Повний текст джерелаIn the Early Modern Age (16th - 18th centuries), the construction of ocean-going ships was paramount to the development of cultural encounters in what became the Age of Discovery and European expansion. Spain was one of the biggest forces of that time. The European project “ForSEAdiscovery” seeks answers in this context to the following key questions: Could Spanish forest resources sustain the increasing demand of timber, or were the wood imported from elsewhere? If Spanish forests were not the only wood supplier, how were the trade networks organized? This project will address these questions through a multidisciplinary and innovative training research program to improve the understanding of our historical past, our cultural heritage, and our knowledge of the use of resources for shipbuilding. The objective of this PhD thesis, taking part of this project, is to identify the provenance of the Iberian shipbuilding wood using geochemical tracers. The hypothesis is that trees growing on contrasted rocks and soils have specific geochemical signatures, which can be an indicator of geographic provenance. In this context, the Sr isotopic signature (87Sr/86Sr) was characterized in shipwreck wood samples and wood from living trees, soils and rocks collected from the Spanish forest stands indicated as potential source of wood between the 16th - 18th centuries. The δ88/86Sr signatures were also characterized in the samples. The rock types and ages were characterized at the selected sites and the link between the 87Sr/86Sr and δ88/86Sr in rocks, soils and trees was studied on the sampled Spanish sites. The local signature of Spanish potential sites was determined for provenance of wood. Our results indicate that 87Sr/86Sr isotope ratios in trees reflect the signature of the corresponding soil exchangeable pool while δ88/86Sr was shown to be affected by mass-dependent fractionation with trees taking up lighter (86Sr) isotopes, leaving the soil exchangeable pool enriched with the heavier isotopes (88Sr). This fractionation observed for oak trees, was not found in pines suggesting that the isotopic fractionation during tree uptake is species dependent. The contamination of wood from shipwrecks by seawater elements was identified. Marine Sr was found to be adsorbed on the wood or included in the precipitated minerals in the waterlogged wood. Several extraction experiments were tested and an adapted protocol was developed to extract the seawater elements and retrieve the original signature of the archaeological wood. We succeeded to validate an extraction protocol and retrieve the original signature of one wood sample. This result underline the potential and importance of a new method combining 87Sr/86Sr and δ88/86Sr values for future provenance studies on wood or other materials. However, our results also indicated that most of our shipwreck wood samples did not conserve their original Sr. Therefore, preconizations were suggested in order to extend the use of this tracer in future provenance studies on archaeological wood from shipwrecks

Повний текст джерелаThis PhD thesis examined the mechanisms of storage and release, from and elementary and isotopically point of view, of calcium (Ca) and strontium (Sr) onto or into mineral phases commonly encountered within soils (primary minerals, clay minerals, oxy-hydroxides, pedogenic carbonate). A robust δ88Sr measurements method had to be developed in the laboratory and validated by the measurement of international reference materials, mostly never measured in the literature. The results of this work show that Ca adsorption onto phyllosilicate minerals generates a quantifiable isotopic fractionation by preferential uptake of the light isotope (40Ca) under our experimental conditions when the minerals have a significant structural charge and specific surface area and/or an interlayer space open to hydrated cations adsorption. A study on rhizoliths in natural environment has also highlighted that the combination of Ca and Sr isotopes allows an effective tracing of sources and mechanisms in the problematic related to the storage of these two elements within soils

Повний текст джерелаFor many years, an approach based on the identification of the geographical origin for food product has been implemented through the knowledge of its Sr isotopes, particularly through the analysis of 87Sr / 86Sr ratio. The objective of this thesis is to develop a similar strategy for the olive oils, from the example of PDO Nimes (Gard), in southern France. A specific methodology is necessary since the existing purification protocols of Sr revealed themselves inadequate because of viscosity, high organic load, low Sr content of this matrix In order to proceed to the analysis of the isotopic composition (IC), the first part of the study highlights the definition and validation of a specific method for the treatment of olive oils and strontium purification. The second part of the study is dedicated to expose the processes of assimilation and transfer of strontium into the olive tree. This approach, conducted through a detailed study of one of Nîmes PDO mills, demonstrated that the transfer of strontium from soils to olive tree, and within the olive tree, occurs without isotope fractionation.The last part of the manuscript studies the isotopic ratios 87Sr / 86Sr of the ten PDO olive oils of Nimes and consists in a comparison of this signature with the geological formations underlying the cultivation soils. This approach allows discussing quality of Sr isotopic tool in the geographical recognition of the olive products. The observed similarity between th IC from oils and soil allow us to conclude that, in this context of production, the Sr isotopes are a efficient tool to trace and certify the geographical origin of the oil

