Texto completoClimate change has recently become a major concerning among scientists and the general public. A better knowledge of past climates helps forecasting the future evolution of climate. Stable water isotopes stand as an outstanding paleo-climate proxy. Physical properties of heavy stable water isotopes (H182 O; HDO) cause fractionation processes related to temperature and degree of distillation. If the isotopic signal is correctly inverted, past climate change can be inferred from isotopic archives. Andean ice-cores offer a unique records of tropical climate and its variability through time. However, the interpretation of the isotopic signal is difficult because of complex atmospheric dynamic over South America. For this purpose, we developed a module handling the stable water isotope fractionation processes within the regional circulation model REMO and applied it to South America. The manuscript outlines the major milestones of the present PhD. We first introduce the research topic in the wider scope of climate change; the description of the stable water isotope enabled regional circulation model REMOiso; an initial validation of REMOiso over Europe; an investigation of the seasonal variations of precipitation, atmospheric circulation and isotopic signal over South America; and at last the recording of the south American monsoon system (SAMS) by stable water isotope diagnostics

Texto completoLCT-type rare-element pegmatites have long been studied and exploited for their gems and rare metals they contain. Despite many studies about the rare-element enrichment, or about the mechanisms leading their exotic textures, very few studies have been dedicated to the mechanisms controlling their emplacement and their spatial distribution at the scale of the pegmatite field. To better investigate the origin of ascent-driving mechanisms of these magmas, a multidisciplinary study was conducted on 3 rare-element pegmatite fields across the Variscan belt. The results demonstrate the spatial proximity of the rare-metals-rich pegmatites with the intensity of deformation of the hosting rocks. In addition, spatial statistical analyses suggest that the emplacement of such magmas has been facilitated by fracture-controlled model. According to numerical models, the rise of these pegmatite-forming melts along weakened crustal zones would be facilitated by their peculiar physico-chemical properties (low viscosity and density), but also by very high crustal permeability (> 10⁻¹² m²) at depths around 10 km. Finally, accordingly to Li isotope signatures measured on pegmatitic micas, lithium does not fractionate from neighbouring granite up to the more differentiated pegmatites, since all δ⁷Li (‰) fall within a range of - 2 to + 2 ‰, as for orogenic granites. Therefore, we suggest that the genesis these pegmatite-forming melts is common to that of peraluminous granites. Mechanisms of fracturation and magma-pumping may have favoured the rise of these low volumes of residual melts, enriched in rare-elements, during short periods (~ 10³ yrs) of strong permeability increase. These results question the granitic model commonly used for the exploration of this type of mineral deposits. We suggest a revisited model accounting for both genesis and emplacement controlling mechanisms of the pegmatite-forming melts

Texto completoPrimary smelting slags, known as Lead Blast Furnace (LBF) and Imperial Smelting Furnace (ISF), were generated by the former pyrometallurgical industries located in Noyelles-Godault, Northern France. Following its closure in 2003, 4 million tons of primary slags have been landfilled as a heap in the vicinity of the Deûle River, near the industrial basin of Nord-Pas-de-Calais. These slag materials are often enriched in particular metals (Pb, Zn) that can be released into the environment through alteration processes and leaching. Many biological and chemical processes might take place within these tailings and thus affect significantly the slag weathering. Predicting the environmental impact of these wastes requires an understanding of the mineral-water interactions as well as the influence of the biological activities (the involvement of microorganisms). Thus, this research is designed to simulate the natural weathering of slag by simulating different weathering conditions with or without the involvement of the microorganisms as well as by varying several chemical parameters. Chemical weathering of both LBF and ISF slags was studied by as a function of pHs (4, 5.5, 7, 8.5 and 10) as well as under two atmospheres (open air and nitrogen). Significant amounts of Ca, Fe and Zn were released under acidic conditions (pH 4) with a decrease towards the neutral to alkaline conditions (pH 7 and 10) for both slags. The concentrations of all elements increased gradually after 216 h compared to initial 24 h of leaching period. The presence of oxygen under open-air atmosphere not only enhanced oxidative weathering but also encouraged formation of secondary oxide and carbonate phases. In addition, Zn dissolution was related to extremes zinc isotopic signatures in the leachate; heavier δ66Zn values at low pH than at high pH for both slags under open-air atmosphere. On the other hand, bioweathering of both slags was studied in the presence of a pure heterotrophic bacterial strain (Pseudomonas aeruginosa) in a bioreactor operated in batch conditon as well as in a semi-flow through reactor with intermittent leachate renewal conditions. P. aeruginosa is shown to play a significant role in slags weathering by enhancing the leaching and solubility of Zn and Pb. In addition, the cumulative bulk release of dissolved Fe, Si, Ca and Mg doubled in the presence of bacteria, probably due to the release of soluble complexing organic molecules (e.g. siderophores). Bacterial biomass served as the bioadsorbent for Pb, Fe and Zn as 70-80% of Pb and Fe, 40-60% of Zn released are attached to and immobilized by the bacterial biomass. Oxides, hydroxides and carbonates were predicted as secondary phases during chemical weathering of slags whereas carbonates and phosphates were dominant phases during bioweathering. These predictions were in agreement with the observations by Scanning Electron Microscopy (SEM) with Energy Dispersive X-Ray Analysis (EDS), Transmission Electron Microscopy (TEM) analysis, and X-ray Photoelectron Spectroscopy (XPS) analysis

Texto completoThis research has the hypothesis that debris flows are the major processes related to landforms evolution of the Serra do Mar (SP), and we expected therefore a direct relationship between long-term denudation rates and higher magnitude debris flows events, which is strongly controlled by drainage basin morphometry. We believe that morphometric characteristics, fundamental to drainage basins hydrological dynamics, are determinant to debris flows initiation and propagation in humid tropical environments. Thus this research aims to verify the relationships between debris flows magnitude, basin morphometry and long-term denudation rates in escarped reliefs such as Serra do Mar. Therefore, specific goals are: (i) evaluate the potential to debris flows generation; (ii) evaluate the relationship between drainage basin morphometry and debris flows magnitude; (iii) discuss long-term landforms evolution from denudation rates at drainage basin scale and; (iv) evaluate the importance of debris flows like the main exogenous processes to landforms evolution in passive margins in humid tropical environment. The procedures adopted to the research development were: (i) selection of drainage basins; (Ii) alluvial sediment sampling; (Iii) mapping debris flows deposits; (Iv) application of morphometric parameters; (V) application of Dimensionless Indices to measure the potential to debris flow generation; (Vi) sample preparation and analysis of 10Be concentration; (Vii) integrated analysis of the results. The basins have morphometric characteristics which gives them high erosive power, as the high Ruggedness Index and Relief Ratio. From the Dimensionless Indices application, the basins classified with higher potential to debris flows generation were Rio Claro 1 and Massaguaçu. The identification of superficial debris flows deposits and boulders size subsidized the classification of five basins with higher magnitude and five with lower magnitude. Long-term denudation rates ranged between 10.9 m/My and 35.2 m/My, averaging 25 m/My. We observed that lithological variations, fractures and folds could explain better rates distribution, instead of morphometrics characteristics of drainage basins. We believe that high long-term denudation rates for some basins with lower magnitude indicates that such processes would be the main processes for the geomorphological work and consequently for the long-term evolution of the Serra do Mar (SP).
