Abstract:

AbstractThe Lower Palaeozoic Bonney Pluton is a regionally extensive coarse-grained, variably megacrystic, monzodioritic to granitic body that crops out over 1000 km2 in South Victoria Land. It intruded upper amphibolite facies Koettlitz Group metasediments and interlayered orthogneisses. Magmatic fabrics are developed in the centre of the pluton by flow alignment of K-feldspars before the majority of phases had crystallized, whereas solid-state fabrics developed in the pluton margins by ductile–plastic deformation. Structures developed in the host-rocks vary around this elongate northwest–southeast-trending pluton. Upright, tight northwest–southeast-trending macroscopic folds are developed at the sides of the pluton, with axis-parallel stretching lineations and boudinage indicating strong northwest–southeast extension. Broad warps of tight macroscopic folds, and mesoscopic refolded folds, sheath folds and complicated interference patterns characterize areas at the ends of the pluton. Emplacement of the pluton involved radial expansion in a regional northeast–southwest compression, and growth predominantly in the northwest–southeast direction. Superposition of the radial expansion and regional compression resulted in an inhomogeneous strain field at a regional scale, with coaxial strain at the sides of the pluton and non-coaxial strain at the ends. Upright folds developed at the pluton's sides, and became tighter with continued coaxial deformation. Non-coaxial structures developed at the ends of the pluton and were pushed aside by the growing pluton into areas of coaxial deformation, resulting in complex folding, re-folding and sheath folds. Metamorphism of the host-rocks and migmatite development was more intense at the sides of the pluton than near the ends, possibly due to different P-T-t paths of host-rocks around syntectonic plutons.

Abstract:

The Volcanic Arc Suite is the group of batholiths in the range of the Barisan Mountains and mostly denotes I-type affinity. Previous investigations of the intrusions in West Sumatra emphasized the crystallization age without completing geochemistry characteristics. No former study discussed a pluton which mapped in the Kota XI Tarusan District. This study explains the geochemistry and petrology of the Tarusan Pluton using polarized microscope, XRF, and ICP-MS at the Center for Geology Survey of Indonesia. The microscopic analysis confirms the granite character of the samples. Although both plutons are identified as I-type calc-alkaline series, the Tarusan Pluton is peraluminous granite whilst the Lolo Pluton denotes wider range from metaluminous to peraluminous of granodiorite to granite. Both the plutons are clearly classified as volcanic arc granitoid in the correlation to Volcanic Arc Suite of Sumatra. Negative Ba, Nb, and P anomalies together with positive K, Nd, and Y anomalies are pronounced on the two felsic intrusions. Negative Eu anomaly on the Tarusan Pluton but the positive one at the Lolo Pluton might explain different magma evolution process.Keywords: volcanic arc granite, geochemistry, Tarusan Pluton, Lolo Pluton.

Abstract:

The 1167 ± 2 Ma Leo Lake pluton, located at the southern part of the Frontenac terrane in Central Metasedimentary Belt of southeastern Ontario, is a bimodal pluton that is dominated by olivine gabbro, gabbro, syenite, and lesser monzonite. The adjoining 1166 ± 3 Ma Lyndhurst pluton is composed of syenite and granite, and exhibits magma mingling. Even though geochemical data from both plutons suggest fractional crystallization as the main crystallization process, magma mingling is evident in the Lyndhurst pluton. Hornblende from the Leo Lake syenite yields a 40Ar–39Ar age of 1120 ± 6 Ma and titanite from the adjacent St. Lawrence skarn yields a U–Pb age of 1147 ± 8 Ma. The 40Ar–39Ar age indicates that the pluton cooled to 550 °C at a rate of ca. <2 °C/Ma following emplacement. The two plutons are similar in petrology to several other granitic, syenitic, and monzonitic intrusions of the Frontenac suite in the Frontenac terrane. Moreover, the spatial distribution, textural features, and geochemistry indicate that the plutons are coeval. The present data indicate that the two plutons may have been produced from evolved mantle-derived melts, and may have assimilated varying proportions of crustal melts.

Abstract:

Analysis of folding in the southwestern Vermilion granitic complex suggests that F2 folds, which formed in a regional north–south compressional regime, were locally reoriented during pluton emplacement and were subsequently refolded by F3 folds generated by continuing north–south compression. An east–west-trending F2 antiform, crossing the boundary between the southern Vermilion granitic complex and the adjacent Vermilion district, was intruded by a tonalite pluton during the later stages of F2 folding. Either emplacement of the pluton or emplacement of the nearby Lac La Croix batholith is believed to have reoriented the F2 fold so that, subsequently, the pluton and the F2 antiform were refolded by a doubly plunging east–west-trending F3 fold, now cored by the pluton.A similar relationship occurs between F2 and F3 folds north of the Vermilion fault in the main portion of the complex. Here, F3 conical folds, not cored by plutons, refold F2 folds about northwest-trending vertex axes. Analysis of the refolding of minor F2 folds and L2 lineations in this area suggests they were nearly coaxial with the F3 folds prior to the F3 folding.

