitoring. The practical took place on an experimental mountain basin Uhlířská, which is drained by river Černá Nisa. Uhlířská basin is located in the Jizera Mountains and represents the area which was significantly exposed to the acid atmospheric deposition in the second half of the 20th century. Long-term exposure to acid precipitation caused the acidification of soil and watercourses, forest degradation and deforestation of large parts of the basin. Decrease in pH and an increase in concentration of toxic aluminium also caused species depletion of aquatic ecosystems. Monomeric forms of aluminium were determined spectrophotometrically, the concentration of total aluminium was determined by the method of flame atomic absorption spectrometry (FAAS), in case of low concentration electrothermal atomic absorption spectrometry (ETAAS) was used. Five forms of aluminium were obtained - Altot, AlAS, Alm, Alo and potentially toxic Ali. Appart from...

Thus, in order to foster sustainability in these environments, it is suggested that for the proper management of agro-ecosystems in these areas, agroecological practices should be the technological basis, methodological, sociological and epistemological. Thus, it is considered of paramount importance to the highlander farmers to appropriate the notion of territory and knowledge and agro-ecological processes, so that they have autonomy in the search paths that enable better conditions of stay and practice of agriculture in the mountains. In this sense, the proposal is that local development is rooted in inbreeding in leadership, participation, conservation of natural resources and the socio-cultural heritage and the vitality of the political-institutional and economic relations. Thus, it is important to point out that the proper maintenance of the territory implies more balanced environments in product differentiation and appreciation of local culture. For all this, the thesis will seek to answer the following research problem: How endogenous territorial aspects related to family agroecological production, may enhance sustainable rural development processes in mountain environments? The purpose of it is to assess how spatial aspects related to family farming, can be valued in the creation of sustainable rural development processes in mountain environments, using this agroecology. Therefore, we conducted case studies in the Fazenda Rio Grande community in the municipality of Nova Friburgo (RJ), and the region of Alto Camaqu? (RS) to assess the perception of farmers about the territorial aspects. The results showed that some cultural aspects of farmers in Fazenda Rio Grande, Nova Friburgo has been lost over time, as the production of bread white corn meal, for example, but on the other hand, the community has organized for access to public policies and adoption of conservation tillage practices such as green manure and tillage. With regard to research carried out in the territory of the Alto Camaqu?, data analysis reveals a family livestock peasant-based, where the actors and subjects involved in Project Alto Camaqu? - aimed at enhancement of the site and its resources as strategies for access the different markets - handle the agricultural ecosystems in order to keep alive local traditions. Another aspect that should be considered in maintaining this modus operandi and conservation of natural resources, is given due to the isolation of farmers in this region, given the great distances that separate the properties and the territory in relation to urban areas, associated with not adopting of "technological packages" used in an industrial base of agriculture. / A tese parte do princ?pio que a cultura, o saber fazer, o modus vivendi, e o capital territorial, s?o aspectos fundamentais na diferencia??o de produtos e servi?os oferecidos por agricultores e pecuaristas que vivem e se (re)produzem em ambientes montanhosos. Assim, no sentido de fomentar a sustentabilidade nesses ambientes, sugere-se que para o manejo adequado dos agroecossistemas nessas ?reas, pr?ticas agroecol?gicas deve ser a base tecnol?gica, metodol?gica, sociol?gica e epistemol?gica. Sendo assim, considera-se de suma import?ncia que os agricultores montanheses se apropriem da no??o de territ?rio e dos conhecimentos e processos agroecol?gicos, de forma a que estes tenham autonomia na busca de caminhos que viabilizem melhores condi??es de perman?ncia e pr?tica da agricultura nas montanhas. Nesse sentido, a proposta ? que o desenvolvimento local esteja alicer?ado na endogenia, no protagonismo, na participa??o, na conserva??o dos recursos naturais e do patrim?nio sociocultural, bem como na vitalidade das rela??es pol?tico-institucionais e econ?micas. Assim, ? importante destacar que a correta manuten??o do territ?rio implica em ambientes mais equilibrados, na diferencia??o de produtos e valoriza??o da cultura local. Por tudo isto, a tese buscar? responder o seguinte problema de pesquisa: De que forma aspectos territoriais end?genos, relacionados ? produ??o agroecol?gica familiar, podem potencializar processos de desenvolvimento rural sustent?veis em ambientes de montanha? O objetivo da mesma ? avaliar de que forma aspectos territoriais, relacionados ? produ??o agr?cola familiar, podem ser valorizados na constitui??o de processos de desenvolvimento rural sustent?veis em ambientes de montanha, utilizando para isto a agroecologia. Para tanto foram realizados estudos de caso na comunidade da Fazenda Rio Grande, em Nova Friburgo (RJ), e na regi?o do Alto Camaqu? (RS), para avaliar a percep??o dos agricultores familiares acerca dos aspectos territoriais. Os resultados demonstraram que alguns aspectos culturais dos agricultores da Fazenda Rio Grande, Nova Friburgo tem se perdido com o tempo, como a produ??o da broa de fub? de milho branco, por exemplo, mas, por outro lado, a comunidade tem se organizado para o acesso a pol?ticas p?blicas e ado??o de pr?ticas conservacionistas do solo, como a aduba??o verde e o plantio direto. No que se refere ?s pesquisas realizadas no territ?rio do Alto Camaqu?, a an?lise dos dados revela uma pecu?ria familiar de base camponesa, onde os atores e sujeitos envolvidos no Projeto Alto Camaqu? ? que visa ? valoriza??o do local e de seus recursos como estrat?gias para acesso a mercados diferenciados - manejam os agroecossistemas de forma a manter viva as tradi??es locais. Outro aspecto que deve ser considerado na manuten??o desse modus operandi e na conserva??o dos recursos naturais, se d? em virtude do isolamento dos pecuaristas dessa regi?o, dado as grandes dist?ncias que separam as propriedades e o territ?rio em rela??o a ?rea urbana, associado a n?o ado??o de ?pacotes tecnol?gicos? utilizados em uma agricultura de base industrial.

