Petrie, Meredith Blair. "Evolution of eclogite facies metamorphism in the St. Cyr klippe, Yukon-Tanana terrane, Yukon, Canada". Thesis, The University of Iowa, 2016. http://pqdtopen.proquest.com/#viewpdf?dispub=3628428.
Pełny tekst źródłaThe St. Cyr klippe hosts well preserved to variably retrogressed eclogites found as sub-meter to hundreds of meter scale lenses within quartzofeldspathic schists in the Yukon-Tanana terrane, Canadian Cordillera. The St. Cyr area consists of structurally imbricated, polydeformed, and polymetamorphosed units of continental arc and oceanic crust. The eclogite-bearing quartzofeldspathic schists form a 30 by 6 kilometer thick, northwest-striking, coherent package. The schists consist of metasediments and felsic intrusives that are intercalated on the tens of meter scale. The presence of phengite and Permian age zircon crystallized under eclogite facies metamorphic conditions indicates that the eclogite was metamorphosed in situ with its quartzofeldspathic host.
I investigated the metamorphic evolution of the eclogite-facies rocks in the St. Cyr klippe using isochemical phase equilibrium thermodynamic (pseudosection) modeling. I constructed P-T pseudosections in the system Na2O-K2O-CaO-FeO-O2-MnO-MgO-Al2O 3-SiO2-TiO2-H2O for the bulk-rock composition of an eclogite and a host metatonalite. In combination with petrology and mineral compositions, St. Cyr eclogites followed a five-stage clockwise P-T path. Peak pressure conditions for the eclogites and metatonalites reached up to 3.2 GPa, well within the coesite stability field, indicating the eclogites reached ultrahigh-pressure conditions. Decompression during exhumation occurred with a corresponding temperature increase.
SHRIMP-RG zircon dating shows that the protolith of the eclogites formed within the Yukon-Tanana terrane during early, continental arc activity, between 364 and 380 Ma, while the metatonalite protolith formed at approximately 334 Ma, during the Little Salmon Cycle of the Klinkit phase of Yukon-Tanana arc activity. Both the eclogites and the metatonalites were then subducted to mantle depths and metamorphosed to ultrahigh-pressure conditions during the late Permian, between 266 and 271 Ma. The results of our study suggest portions of the Yukon-Tanana terrane were subducted to high-pressure and ultrahigh-pressure conditions. This is the first report of ultrahigh-pressure metamorphism in the accreted terranes of the North American Cordillera. Petrological, geochemical, geochronological, and structural relationships link the eclogites at St. Cyr to other eclogite localities in Yukon, indicating the high-pressure assemblages form a larger lithotectonic unit within the Yukon-Tanana terrane.

Pełny tekst źródłaThe success of heritage conservation districts as a more holistic approach to heritage resource management has been documented around the country. Yukon, Canada has expressed a desire to move beyond traditional approaches to establish district designations. Through detailed examinations of the evolution of districts and of the progression of historic sites management in Canada and the Yukon, best practices will be established and measured against the unique challenges faced in the Territory. Further, an examination of the potential benefits and challenges are discussed and measured against three case studies: downtown Dawson City, Takhini North in Whitehorse and Carcross, Yukon. The case studies provide tangible evidence for the successful implementation of heritage conservation districts as a way to preserve and enhance the Yukon's historic sites.

De, krom Valentina. "A geomorphic investigation of retrogressive thaw slumps and active layer slides on Herschel Island, Yukon Territory /". Thesis, McGill University, 1990. http://digitool.Library.McGill.CA:80/R/?func=dbin-jump-full&object_id=59632.
Pełny tekst źródłaRetrogressive thaw slumps developed in areas of low to moderate slopes underlain by a variety of sediments with ice contents up to 4500% (on a dry weight basis). Slump headwall retreat rates of up to 19.5 m/yr were recorded. By comparison, active layer slides developed on steeper slopes underlain mainly by marine silts and clays. The sediments exposed in the slide floors and headwalls displayed no visible ground ice, but moisture contents were between 15-35%. Retrogressive thaw slumps and active layer slides form by entirely different processes. However, they do occur in close association and are influenced by many of the same parameters.

Pełny tekst źródłaThe availability of airborne and spaceborne imagery in the arctic over the last fifty years has made possible the temporal analysis of permafrost and ground ice-related erosion. The objectives of this thesis are (1) the creation of a large scale database for horizontal coastal retreat on Herschel Island for the 1952-2000 timespan, (2) the investigation of retrogressive thaw slump activity over the same period and its relation to coastal erosion, and (3) the elaboration of stereophotogrammetric techniques to investigate retrogressive thaw slump activity volumetrically. Herschel Island, located on the northern coast of the Yukon Territory, was chosen as the study site for this research, because of the widespread presence of retrogressive thaw slumps and the lack of data for coastal erosion during the last fifty years.
Photogrammetric tools were used to create orthorectified and stereo-images of the Island for the years 1952, 1970, 2000 and 2004 from airphoto archives and Ikonos (1 m resolution) imagery. Coastal erosion was found to be stable or declining on Herschel Island except in the vicinity of retrogressive thaw slumps. In addition, retrogressive thaw slumps were identified on the imagery and observed to have increased in frequency for the 1952-2000 period.
Stereophotogrammetric analysis of two retrogressive thaw slumps showed that eroded sediment volumes from these landforms are considerable and should be included in future assessments of sediment release from arctic coasts to the oceanic shelves.