Abstract:

The Serra da Graciosa region includes important occurrences of granites and syenites of the Graciosa A-type Province (formerly Serra do Mar Suite), southern Brazil. Using fieldwork, petrography, and remote sensing imagery, we characterize the geology of the plutons in the region. Five individual plutons were recognized. Two correspond to the previously defined Marumbi and Anhangava Plutons. We divide the former "Graciosa Pluton" into three new plutons: Capivari, Órgãos, and Farinha Seca. The plutons are elliptical with northeast-southwest orientation. Two petrographic associations can be recognized: an alkaline association that includes peralkaline and metaluminous hypersolvus alkalifeldspar granites and syenites (Anhangava, Farinha Seca, Órgãos), and an aluminous association composed of metaluminous and weakly peraluminous subsolvus granites (Capivari, Órgãos, Anhangava, Marumbi). Occurrences of each association are limited to one individual pluton or to portions of a pluton, and the age relationships are not well established. Monzodioritic rocks are found marginal to the Órgãos and Farinha Seca Plutons, and interaction with silicic magmas locally produced hybrid quartz syenites (Farinha Seca Pluton). Geothermobarometry indicates emplacement at shallow crustal levels (P = 2 ± 0.6 kbar), and crystallization temperatures within the interval 900-700ºC for the granitic and syenitic rocks, and 1000-750ºC for the monzodioritic rocks.

Abstract:

Synmagmatic and solid-state structures within the Naxos pluton and its rim may provide insight into the interplay between plutonism and regional deformation at upper-crustal level. Within the hornblende–biotite granite of western Naxos, synmagmatic foliations display two distinct patterns, onion-skin in the north and tangential to the rim in the south. The two areas are separated by the NE-trending Glinadon fault. Deformed mafic enclaves in the pluton are prolate, with their long axes parallel to the synmagmatic lineation. In contrast, phenocryst distribution analysis, using the Fry method, defines an apparent oblate strain with a horizontal stretching lineation. Planar markers within the pluton progressively steepen through the vertical at the east pluton border. Several lines of evidence, such as dykes intruding axial areas of rim-parallel folds, foliated or folded aplite veins, folds and spaced cleavage in the mollase, and inverted stratigraphy, suggest pluton emplacement and deformation during transpressional deformation. A northward divergent flow regime with magma spreading out mainly from the Naxos fault, and the deflection of both the synmagmatic foliation pattern and the flow lines at the Glinadon fault, suggest that the NE–SW- and N–S-trending faults were active during pluton formation. In the south the pluton has grown by the expansion of dykes occupying P-shear positions with respect with the Naxos fault; in the north a piecemeal block down-drop complements this process and favours voluminous magma concentration. During the late evolutionary stages of pluton construction, the magma chamber was compartmentalized into NE-trending sectors affected by block rotation in an anticlockwise manner. Understanding the role of faults in the emplacement of the Naxos pluton is important for understanding emplacement of other plutons in the Aegean Sea region, since most of them are controlled by N–S- (Ikaria pluton) or NE- (Tinos, Serifos and Delos plutons) trending faults.

Abstract:

Nine new U-Pb ages are reported for plutons of the central granite-gneiss zone of the Abitibi belt in Quebec. The large plutonic complex along Lithoprobe seismic reflection line 28 formed by multiple intrusion over at least 40 million years, synchronous with and postdating formation of adjacent volcanic sequences. Ages for the four principal plutons within the complex are: Mistaouac at 2726 ± 2 Ma, Boivin at 2713 ± 2 Ma, Rousseau at 2703 ± 2 Ma, and Paradis at 2686 ± 2 Ma. The latter also constrains deformation within the Laberge deformation zone to be at least in part younger than 2686 Ma. Inherited zircons in the Mistaouac pluton indicate that the oldest pluton formed in significantly older crust (>2.75 Ga), not presently exposed in the area. The La Reine and Waswanapi plutons have ages of ca. 2695 Ma similar to other tonalitic plutons in the area and elsewhere in the Abitibi belt. A syenite pluton deformed within the Douay fault zone, a late fault associated with the Casa Berardi zone, has an age of 2676+6-5 Ma, similar to alkalic plutons associated with the Destor-Porcupine and Cadillac-Larder Lake deformation zones of the southern Abitibi belt. Two samples from the Lac Case pluton yielded monazite ages of 2676 ± 3 and 2660 ± 3 Ma. Nd, Pb, and Sr isotopic compositions for central Abitibi belt plutons show dominantly juvenile sources with minor contributions of older crust in the Lac Case pluton. Although geochronological data for volcanic rocks has been used to suggest that the northern zone is older and magmatic activity youngs to the south, consideration of the ages for plutonic and volcanic rocks does not support such hypothesis. The available data indicate that magmatism occurred throughout the Abitibi subprovince from 2730 to 2685 Ma, permissive of a linked tectono-magmatic evolution for the northern and southern zones.