Повний текст джерелаTwo types of saline waste were treated by phytoremediation: industrial effluents and marine sediments. The potential of three aquatic species, Phragmites australis, Typha latifolia and Juncus maritimus, to treat the Cl-ion contamination was characterised for different stages of maturity through laboratory tests. These species showed excellent adaptation to saline environments and in particular for a mature growth stage (one-year-old plants). Phytoremediation of the waste considered seems possible with significant reductions, both for effluents (50-95% reduction in 40 days) and solid matrices (5-30% reduction in 80 days). The remediation rates measured in the effluent tests are mainly explained by Cl- ion sorption mechanisms. Plants then play only a minor role via the export of their green matter. A larger scale experiment was carried out on marine sediments dredged specifically for this study. Over the experimental period studied, no plant growth was observed, resulting in no remedial effects. Several causes were identified or presupposed: the granulometry of the sediment (silt), the heat wave of 2019 or the presence of other contaminants (SO42-, metals/metalloids). Nevertheless, these tests have shown that phytoremediation as a single process for managing freshly dredged marine sediments is not suitable. New phytoremediation systems must therefore be studied on these sediments in combination with different processes such as leaching, reverse osmosis or evaporation. Moreover, in order to optimise the epuration capacities of plants in a phytoremediation process, it is necessary to use acclimatised and therefore local species. No method for tracing the geographical origin of aquaculture plants is currently recommended. A tracing tool based on the strontium isotopic ratio (87Sr/86Sr) has been studied in relation to the various frauds that can be observed in this sector. The feasibility of discriminating between geographical areas was assessed by comparing the isotopic signature of different productions throughout the world (France, Germany, Hungary, China). The characterisation of the biogeochemical cycle of Sr for aquatic plants highlighted the major contribution of irrigation water as well as that of agricultural practices, justifying the isotope ratios specific to the productions. The temporal stability of this tool was confirmed through the recultivation of foreign plants in local conditions. Thus, the stable isotopes of strontium are proving to be a valuable tool for certifying the geographical origin of aquatic plants and highlighting the frauds commonly observed in this field

Повний текст джерелаFood authenticity and traceability have received an increasing interest during the last decade since the knowledge of food provenance is regarded as an additional warranty of its quality. The world's globalization brought to the consumers is more and more concerned with the origin of the food they eat because various products are subjected to adulteration or false denomination. The augmentative interest in anti-fraud and consumer protection has led to the extension of scientific research and development of effective tools of food authenticity control. Among the analytical technics applied to food authenticity and traceability, one of the most rapidly developing and promising method is based on fingerprinting of heavy elements detected by atomic spectroscopy. The multicollection inductively coupled plasma mass spectrometry (MC-ICP-MS) is recognized as a method of choice for the high precision measurement of numerous elements of the periodic table as well as ratios of their stable isotopes. This study present a new analytical strategy based on combined non-traditional stable isotopes and trace elements determination by ICP-MS. The benefits of combining information from two isotopic systems, one tracing the soil (Sr), and the other tracing environmental ambient pollution (Pb), allowed to obtain an exceptional new information about traceability and authenticity of selected food matrixes: prestigious Bordeaux wines, dry-cured hams and tea. Using complementary analytical techniques such as traditional elemental fingerprinting, the regional specification, as well as tracing of the food preparation process are possible. When combined with chemometrics, these analytical advances constitute an efficient and promising tool to detect food frauds, including adulteration of high value products with cheaper substitutes, forgery and falsification

Повний текст джерелаIn the eastern Paris Basin, the succession of sedimentary rocks with variable hydro-thermo-mechanical properties leads to a compartmentalization of the system. Three aquifer units - the Middle and Upper Jurassic limestones and the Lower Triassic sandstones - are apart from each other by very low-permeable evaporites and clay-rich successions, among which the Callovian-Oxfordian claystones currently investigated by the French national radioactive waste management agency (Andra). This PhD thesis deals with the thermal history reconstruction and the fluid-rock interactions in the Mesozoic series through a multidisciplinary approach. In the first part of the manuscript, the P-T evolution of the Mesozoic series is documented based on thermal indicators (vitrinite reflectance, biomarker isomerization, fluid inclusions) and numerical modeling. In the second part, major and trace element concentrations (including REE) and isotopic compositions (d18O, d13C and 87Sr/86Sr) of authigenic minerals and fluid inclusions were used to estimate the origin of paleo-fluids and their evolution through water-rock interactions. In the Lower Triassic sandstones, K-Ar dating of authigenic illite documents two periods of crystallization at 179.4 ± 0.8 Ma and 149.4 ± 0.3 Ma