This thesis investigated marine isotope stage {MIS) 3-2 glacial sequences in the South Fork Hoh River Valley, Washington and the Lake Hawea Valley, New Zealand. Research objectives were to reconstruct the style and timing of ice advance in both areas and to assess the viability of luminescence dating of glacial sediments in various depositional facies and distances from the ice front. This thesis focused on the sedimentology and stratigraphy of surficial and older glacial sequences in the South Fork Hoh and Lake Hawea areas and used OSL and radiocarbon dating techniques to establish age control for the deposits. Specifically, this research identified, described, and dated the stratigraphy of glacial sequences in order to reconstruct ice dynamics. This work also presents updated geomorphic maps for both study areas as an additional way to show ice advance and retreat events recorded in deposited sediment and geomorphic surfaces. The glacial sequence expressed in the Lake Hawea moraine exposure shows four distinct depositional events that represent retreat from an ice position down -valley, re-advance to the Hawea moraine position, and subsequent retreat and deglaciation broadly spanning -32-18 ka. These results document the terminal glacial advance and subsequent retreat in the Lake Hawea Valley and contribute to the wider swath of research studying the last phase of glacial retreat and its connections to climate on the South Island of New Zealand. The Hawea chronology corresponds to other glacial records and paleoclimate reconstructions from the South Island that collectively suggest the commencement of deglaciation at -13 ka. Three late Pleistocene ice positions are preserved in the South Fork Hoh River Valley, here referred to as South Fork 1-3 (SF 1-3). One of these positions has not previously been recognized in this valley or in the mainstem Hoh River Valley. Optically stimulated luminescence (OSL) and radiocarbon (14C) ages are generally consistent throughout the valley. These finding s advocate for a detailed sedimentologic and stratigraphic approach to glacial depos its and questions whether a similar advance or still -stand occurred in other valleys in the region. If so, this may reveal information regarding climate influences on MIS 2 glaciers in the Olympic Mountains. This research also assesses the applicability of OSL dating to glacial deposits in both field areas. Quartz OSL dating was used in the South Fork Hoh study area; however, quartz produced unreliable results in the Hawea study area, so samples were therefore assessed using feldspar methods. The results advocate for a facies-based sampling approach in glacial settings, where better sorted sandy facies and more distal deposits produce better bleached and more reliable age results than other deposits.

Dans les montagnes pluvieuses du Nord-est de la Turquie, l’on danse et l’on chante au son du kemençe, une petite vièle à trois cordes, parmi les vaches et les fusils. A partir d’une enquête dans ces montagnes, le propos de la thèse est d’appréhender un usage communal de la musique, soit une tradition musicale qui ne relèverait pas de ce que l’on entend communément par art - la création d’artistes, eux-mêmes figures marginales au sein de leur société - mais plus sûrement d’un bien communal, quelque chose dont l’usage est donné à tous (au sein de la communauté) et la propriété à personne (en tant qu’individu). Depuis ce constat d’un communal, l’enjeu sera également de comprendre les logiques de folklorisation et de commercialisation qui travaillent les musiques turques depuis maintenant un siècle. / In the rainy Pontic mountains (Northeast of Turkey) people sing and dance at the sound of the kemençe, a tiny three stringed fiddle. Through fieldwork in those mountains, the purpose of this dissertation will be to describe what would be called a “communal use” of music: a musical tradition not understood as art (the creation of artists) but as a common within a certain community. From this observation, the goal will also be to understand the logics of folklorisation and commercialization at work in Turkish music since a century.

The original purpose of this study was a detailed structural analysis of the Jurassic Otter Point Formation in order to determine if the Canyonville Fault Zone, which forms the northern boundary of the Klamath Mountains in the Riddle - Canyonville area (Benson and Perttu, 1980), extends westward to the coast and, if possible, to characterize the structure of the Otter Point Formation. Further, a detailed examination of the structural and stratigraphic relationships between the Otter Point Formation and the Eocene Roseburg and Lookingglass Formations was to be performed in an attempt to determine the tectonic history of the area.
