Cette thèse porte sur deux suites de roches métamorphiques de haute-pression et haute température provenant de l'Orogène Tibeto-Himalayen. La première suite de roches consiste en des affleurements d'amphibolites à grenat et clinopyroxène se retrouvant sous la forme de blocs dans le mélange ophiolitique à matrice de serpentine sous-jacent aux ophiolites de la Zone de Suture du Yarlung Zangbo, au Sud Tibet. La Zone de Suture du Yarlung Zangbo est un linéament de plus de 2000 km de long situé à la bordure méridionale du plateau Tibétain, au nord de la crête Himalayenne. Elle contient les reliques du vaste océan qui séparait l'Inde du Tibet pendant le Jurassique et le Crétacé : la Téthys. Dans la suture, des fragments de lithosphère océanique ont été préservés sous la forme d'une ceinture ophiolitique discontinue sous laquelle se retrouve un mélange ophiolitique. Les roches documentées dans la première partie de cette thèse ont été échantillonnées dans les occurrences de Bainang et de Angren/Buma, près de Xigaze, et plus à l'ouest sous l'ophiolite de Saga. Les relations de terrain suggèrent que ces roches représentent une semelle sub-ophiolitique démembrée. Sur la base des teneurs en éléments majeurs et traces de ces roches, cette semelle métamorphique aurait une affinité de N-MORB ou de BABB très similaire à celle de la croûte des ophiolites sus-jacentes. La géochronologie en Ar/Ar sur hornblende indique un âge de refroidissement entre 130 et 123 Ma. Considérant les modélisations complétées pour d'autres semelles métamorphiques dans le monde, ces âges peuvent également être considérés comme datant de très près le pic métamorphique. Les conditions du pic métamorphique on été contraintes thermobarométriquement et sont supérieures à 13 kbar et 800°C avec des moyennes dans l'ordre de 15 kbar et 850°C. Les relations de terrain, les données de littérature concernant les unités associées ainsi que la géochimie, la géochronologie et l'histoire métamorphique de la semelle subophiolitique de la Zone de Suture du Yarlung Zangbo supportent le modèle géodynamique suivant. Pendant le Jurassique ou le Crétacé Inférieur, la croûte des ophiolites du Yarlung Zangbo et le protolithe de sa semelle métamorphique sont formés à un centre d'expansion situé dans une zone de supra-subduction comprenant un bassin d'arrière-arc mature. Vers 130 Ma, une perturbation tectonique majeure change la direction relative des plaques et force l'initiation d'une nouvelle subduction localisée sur la ride d'extension du bassin arrière-arc. Le résultat est une ophiolite d'affinité d'arrière-arc piégée en contexte d'avant-arc et sous laquelle se retrouve une semelle métamorphique du faciès des granulites de haute-P et d'affinité d'arrière-arc. La deuxième suite de roches étudiée dans cette thèse consiste en des migmatites alumineuses à kyanite retrouvées dans le coeur de l'Antiforme du Namche Barwa, au sein de la Syntaxie Himalayenne Orientale. Le coeur de l'Antiforme du Namche Barwa est un dôme métamorphique à extrusion très rapide montrant des taux de denudation et d'exhumation extrêmes (~10mm/a). Il est situé à l'extrémité orientale de la chaîne Himalayenne et comporte la gorge la plus profonde de la planète. Les roches étudiées se retrouvent sous la forme de lentilles enrobées dans le gneiss migmatitiques à sillimanite qui forme la majorité du coeur de l'antiforme. Les lentilles migmatitiques à kyanite, d'âge Éocène-Oligocène (Zhang et al. 2010), ont été interprétées comme représentant la croûte inférieure du plateau Tibétain mais leur pic métamorphique dans le faciès des granulites de haute-pression était jusqu'à aujourd'hui contesté. Dans la présente étude, ces roches ont été investiguées quant à leur minéralogie, leur géochimie, les relations texturales entre les minéraux qui les composent et leur chimie minérale. Les résultats ont été interprétés à l'aide de pseudosections. L'interprétation confirme que ces roches représentent des protolithes sédimentaires alumineux ayant été enfouis à des conditions de croûte inférieure de l'ordre de 15 kbar et 850°C où ils ont perdu une proportion de leur liquide anatectique. Cependant, une proportion significative de liquide anatectique est restée piégée dans le réseau cristallin réfractaire, donnant lieu à d'importantes modifications texturales pendant l'exhumation jusqu'à des conditions de l'ordre de 10 kbar et 800°C, correspondant à la solidification finale du liquide piégé. Les résultats des modélisations suggèrent également que le potentiel de fusion par décompression d'une croûte inférieure aussi chaude est très faible puisque la plus grande proportion du liquide anatectique est produite pendant l'enfouissement. Cette étude démontre que la croûte inférieure Tibétaine était déjà fortement épaissie et très chaude peu après la collision initiale Éocène