Abstract:

AbstractThe Castores and probably the Santa Rosa plutons of north-west Isla Navarino, southern Chile, have been emplaced by in situ diapirism into metasedimentary rocks of the Upper Jurassic (?)–Lower Cretaceous Yaghan Formation. For the former, this model is consistent with the concentric foliation paralleling the margin of the pluton and the foliation and stratification planes in the metamorphic aureole. Only the southern part of the Santa Rosa Pluton is preserved, and it has some structures similar to those of the Castores Pluton, which can also be interpreted as produced by an inflating diapir. The main intrusive rocks of these plutons are quartz-monzodiorites and quartz-diorites with synmagmatic foliation. They were preceded by minor bodies of hornblende gabbros, and followed by dykes and small bodies of non-foliated granodiorites. Non-foliated to weakly foliated granodiorites, forming the centre of the Castores Pluton, probably represent a younger intrusive pulse.Twelve K–Ar mineral dates from 10 specimens of plutonic rocks, interpreted as near crystallization ages, span the period 80–90 Ma. These dates do not show the sequence of intrusion of the different rock-types, which may suggest that all of them were intruded and cooled in a short period of time. The timing of emplacement of these plutons in relation to tectonism is difficult to determine; however, a post-tectonic emplacement for at least the Castores Pluton, is proposed.

Abstract:

Northern Portugal is characterized by the occurrence of numerous W hydrothermal deposits spatially associated with granites. The primary goal of this work is to establish a relationship between the magnetic behavior of thegranites and the redox conditions during magma genesis, as this can influence the occurrence of mineralizations, namely of W (Mo). To this end, the magnetic mineralogy of the granites of the Lamas de Olo Pluton, a posttectonic pluton in northern Portugal, with associated W (Mo) occurrences was characterized and compared with the magnetic mineralogy of other post-tectonic Variscan plutons. This pluton is composed of different biotite granites: Lamas de Olo, Alto dos Cabeços and Barragem. To better characterize its magnetic behavior, differentanalytical techniques that complement previous magnetic susceptibility studies were performed. The magnetic mineralogy of Lamas de Olo Pluton was then compared with other post-tectonic Variscan plutons such as the Vila Pouca de Aguiar, Peneda-Gerês and Lavadores-Madalena plutons. The presence of magnetite in some of these granites is important because it points to melt-oxidized conditions not commonly found in Iberian Variscan granites. Our study shows that granite areas where magnetite and/or magnetite/ilmenite coexist are important targets for W (Mo) mineralizations. The results indicate that a few plutons have granites with a complex redox history which leads to the formation of magnetite and ilmenite.

Abstract:

Le 14 juillet 2015, la sonde New Horizons a survolé Pluton et a révélé un monde glacé débordant d’activité. Pour interpréter les observations, nous avons développé deux modèles numériques, l’un simulant les interactions surface-atmosphère des espèces volatiles sur des milliers d’années, l’autre dédié au climat 3D complet de Pluton. Avec ces modèles, nous analysons les cycles annuels et paléoclimatiques des glaces. Nos simulations reproduisent la distribution des espèces volatiles observées à la surface de Pluton, ainsi que leur abondance dans l’atmosphère. Nous montrons que l’insolation sur Pluton et la nature de son atmosphère favorisent la condensation d’azote au fond du bassin Sputnik Planitia, comme observé. Nous simulons, sur des échelles de millions d’années, des écoulements glaciaires de la calotte de glace dans Sputnik Planitia, ainsi que la formation de glaciers de méthane à l’équateur, des résultats très cohérents avec les observations. Nous nous intéressons ensuite à l’état de l’atmosphère de Pluton en 2015 avec le modèle 3D, caractérisant les régimes de vents, formation des nuages, températures, etc.... Nos derniers résultats mettent en évidence la sensibilité de la circulation générale à la distribution de la glace d’azote à la surface et suggèrent une rétro-rotation dans l’atmosphère de Pluton, induite par les flux de condensation-sublimation de l’azote dans Sputnik Planitia. Nous montrons également que plusieurs phénomènes sont à l’origine de la couche limite froide observée dans Sputnik Planitia. Enfin, en reproduisant les processus qui mènent à la formation de la brume organique, nous parvenons à expliquer l’extension de la brume observée au pôle nord
On July 14, 2015, the New Horizons spacecraft flew by Pluto and revealed an active frozen world.These observations call upon modelling efforts to complete their analysis and understand the mechanisms at play on Pluto. For this purpose, we have developed two numerical models of Pluto’s climate: a 2D model dedicated to the study of Pluto’s surface and a 3D model of Pluto’s atmosphere. We analyse the annual and paleoclimatic volatile cycles. Our simulations reproduce the distribution of the volatile observed on Pluto’s surface and their abundance in the atmosphere. We show that the solar insolation on Pluto and the nature of its atmosphere favour the condensation of nitrogen in the Sputnik Planitia basin, as observed. We simulate the glacial activity of the Sputnik Planitia ice cap on a timescale of millions of years, as well as the formation of methane glaciers at the equator. Our results are in agreement with the observations. We then focus on Pluto’s atmosphere in 2015 with the full 3D model where we performed a comprehensive characterization of the atmosphere: wind regimes, cloud formation, temperatures etc. ...We demonstrate the sensitivity of the general circulation to the distribution of the nitrogen ice on the surface and show that Pluto’s atmosphere currently undergoes retrograde rotation, induced by the condensation-sublimation of nitrogen in Sputnik Planitia. We also show that several phenomena originate at the cold boundary layer observed deep in Sputnik Planitia. Finally, by reproducing the processes that lead to the formation of organic haze, we simulate haze transport in the atmosphere and explain the greater extension of the haze observed at the north pole