Повний текст джерелаWe are evaluating strontium and stable lead isotopes, anionic tensides and TBT as an alternative tracers of landfill leachate in groundwater. The municipal landfill studied here is located in south-eastern France. Based on the evaluation of chloride concentration, the plume extends a maximum of 4600 m. Strontium and lead isotopic composition characterizes two sources : natural groundwater and landfill leachate contamination. Evolution of mixing ratios obtained with strontium reveals a second source of groundwater contamination : fertilizers (87Sr/86Sr = 0. 707859). These results suggest that isotopic signatures can be used to provide useful information on sources of groundwater contamination where conventional water quality parameters may yield ambiguous results

Повний текст джерелаChanges in geochemical and physical properties of speleothems are considered to be accurate proxies of climate variability. However, the climate signal is modified by the internal dynamics of the whole karst system. The aim of the research was to obtain reproducible data extracted by established and non-conventional techniques from two coeval speleothems removed at Grotta Savi cave (Italy), to gain information about regional climate responses across the Last Glacial Maximum to Holocene transition. Different past hydrological regimes for the two stalagmites’ drips were reconstructed on the basis of stalagmites’ physical characteristics and this helped to disentangle the global from the local phenomena. This non-conventional approach, was applied here for the first time on fossil sample, resulting in a benchmark for interpreting the chemical proxies, and enabling assessment of calcite formation environment, hitherto not possible. The interpretation of δ18O values as reflecting past hydrology was then validated by using the Hydrology Index. The Index, developed in this study, considers two independent proxies: the Mg concentrations and the fraction of Sr uptake that is not dictated by growth rates. The method allowed recognition of a non-hydrological component encapsulated in δ18O values, then interpreted as changes of air mass provenance and rainfall seasonality. The δ13C was chiefly driven by temperature-dependent soil respiration rate. However, a hydrological component was also detected in the δ13C by using dead carbon proportion (dcp) and 87Sr/86Sr ratios. Increases of 87Sr/86Sr ratios suggest increases of aeolian dust deflated from proximal subalpine periglacial regions facilitated by vegetation-cover reduction, soil destabilisation and windier conditions, which in turn enhanced drier conditions. Although, the dcp trend was likely related to a local, faster, soil organic matter turnover, enhanced by warmer conditions, episodes of high dcp values were possibly hydrologically induced, as a result of wetter conditions. Furthermore, the Hydrology Index and δ13C signal allowed reconstructing that wet conditions occurred during climate cooling, an improvement relative to the state of the art of δ13C interpretation, where more commonly wet conditions occurs during warming. The comparison of δ13C trend of Savi with another stalagmite with similar physical characteristics, but from a cave (Sofular) located in Turkey, revealed a common trend despite the impact of the last glaciation having been drastic at Savi (no speleothem growth). Such δ13C similarity could be related to global phenomena and point to an intriguing possibility, which needs future testing, that speleothems may encode information of the C cycle, similar to soil carbonates. The palaeoclimate interpretation extracted from the Savi records between 15 to 9 ka indicates that the Younger Dryas (YD) was a dramatic climate reversal. In the northern Adriatic, the YD is characterised by high hydrological variability, strong winds and a cooling, which resulted in a decrease of vegetation cover and increase of soil erosion. The wind regime was possibly orographically induced, with the Alps acting as a barrier, deviating westerly winds and causing increased windiness in the northern Adriatic region. The Savi records reveal a significant Early Holocene anomaly (10.4 ka), whose drier and colder conditions were probably amplified by a local synoptic framework.