High to ultrahigh temperature contact metamorphism and dry partial melting of the Tasiuyak paragneiss, Northern Labrador( )

1 edition published in 2014 in English and held by 1 WorldCat member library worldwide

Abstract Contact aureoles of the anorthositic to granitic plutons of the Mesoproterozoic Nain Plutonic Suite (NPS), Labrador, are particularly well developed in the Palaeoproterozoic granulite facies, metasedimentary, Tasiuyak gneiss. Granulite facies regional metamorphism (MR), c. 1860 Ma, led to biotite dehydration melting of the paragneiss and melt migration, leaving behind biotite-poor, garnet-sillimanite-bearing quartzofeldspathic rocks. Subsequently, Tasiuyak gneiss within a c. 1320 Ma contact aureole of the NPS was statically subjected to lower pressure, but higher temperature conditions (MC), leading to a second partial melting event, and the generation of complex mineral assemblages and microstructures, which were controlled to a large extent by the textures of the MR assemblage. This control is clearly seen in scanning electron microscopic images of thin sections and is further supported by phase equilibria modelling. Samples collected within the contact aureole near Anaktalik Brook, west of Nain, Labrador, mainly consist of spinel-cordierite and orthopyroxene-cordierite (or plagioclase) pseudomorphs after MR sillimanite and garnet, respectively, within a quartzofeldspathic matrix. In addition, some samples contain fine-grained intergrowths of K-feldspar-quartz-cordierite-orthopyroxene inferred to be pseudomorphs after osumulite. Microstructural evidence of the former melt includes (i) coarse-grained K-feldspar-quartz-cordierite-orthopyroxene domains that locally cut the rock fabric and are inferred to represent neosome; (ii) very fine- to medium-grained cordierite-quartz intergrowths interpreted to have formed by a reaction involving dissolution of biotite and feldspar in melt; and (iii) fine-scale interstitial pools or micro-cracks filled by feldspar interpreted to have crystallized from melt. Ultrahigh temperature (UHT) conditions during contact metamorphism are supported by (i) solidus temperatures>900 °C estimated for all samples, coupled with extensive textural evidence for contact-related partial melting; (ii) the inferred (former) presence of osumilite; and (iii) titanium-in-quartz thermometry indicating temperatures within error of 900 °C. The UHT environment in which these unusual textures and minerals were developed was likely a consequence of the superposition of more than one contact metamorphic event upon the already relatively anhydrous Tasiuyak gneiss

Anatectic record and contrasting P-T paths of aluminous gneisses from the central Grenville Province( )

1 edition published in 2014 in English and held by 1 WorldCat member library worldwide