Abstract:

Les occultations stellaires au sol sont une méthode très efficace pour sonder l'atmosphère (N2) d'azote de Pluton à quelques kilomètres de la surface (pressure ~10microbar) jusqu’à 380km altitude (~10nbar). Cette atmosphère est fortement couplée aux propriétés de surface de Pluton (distribution des glaces, inertie thermique et température de surface), car l'azote gazeux est en équilibre de pression de vapeur saturante avec la glace d'azote. Cela induit de forts effets saisonniers, dus à la grande obliquité (120 degrés) et à l'excentricité orbitale élevée (0,25) qui amène la planète naine de 30 à 50 ua pendant la moitié de sa période orbitale de 248 ans. Le sujet principal de ma thèse est une vue d'ensemble de vingt occultations d’étoiles au sol par la planète naine Pluton, organisées entre 2002 et 2016 par le groupe d'occultation du LESIA à l’Observatoire de Paris. Mon analyse de onze campagnes d'occultations avec un rapport S/N élevé a été utilisée pour: (1) déduire les changements de pression atmosphérique de Pluton sur des échelles de temps décennales (1988-2016) et créer des contraintes sur les modèles saisonniers actuels de la planète naine, les mettant en perspective avec le survol de la sonde NASA New Horizons en juillet 2015; (2) comparer nos résultats obtenus au sol avec les résultats de New Horizons, en particulier avec les résultats du radio science experiment (REX) au-dessous de 115 km d'altitude; (3) utiliser les géométries reconstruites des occultations et le nouveau catalogue Gaia DR2 pour améliorer les éléments orbitaux de Pluton et créer une nouvelle éphéméride pour la planète naine
Ground-based stellar occultations are a very efficient method to probe Pluto's tenuous nitrogen (N2) atmosphere from a few kilometers above the surface (pressure ~10 microbar) up to 380km altitude (~10nbar). This atmosphere is strongly coupled with Pluto's surface properties (distribution of ices, thermal inertia and surface temperature), as the gaseous N2 is in vapor pressure equilibrium with the nitrogen ice. This induces strong seasonal effects, due to the large obliquity (~120 deg) and high orbital eccentricity (0.25) that takes the dwarf planet from 30 to 50 au during half of its 248 year orbital period. The main topic of my thesis is an overview of twenty ground-based stellar occultations by the dwarf planet Pluto, that have been organized between 2002 and 2016 by the LESIA occultation group. My analysis of eleven campaigns of occultations with hight S/N ratio has been used to: (1) derive Pluto's atmospheric pressure changes on decadal time scales (1988-2016), and provide constrains on the current seasonal models of the dwarf planet, putting them in perspective with the NASA New Horizons flyby of July 2015; (2) compare our ground-based derived results with the New Horizons findings, and in particular with the results of the radio science (REX) experiment below the altitude ~115 km; (3) use the reconstructed geometries of the occultations and the newly released Gaia DR2 catalog to improve Pluto's orbital elements and provide an new ephemeris for the dwarf planet