The relationship between global climate change and continental weathering is a cause-consequence feedback system. Global climate may be perturbed by any of processes controlling weathering through changing atmospheric CO2 abundance, and in turns to further affect the extent of weathering. In this iteration, the atmospheric CO2 fluctuation is controlled by the stoichiometric balance between the CO2 consumption by silicate mineral weathering and CO2 release by marine carbonate precipitation at long-term time scale. Thus, discriminating the terrestrial weathering sources from silicates and carbonates, and determining the extent of weathering are important and the fundamental knowledge for comprehending the long-term climatic evolution. In chapter 1, the application of newly triple Sr isotopes, 87Sr/86Sr and δ88/86Sr ratios, was introduced and suggested to serve as a powerful isotopic tracer, rather than the 87Sr/86Sr alone, for simultaneously determining the continental weathering fluxes to the ocean and quantifying the Sr burial flux by the carbonate precipitation in the marine system at glacial and interglacial climatic cycles. Given that rivers are the largest Sr source to the ocean, however, there were only few attempts available for studying relevant controls on δ88/86Sr fractionation in riverine waters. In order to have confidence in interpretation based on the recent developed isotopic proxy, the following questions should be therefore clarified by the first order: (1) The variability of δ88/86Sr for lithological specimens, i.e. silicates and carbonates. (2) Potential physicochemical processes that controlling the δ88/86Sr fractionation in terrestrial environments. (3) Lithology and/or fractionation control the variability of δ88/86Sr in riverine waters. To address those fundamental questions, the following chapters provide a comprehensive evaluation of stable Sr isotope fractionation during continental weathering processes by natural specimens and laboratory experimental works. In chapter 2, we demonstrated a highly precise and accurate δ88/86Sr determination by using multiple-collector inductively coupled plasma mass spectrometry (MC-ICP-MS) with empirical external normalization and standard sample bracketing (EEN-SSB) method for mass bias correction. In this chapter, we evaluated the fractionation behaviors of Sr and Zr isotopes during MC-ICP-MS determinations and established a modified procedure to apply 92Zr/90Zr instead of currently available 91Zr/90Zr for Sr isotopic mass bias correction. A factor of 1.5 was improved in precision of our δ88/86Sr determination that is likely owing to the smallest instrumental mass-independent fractionation between the isotopic pair of 88Sr/86Sr and 92Zr/90Zr. This new method allows 87Sr/86Sr and δ88/86Sr ratios to be measured simultaneously with high throughput and comparable precision and reproducibility with double spike (DS) applied MC-ICP-MS δ88/86Sr determinations. In chapter 3, to evaluate the potential processes lead to δ88/86Sr fractionation during silicate mineral weathering, an intense pedogenic paleosol sequence was sampled in the Chinese Loess Plateau (CLP). Sequential extraction procedure was applied to isolate different geochemical phases of the soils to study the stable Sr isotopic distributions in the extracted exchangeable, reducible and silicate fractions. The results suggested that heavier δ88/86Sr was preferentially released during incongruent silicate mineral weathering. This is further evidenced by the acid leaching experiments using the soil silicate phase, primary silicate minerals and clay standards. In chapter 4, an annual time-series monitoring of chemical and Sr isotopic compositions on a carbonate-dominated catchment was performed to evaluate the influences of secondary calcite precipitation and silicate mineral weathering on water δ88/86Sr. A seasonal systematic of karst cave stream water δ88/86Sr was detected showing coherent heavier δ88/86Sr and radiogenic 87Sr/86Sr ratios detected in the warm and rainfall period reflecting enhanced biological activities and intensive silicate weathering at that time. On the other hand, at least 30% to 55% of Ca was removed by the secondary calcite precipitation and lead to 0.1‰ heavier in water δ88/86Sr. Those time-series data emphasizes the critical role of secondary calcite precipitation on the comprehensive heavy δ88/86Sr ratios in waters draining carbonate-dominated catchments, and peak of related heavy δ88/86Sr ratios by intensive silicate weathering in wet season and extreme rainfall events. In chapter 5 (conclusion), we compile all the currently published stable Sr isotope data from literature sources (2006 to early 2015) and this study for evaluating the potential mechanisms controlling the sensitivity and variability of δ88/86Sr of the continental weathering flux to the ocean and its implication for global Sr cycling. The data suggests that the variability of δ88/86Sr of the terrestrial silicate materials and carbonates are statistically lighter than that of riverine waters. In stead of lithology, fractionation of Sr stable isotopes during and post-weathering processes, such as secondary phase precipitated, incongruent silicate weathering, and vegetation uptake, might be more important factors and by the first order lead to the enrichment of heavy δ88/86Sr in the waters. The degree of δ88/86Sr fractionation in continental weathering environments may have significant implications to the oceanic Sr isotopic budget at glacial-interglacial time scales. The variability of δ88/86Sr in modern rivers will still need to be better constrained for studying the global Sr cycling at geological time scales.