Pełny tekst źródłaLe changement rapide du climat actuellement observé dans l'Arctique de l'Ouest Canadien devrait avoir une influence majeure sur le pergélisol représentant plus de la moitié de la masse continentale du Canada. L'isolement de ces vastes étendues a limité les efforts de recherche scientifique à leur sujet et par conséquent le niveau de connaissances des caractéristiques du pergélisol. Plus particulièrement, peu d'information existe au sujet des unités massives de glace de sol, c'est-à-dire de grands corps tabulaire de glace avec une teneur en humidité gravimétrique supérieure à 250% (pour cent en poids sec), que l'on retrouve dans ces régions. Ces glaces de sol peuvent provenir de l'enterrement d'étendue de glace en surface, tels que des glaciers, des bancs de neige, ou encore de la congélation in situ d'eaux souterraines, autrement nommées glaces intrasedimental. La glace de sol peut fournir de précieuse information sur l'historique et l'évolution des climats passés. La haute teneur en eau congelé dans la glace peut causer d'importants changements dans la topographie, pour les infrastructures et ultimement pour les habitants de cette région qui font usage du sol.Situé dans le mur de tête de glissements de dégel rétrogressif de l'île Herschel au Yukon, des affleurements de glace souterraine fournissent un cadre idéal pour étudier des unités de glace ayant des origines incertaines. Pour la présente étude, dix-sept unités de glace massive distinctes, observée dans quatre expositions différentes, ont été échantillonnés pour l'analyse en laboratoire. Le but de cette recherche est de comprendre l'origine de ces unités de glace massive moins bien connues en faisant usage d'un outil récemment développé permettant d'analyser les rapports molaires entre differents gaz atmosphériques occlus à l'intérieur des unités de glace. Cette approche repose sur la méthode reconnue de cryostratigraphy, sur l'analyse d'isotopes stables O-H ainsi que sur des mesures géochimiques. Les résultats de ces tests, présentés en deux manuscrits, révèlent une histoire cryotique complexe identifiant des unités de glace massive avec des caractéristiques atmosphériques et intrasedimental.Une unité isolée de glace blanche ayant été observée dans la partie supérieure d'un glissements de dégel rétrogressif présente une signature atmosphérique forte avec de faibles ratios de gaz atmosphériques N2/Ar ainsi qu'une droite de régression δD vs. δ18O qui se rapproche étroitement de la ligne d'eau locales météorique. L'hypothèse d'une origine atmosphérique pour cette unité de la glace est soutenu par de faibles valeurs de conductivité mesurées à meme l'unité de la glace. Ces études chimiques combinées à un examen cryostratigraphique tout aussi concluant suggèrent que cette unité massive de glace est en fait un banc de neige récemment enterré. Un modèle d'enterrement de banc de neige est également présenté à clarifier pour appuyer cette conclusion.Une unité distincte de glace de couleur bleue exposée par un bluff océanique contient des gaz occlus avec des ratios molaires de N2/Ar et de O2/Ar fortement corrélées aux mêmes ratios mesurées dans l'atmosphère actuel. Deux des unités mesurées révélé une origines de glace intrasedimental en raison du faible taux de N2/Ar gaz atmosphériques et d'une conductivité élevée. Une troisième unité de glace blanche isolée et confinée reflète un ratio molaire des gaz N2/Ar fortement corrélée avec le ratio N2/Ar de l'atmosphère actuel. Une origine atmosphérique pour cette unité de glace est aussi soutenue par une ligne de régression δD vs. δ18O similaire à celle de l'LMWL.Ces résultats fournissent une nouvelle couche d'interprétation qui s'ajoute aux connaissances précédemment établies et fournissent une explication plus robuste quant à l'origine des unités de glace massive sur l'île Herschel.

Pełny tekst źródłaDegradation of ice-rich granular resources is expensive and difficult to rehabilitate and can cause developmental thermokarst, overestimation of granular resources, disturbance of wildlife habitat and create conflicts with traditional land uses.
To locate massive ice we used a resistivity geophysical technique and to characterize the ice we used geochemical, petrographic and stratigraphic techniques. The resistivity technique detected bodies of massive ice and ice-rich sediments and coarse-grained sediments at high resolutions and laboratory analysis reveal that the ice was of glacial origin.
These findings indicate that massive ice of glacial origin occurs in coarse-grained sediments in permafrost. The techniques used in this study could form the basis of a predictive model of massive ice occurrence.