ENGLISH ABSTRACT: The compositions of tonalite-trondhjemite-granodiorite (TTG)-series rocks from the Barberton Granite-Greenstone Terrain (BGGT) of Southern Africa vary in terms of major element concentrations (leuco-trondhjemites to tonalites), trace elements (e.g. Sr, Rb, REE) and degree of HREE depletion [(La/Yb)N ~ 0.50 - 121]. These geochemical parameters have been interpreted to have significance for the geodynamic processes that produced TTG magmas, particularly the depth of the source. In the Nelshoogte pluton, trondhjemite emplacement occurred prior to and during (D2)-tectonism, and hornblende-bearing tonalites/granodiorites occur as intrusive plugs within the trondhjemite. The geochemical range portrayed by the ca. 3230 Ma Nelshoogte pluton covers almost the whole range portrayed by all the TTG rocks of the BGGT, formed in the time interval 3550 to 3230 Ma. U-Pb zircon dating reveals no significant differences in apparent ages between the trondhjemites and tonalites of the Nelshoogte pluton; all lie between ca. 3240 and 3220 Ma. A/CNK- and Ti-maficity correlations within the Nelshoogte pluton show behaviour typical of I-type granitic rocks, confirming the metamafic character of the source and the involvement of a peritectic garnet and clinopyroxene component in the magmas. The REE and traceelement patterns resemble those of both ca. 3450 Ma TTG plutons and other ~ 3230 Ma TTG plutons in the BGGT. This suggests that these different generations of TTG magmas were generated from similar sources and by similar processes. The geochemical details are consistent with a metamafic source which underwent melting at high pressure. This TTG source was fundamentally different from the more potassic source/s that produced the younger 3100 Ma granites. Additionally, high Zr/Sm and low Nb/Ta ratios in the Barberton TTG rocks suggest that the Nelshoogte pluton originated as a group of chemically distinct magmas, in a similar way to other ~ 3200 Ma TTGs. The protoliths of ~ 3450 Ma plutons and ~ 3200 Ma plutons might typically be rutile-bearing eclogite and/or 10 to 30 % garnet bearing amphibolite. The geochemical features of the Barberton TTGs suggest similar source compositions, but different pressures of partial melting. For the ca. 3230 Ma plutons, the rocks of the Badplaas pluton and the Nelshoogte trondhjemites/tonalites correspond to the high-pressure magmas, as reflected by high Sr content, as well as high Sr/Y and (La/Yb)N ratios. In contrast, the Kaap Valley TTGs and Nelshoogte granodiorites reflect the melting of a similar source at moderate pressure. Furthermore, the Hf isotope data; Hft (+ 0.1 to + 1.9) and TDM model ages (3330 - 3230 Ma), suggest that the source rocks are ~ 20 to 100 Myr older than the pluton.
AFRIKAANSE OPSOMMING: Die samestellings van tonaliet-trondhjemiet-granodioriet (TTG)-reeks gesteentes vanaf die Baberton Graniet-Groensteen terrien (BGGT) van Suiderlike Afrika verskil in terme van hoofelement konsentrasies (leuko-trondhjemiete tot tonaliete), spoorelemente (bv. Sr, Rb en seldsameaarde-elemente(SAE)) en ook van swaar seldsameaarde-element (SSAE) uitputting [(La/Yb)N ~ 0.50 - 121]. Deur interpritasie is daar vasgestel dat hierdie geochemiese beperkings betekenis dra vir die geodinamiese prosesse wat TTG magmas produseer het, en veral vir die diepte van die bron. In die Nelshoogte pluton het trondhjemiet inplasing voor en gedurende (D2)-tektonisme voorgekom en horingblende-draende tonaliet/granodioriet kom voor as intrusiewe proppe binne-in die trondhjemiet. Die geochemiese reeks wat uitgebeeld is deur die ~ 3230 Ma Nelshoogte pluton ondersteun byna die hele reeks wat uitgebeeld is deur al die TTG gesteentes van die BBGT wat gevorm het gedurende die tydsinterval 3550 tot 3230 Ma. U-Pb sirkoon datering openbaar geen merkwaardige verskille in ouderdomme tussen die trondhjemiete en tonaliete van die Nelshoogte pluton nie. Al die ouderdomme lê tussen 3240 en 3220 Ma. A/CNK- en Ti-mafisiteit korrelasies binne die Nelshoogte pluton toon die tipiese gedrag van I-tipe granitiese gesteentes, en bevestig sodoende die metamafiese karakter van die bron, asook die betrokkenheid van ‘n peritektiese granaat en klinopirokseen component in die magmas. Die seldsameaarde-element en spoorelement patroone lyk soos dié van albei ~ 3450 Ma plutons en ander ~ 3230 Ma TTG plutons in die BGGT. Dit stel voor dat hierdie verskillende generasies van TTG magmas genereer was vanaf soortgelyke bronne en ook deur soortgelyke prosesse. Die geochemiese besonderhede stem ooreen met ‘n metamafiese bron wat smelting teen hoë druk ondergaan het. Hierdie TTG bron het fondamenteel verskil van die meer kalium-ryke bron/ne wat die jonger 3100 Ma graniete prodiseer het. In ‘n eenderse manier as ander ~ 3200 Ma TTG gesteentes, stel hoë Zr/Sm en lae Nb/Ta verhoudings in die Baberton TTG gesteentes verder voor dat die Nelshoogte pluton ontstaan het as ‘n groep chemies verskillende magmas. Die protoliete van ~ 3450 Ma plutons en ~ 3200 Ma plutons mag dalk tipies rutiel-draende eklogiet en/of 10 tot 30% granaat draende amfiboliet wees. Die geochemiese aspekte van die Baberton TTGs stel eenderse bron komposisies, maar verskillende drukke van gedeeltelike smelting voor.