Abstract Anatectic aluminous gneisses, some derived from sedimentary rocks of broadly pelitic composition and others from hydrothermally altered felsic volcanic rocks, are exposed in the mid-P and high-P segments of the hinterland in the central Grenville Province. These gneisses consist dominantly of garnet, biotite, K-feldspar, plagioclase and quartz, with sillimanite or kyanite, and display microstructural evidence of anatexis by fluid-absent reactions consuming muscovite and/or biotite. Melt-related microstructures, such as inter-granular films and/or interstitial quartz or feldspar enclosing relict phases, are most abundant in the metasedimentary samples. Despite anatexis at granulite facies conditions, the hydrothermally altered rocks preserve earlier features attributed to the circulation of hydrothermal fluids, such as sillimanite seams, dismembered quartz veins and garnet-rich aluminous nodules in a K-feldspar-dominated matrix. Microstructural and mineral chemical data, integrated with P-T pseudosections calculated with thermocalc for the metasedimentary rocks, permit qualitative constraints on the P-T paths. Data from a high-P kyanite-bearing sample are consistent with a steep prograde P-T path up to ~14.5 kbar and 860-900 °C, followed by decompression with minor cooling to the solidus at ~11 kbar and 870 °C. This pressure-dominated P-T path is similar to those inferred in other parts of the high-P segment in the central Grenville Province. In contrast, the P-T path predicted from a mid-P sillimanite-bearing paragneiss has a strong temperature gradient with P-T of ~9.5 kbar and 850 °C at the thermal peak, and a retrograde portion down to ~8 kbar and 820 °C. In a broad sense, these two contrasting P-T patterns are consistent with predictions of thermo-mechanical modelling of large hot orogens in which P-T paths with strong pressure gradients exhume deeper rocks in the orogenic flanks, whereas P-T paths with strong temperature gradients in the orogenic core reflect protracted lateral transport of ductile crust beneath a plateau

An electron-optical study of melt-related microstructures in granulite facies rocks from the Torngat Orogen( )

1 edition published in 2014 in English and held by 1 WorldCat member library worldwide

Abstract Cordierite-quartz and plagioclase-quartz intergrowths in a paragneiss from northern Labrador (the Tasiuyak Gneiss) were studied using SEM, STEM and TEM. The gneiss experienced granulite facies conditions and partial melting during both regional and, subsequently, during contact metamorphism. The microstructures examined all results from the contact metamorphism. Cordierite-quartz intergrowths occur on coarse and fine scales. The former sometimes exist as a 'geometric' intergrowth in which the interface between cordierite and quartz appears planar at the resolution of the optical microscope and SEM. The latter exists in several microstructural variants. Plagioclase is present as a minor component of the intergrowth in some examples of both the coarse and fine intergrowth. Grain boundaries in cordierite-quartz intergrowths are occupied by amorphous material or a mixture of amorphous material and chlorite. Cordierite and quartz are terminated by crystal faces in contact with amorphous material. Chlorite is sometimes found on cordierite surfaces and penetrating into cordierite grains along defects. Quartz contains (former) fluid inclusions 10-20 nm in maximum dimension. The presence of planar interfaces between cordierite and the amorphous phase is reminiscent of those between crystals and glass in volcanic rocks, but in the absence of compelling evidence that the amorphous material represents former melt, it is interpreted as a reaction product of cordierite. Plagioclase-quartz intergrowths occur in a number of microstructural variants and are commonly associated with cordierite-quartz intergrowths. The plagioclase-quartz intergrowths display simple, non-planar interfaces between plagioclase and quartz. Quartz contains (former) fluid inclusions of dimensions similar to those observed in cordierite-quartz intergrowths. The boundary between quartz and enclosing K-feldspar is cuspate, with quartz cusps penetrating a few tens of nanometres into K-feldspar, commonly along defects in K-feldspar and sometimes with very low dihedral angles at their tips. This cuspate microstructure is interpreted as melt pseudomorphs. The plagioclase-quartz intergrowths share some features with myrmekite, but differ in some respects: the composition of the plagioclase (An37Ab62Or1-An38Ab61Or1); the association with cordierite-quartz intergrowths; and microstructures that are atypical of myrmekite (e.g. quartz vermicules shared with cordierite-quartz intergrowths). It is inferred that the plagioclase-quartz intergrowths may have formed from, or in the presence of, melt. Inferred melt-related microstructures preserved on the nanometre scale suggest that melt on grain boundaries was more pervasive than is evident from light optical and SEM observations