Abstract:

Numerical models of conductive heat flow have been used to explore the connection between incremental pluton growth and large magma chambers. The simulations include repeated sill injections of melt into the crust using variable repose times in between these injections. Adopting this novel approach of a changing magma flux during the emplacement time of a pluton, different intrusion scenarios are tested to constrain the conditions for melt accumulation in the crust during progressive pluton growth. Results reveal that only a rapid increase in magma flux above a background value representative for plutons can lead to the formation of magma reservoirs. Field observations, image analysis (lA) with the intercept method and an anisotropy of magnetic susceptibility (AMS) study are conducted in the silicic Lago della Vacca Complex (LVC) in the Adamello Batholith, northern Italy, to gain insight into magmatic and magnetic fabrics. Combining this data enabled a detailed emplacement scenario for the LVC to be developed. Furthermore, a comparison between the results of lA and AMS shows that these methods are consistent, thus emphasising the applicability of lA and AMS in silicic rocks to reconstruct intrusion emplacement. This is the first comprehensive comparison between AMS and mineral fabrics, obtained by field measurements, lA and computer-assisted X-ray micro-tomography (X-ray /LCT) of which we are aware. The X-ray /LCT images provide the base to acquire the shape-preferred orientation (Spa) of magnetites and mafic silicates, and the spatial distribution of magnetites in a sample. Results show that the AMS signal is consistent with the spa of magnetite grains and clusters but differs from the distribution of the magnetites, suggesting that the AMS is controlled by magnetite grain shape. Moreover, the AMS agrees with the field measurements, lA and the spa of the mafic silicates underlining that lA and AMS can be applied to characterise fabrics in ferromagnetic granitoids. III

Abstract:

The Striped Rock pluton of the late-Proterozoic Crossnore Plutonic-Volcanic suite is located beneath the Fries Thrust zone in the Blue Ridge province of southwest Virginia. The multiphase granite pluton has been affected by episodes of brittle and crystal plastic deformation at both the microscopic and mesoscopic scales. Brittle deformation preceded and postdated crystal plastic deformation. The pluton is cut by pervasive centimeter-scale cataclasite zones and ductile shear zones that vary in width from a few millimeters to several hundred meters. The majority of mylonite zones in the pluton strike east and northeast and are inclined moderately southeast. Cataclasite zones strike northeast and northwest. Deformation is most intense along the southern contact with the Cranberry gneiss where both pluton and country rock are deformed into a northeast-striking zone of mylonitic augen gneiss. The intensity of deformation decreases northwestward. Southeastdirected normal fault displacement is common to east and northeast-trending shear zones. A minor group of northwest-oriented shear zones dip moderately southwest and northeast and show sinistral, strike-slip displacement. Quartz-, chlorite- and stilpnomelane-filled cracks and veins with northeast and northwest trend uniformly overprint mylonite and cataclasite zones of all scales. Microstructure changes progressively with increasing strain. Feldspar grains are cut by at least two generations of mineralized, dilatant microcracks. Minerals precipitated in the early set of microcracks have undergone extensive crystal plastic deformation. Late-stage microcracks are filled with completely undeformed minerals. The spatial distribution of normal fault mylonite zones is geometrically consistent with generation during 1) late-Proterozoic extension, 2) Mesozoic extension, 3) rigid-body rotation during Paleozoic thrusting, or 4) "gravitational collapse" during Paleozoic thrusting. Field and microstructural evidence favor (4). The exact timing of deformation is not, however, well-constrained.

Abstract:

Few plutons with a reversed geometry of a felsic rim and mafic core have been described in the geologic literature. The Turtle pluton of S.E. California is an intrusion composed of a granitic rim and granodioritic core and common microgranitoid enclaves. Field observations, mineral textures, and chemistries, major and trace element geochemistry, and isotopic variability support a petrogenetic model of in situ, concomitant, magma mixing, and fractional crystallization of rhyolitic magma progressively mixed with an increasing volume of andesitic magma, all without chemical contribution from entrained basaltic enclaves. Hornblende geobarometry indicates the Turtle pluton crystallized at about 3.5 kb. A crystallization sequence of biotite before hornblende (and lack of pyroxenes) suggests the initial granitic magma contained less than 4 wt% H₂0 at temperatures less than 780°C. U-Pb, Pb-Pb, Rb-Sr and oxygen isotope studies indicate the terrane intruded by the Turtle pluton is 1.8 Ga, that the Turtle pluton crystallized at 130 Ma, that the Target Granite and garnet aplites are about 100 Ma, and that these intrusions were derived from different sources. Models based on isotopic data suggest the rhyolitic end member magma of the Turtle pluton was derived from mafic igneous rocks, and was not derived from sampled Proterozoic country rocks. Similarity of common Sr and Pb isotopic ratios of these rocks to other Mesozoic intrusions in the Colorado River Region suggest the Turtle pluton and Target Granite have affinities like rocks to the east, including the Whipple Mountains and plutons of western Arizona. P-T-t history of the southern Turtle Mountains implies uplift well into the upper crust by Late Cretaceous time so that the heating and deformation events of the Late Cretaceous and Tertiary observed in flanking ranges did not affect the study area.

Abstract:

Un système multiple est un ensemble de petits corps du Système solaire en interaction gravitationnelle et orbitant autour du Soleil. Pour déterminer la valeur des paramètres physiques de ces objets, nous avons créé un modèle numérique à N-corps. Notre modèle prend en compte l'influence des planètes et des applatissements polaires au second ordre des objets. Il intègre les équations variationnelles associées aux mouvements orbitaux pour permettre un ajustement du modèle par la méthode des moindres carrés. Notre modèle a été appliqué au système de Pluton s'apparentant aussi bien aux systèmes planétaires classiques qu'à un système de petits corps. Dans un premier temps, en ajustant notre modèle à des observations simulées, nous avons étudié l'évolution de l'incertitude des masses de Nix et Hydra et avons montré que ces masses ne seront vraisemblablement contraintes que grâce aux observations de New Horizons. Nous avons également montré que nous ne pourrons déterminer les applatissements polaires des objets à partir des observations astrométriques seules. Nous avons également étudié la contribution de GAIA à notre connaissance du système. Par la suite, nous avons ajusté notre modèle aux observations réelles de ce système. Nous avons obtenu des valeurs des masses de Nix et Hydra très différentes de celles obtenues par de précédentes études en raison de la grande incertitude pesant sur ces masses. Nous avons ensuite utilisé le mouvement obtenu des satellites pour l'ajustement du mouvement héliocentrique de Pluton. Finalement, nous avons adapté notre modèle au système d'Eugenia pour lequel nous avons trouvé des résultats compatibles avec ceux des études précédentes
A system refers to a set of small bodies tied by gravitation and orbiting around their common center of mass, which orbits around the Sun. In order to deduce the value of those parameters, we have created an N-bodies numerical model. Our model includes the planetary perturbations as well as the integration of orbital motion's variationnal equations, a key feature of least-square method fitting. We applied our model to Pluto's system, which possesses features from both multiple and planetary systems. First, we have fitted our model to simulated data in order to study the evolution of the uncertainty on Nix's and Hydra's mass. We show that their mass will most probably remain unconstrained untill the arrival of New Horizons probe in the system. We also show that the effect of the polar oblateness on the orbits is cannot determined and studied the future contribution of GAIA to our knowledge of the system. Then, we have fitted our model to astrometric observations of the system. The fitting of the model to the observations has given very different masses for Nix and Hydra. Nonetheless, both in our study and the previous ones, the said masses are unconstrained enough for the results to remain coherent. The solution for the stellite's motion we then obtained has been used during our fitting of Pluto's heliocenter motion. At last, we have adapted our model to (45)Eugenia's system and have found results compatible with previous studies

Abstract:

Os Plutons Palermo (ca. 250 km2) e Rio Negro (ca. 130 km2) afloram na região Alto Rio Negro (PR) e fazem parte da Província Graciosa, uma província Neoproterozóica (ca. 580 Ma) constituída por granitos e sienitos na região S-SE do Brasil. Em ambos os plutons afloram variedades de rochas graníticas, predominantes, e gabro-dioríticas, bem como rochas híbridas, principalmente granodioritos. Estes plutons apresentam zonamento em geral bem marcado, que é tipicamente inverso caso do Pluton Rio Negro. As rochas graníticas principais correspondem a sieno- e monzogranitos predominantes e álcali-feldspato granitos e quartzo monzonitos subordinados de natureza metaluminosa a levemente peraluminosa. São rochas com estruturas maciças e texturas variadas que apresentam como associação mineral máfica típica hb + bi ± all + zr + ap ± ti + mt + ilm); as rochas gabro-dioríticas incluem gabro-dioritos e quartzo monzogabro-dioritos metaluminosos com estruturas maciças e granulações fina a média, caracterizadas pela associação cpx ± opx + hb + bt ± ti ± ap ± zr. A composição dos plagioclásios nestas rochas varia no intervalo de labradorita a andesina. As rochas híbridas são principalmente granodioritos que se caracterizam por uma variedade de estruturas e texturas indicativas de desequilíbrio, compatíveis com processos de coexistência e mistura parcial entre líquidos ácidos e básico-intermediários que formaram os granitos principais e os gabro-dioritos. Estas rochas são mais comuns no Pluton Rio Negro. A associação mineral máfica é similar, mas com abundâncias distintas de fases, à observada para os granitos principais. Nas rochas graníticas os anfibólios são Fe-hornblenda e Fe-edenita, com valores 0,65 < fe# < 0,95, os valores mais elevados ocorrendo nos álcali-feldspato granitos, as biotitas apresentam 0,71 < fe# < 0,99, observando-se que o componente annítico é também maior nestas últimas rochas. No caso das rochas gabro-dioríticas, os valores fe# variam entre 0,48 e 0,59, 0,41 e 0,56, 0,47 e 0,53 e 0,54 a 0,57 para ortopiroxênio, clinopiroxênio, anfibólio e biotita, respectivamente. As composições médias de orto- e clinopiroxênio coexistentes são \'Wo IND.46\'\' En IND.30\'\' Fe IND.24\' e \'Wo IND.3\'\' En IND.42\'\'Fe IND.55\' e a sugerem uma possível afinidade toleítica, ou cálcio-alcalina, para magma original. Os padrões de elementos terras raras revelam fatores de enriquecimento entre 1-10, 50-70, 100-300 em relação à composição condrítica para ortopiroxênio, clinopiroxênio e anfibólio nas rochas estudadas, com fracionamento bem marcado dos elementos leves em relação aos pesados no ortopiroxênio, não observado no caso de clinopiroxênio e anfibólio. Todos os padrões são caracterizados por anomalia negativa bem marcada de Eu. As pressões de cristalização dos magmas foram estimadas entre 1-3,5 kbar, mas os valores acima de ca. 2 kbar possivelmente não tenham significado real, dadas as composições mais ferroanas dos anfibólios. Temperaturas de saturação de zircão e/ou apatita e de equilíbrio entre orto- e clinopiroxênio, anfibólio-plagioclásio indicam intervalos de cristalização entre ca. 1000 e 750° C para as rochas gabro-dioríticas e entre ca. 900 e 670° C para os granitos principais. As paragêneses minerais e os valores obtidos para o número fe# em biotita em equilíbrio com feldspato alcalino e magnetita apontam para condições de cristalização relativamente oxidantes para as rochas félsicas, exceto os álcali-feldspato granitos, e máfico-intermediárias, superiores ao tampão QFM.
The Palermo (ca. 250 km2) and Rio Negro (ca. 130 km2) Plutons crop out in the so called Alto Rio Negro region , Parana state, making part of the Graciosa Province, a NeoProterozoic province (ca. 580 Ma) constituted by granites and syenites in S-SE Brazil. The plutons are made predominant granitic rocks, gabbro-diorites, as well as hybrid rocks constituted mainly by granodiorites. Both plutons show compositional a zoning pattern, which is inversed in the case of the Rio Negro Pluton. The main granitid rocks are mainly metaluminous to slightly peraluminous syeno- and monzogranites with subordinate quartz monzonites and alkcali-feldspar granites. They show a massive structure and a variety of textures, with hb + bi ± all + zr + ap ± ti + mt + ilm as the typical mafic mineral association. Gabbro-dioritic rocks include fine- to medium-grained metaluminous gabro-diorites and quartz monzogabrros and diorites with massive strucure characterized by the mafic mineral associations with cpx ± opx + hb + bt ± ti ± ap ± zr. In these rocks, the plagioclase compositions vary between labradorite and andesine. Hybrid rocks are mainly granodiorites characterized by several strucures and textures indicative of desiquilibrium and mingling/partial mixing between the silicic and basic-intermediate melts that formed the mainn granites and the gabbro-diorites. Such rocks are more abundant in the Rio Negro Pluton. The mafic mineral association is similar, but in contrasted relative abundance, to the ones found in the main granites. In the main granites the amphiboles are Fe-horblende and Fe-edenite, with 0.65 < fe# < 0.95, the higher among these values appearing in the alkali-feldspar granites. Biotite present 0.70 < fe# < 0.99 and the annitic component are also higher in the later rocks. In the case of the gabbro-dioritic rocks, the fe# numbers range between 0.48 and 0.59, 0.41 and 0.56, 0.47 and 0.53 and 0.54 and 0.57 in ortopyroxene, clinopyroxene, amphibole and biotite, respectively. The averaged compositions of coexisting orto- and clinopyroxene are \'Wo IND.46\'\'En IND.30\'\'Fe IND.24\' and \'Wo IND.3\'\'En IND.42\'\'Fe IND.55\' and suggest a tholeiitic or calk-alkaline nature of the original melts. Rare earth element patterns reveal enrichment factors up to 1-10, 50-70, 100-300 relative to the chondritic composition in ortopyroxene, clinopyroxene and amphibole, respectively, with a well marked fractionation of the heavy over the light rare earths in the case of the ortopyroxene, a feature not observed in clinopyroxene and amphibole. All patterns show a notable Eu negative anomaly. Melts crystallization pressures were estimated to be between 1 and 3.5 kbar; however values higher than ca. 2 kbar seems to be unrealistic given the ferroan compositions of some amphiboles. Zircon and apatite saturation temperatures coupled with ortopyroxene-clinopyroxene and amphibole-plagioclase equilibrium temperatures suggest crystallization intervals between ca. 1000 - 750° C in the case of the gabbro-diorites and ca. 900 - 670° C in the case of the main granites. Mineral paragenesis and fe# values in biotite in equilibrium with alkali-feldspar and magnetite suggests relative oxidizing crystallization conditions for the acid and basic-intermediate melts, higher than the QFM buffer, the alkali-feldspat granites being a possible exeption.
