Frisch, Joel A. „Geochemistry, Weathering and Diagenesis of the Bermuda Paleosols:“. Thesis, Boston College, 2020. http://hdl.handle.net/2345/bc-ir:108780.
Pleistocene-age terra rossa paleosols are situated on and are intercalated with eolianite and marine carbonate units across the Bermuda Islands. These clay-rich soils were originally thought to the derived from weathering of the volcanic seamount and/or from dissolution of the carbonate units, the paleosols are now believed to be primarily the result of atmospheric dust deposition from Saharan North Africa and the Sahel via long range transport, with some local inputs. If so, these soil units are mixtures of atmospheric deposition during one or more glacial- interglacial cycles. Previous investigations have been conducted on the paleosols to determine their provenance, age, and to identify unique characteristics for island wide mapping. We conducted comprehensive geochemical analyses to determine the degree of chemical weathering and diagenesis, and to identify processes responsible for their formation and development. The paleosols were found to be geochemically similar across all ages, and to show an increased degree of alteration with age rather than with their duration of subaerial exposure, indicating diagenesis by infiltrating meteoric waters as well subaerial weathering. Evidence of paleosol diagenesis suggests vadose flow across the island may not be limited to preferential pathways and that while flow through the limestones is complex, infiltrating waters appear to have allowed for additional alteration of the soils. In addition to the paleosols, clay-rich deposits with paleosol-like textures were identified during coring operations in Harrington Sound and Hungry Bay, beneath present-day sea level. The source and development histories of these materials were previously unknown. Since these clay deposits are situated beneath present-day sea level it is likely that they were deposited and chemically weathered exclusively during glacial low-sea level climate conditions. Geochemical analyses were conducted on the submarine clay samples to determine if they were related to the above-sea level paleosol and to identify their sources. Major and trace element signatures showed the submarine clay deposits to be chemically similar to the paleosols and to be derived from a similar upper continental crust-like parent. Trace element fingerprinting showed the samples to be derived from a parent similar to that of the paleosols; primarily atmospheric dust with some volcanic contributions. These findings provide additional evidence that trade wind vectors for dust transport were present during Pleistocene glacial climate conditions. Weathering indicators reveal the submarine clay samples to be somewhat less weathered than paleosols of similar age and comparable periods of exposure. Like the paleosols, the submarine clays underwent an initial period of rapid subaerial weathering which suggests warm humid climate conditions during glacial low sea level periods. However, the submarine clays did not experience extended periods of diagenesis, which may explain the somewhat lower degree of weathering. Evidence of inputs from the volcanic platform to the paleosols was limited, but comparisons with shallow volcanic rock and highly weathered volcanic residual known as the Primary Red Clay showed some similarities, suggesting that in-situ chemical weathering of the volcanic platform could produce a laterite with some characteristics similar to the Bermuda paleosols. Geochemical analysis of volcanic sands collected at Whalebone Bay showed the igneous fragments to be a result of mechanical weathering and sorting of heavy refractory minerals and we interpret these sediments to be best described as a beach placer deposit. These materials are enriched in insoluble trace elements and REE, and their contribution to the paleosols is limited

Urupina, Darya. „Uptake and reactivity of sulfur dioxide gas onto Icelandic volcanic dusts“. Electronic Thesis or Diss., Ecole nationale supérieure Mines-Télécom Lille Douai, 2020. http://www.theses.fr/2020MTLD0022.
This thesis investigates the interactions of sulfur dioxide (SO2) gas with Icelandic Volcanic Dusts. Five natural volcanic dust samples were used for the study: Hagavatn, Mýrdalssandur, Maelifellssandur, Dyngjusandur and Eyjafjallajökull. The heterogeneous interactions of gas-phase SO2 with volcanic dusts are investigated using a number of complimentary techniques. Temporal profiles of SO2 uptake and, more precisely, the steady state uptake coefficients have been determined experimentally. These are important kinetic parameters that can be implemented in models. Mechanisms of formation of various surface species resulting from the interactions of SO2 with the surface of dusts are proposed. A new method for quantification of surface sulphur species has been developed and validated. This method can now be used both for further laboratory investigations and in field measurements. It is evidenced that the interactions of SO2 gas with the volcanic dust is a long continuous process. The products formed on the surface are stable and definitely influence the mineral particle properties. It is evidenced that the interactions of SO2 gas and volcanic particles are highly influenced by humidity and by UV light. The influence of surface composition also plays an important role especially at levels of humidity equal or lower than 30% RH. This work emphasizes the importance of using relevant natural dust samples in order to study the heterogeneous atmospheric phenomena involving natural solid particles

Geisen, Carla. „Macro- and micronutrient dissolution from desert and volcanic aerosols in rain and seawater : impact on phytoplankton in the Southern Indian Ocean“. Electronic Thesis or Diss., Sorbonne université, 2021. https://accesdistant.sorbonne-universite.fr/login?url=https://theses-intra.sorbonne-universite.fr/2021SORUS151.pdf.
Aerosols are an important source of macro- and micronutrients for the open ocean. However, only dissolved nutrients are considered bioavailable, i.e. assimilable by phytoplankton. Thus, the quantification of their solubility is essential to (i) estimate the influence of aerosol deposition on phytoplankton, and (ii) closing the biogeochemical cycles of these elements. We thus established the solubility ranges of two types of aerosols (desert or volcanic) according to the deposition mode (dry and wet), by integrating the variability depending on the aerosol origin. Thus, the macronutrient silicon found in desert dust is more soluble compared to volcanic ash (up to 0.7 % against 0.2 %), in particular via the dissolution of quartz. The micronutrient iron dissolves mainly in rainwater during wet deposition of aerosols in the ocean via the dissolution of aluminosilicates, with solubilities generally below 0.14% and 0.02%, in rainwater and seawater respectively, regardless of the type of aerosol. Thus, these results allow a re-estimation of atmospheric nutrients fluxes to the surface ocean which could ultimately be integrated into global biogeochemical models. Finally; the biological response to an atmospheric nutrient input has been determined in the Southern Indian Ocean and the nutrients have mainly benefited the diatom community, especially at the Kerguelen plateau
Dupart, Yoan. „Impact de la chimie des poussières minérales sur la photochimie atmosphérique“. Thesis, Lyon 1, 2012. http://www.theses.fr/2012LYO10292/document.
The objective of this work is to study the heterogeneous processes of mineral dust surfacesunder UV-A radiation. It is know that mineral dust containing metal oxides which can absorbsolar radiation and therefore activate a different chemistry compared to that observed in thedark. In order to avoid measurement artifacts related to the nature of macroscopic films, anaerosol flow tube was developed during this work and applied to study the interactions ofSO2, NO2 and O3 with real mineral dust.An unexpected formation of new particles in the presence of SO2 was observed. In order toexplain this phenomenon, we suggest the desorption of OH radicals from the mineral dustsurface to the gas phase. This mechanism has also been supported by field campaigns.Using real samples of volcanic ash from the last eruption of Eyjafjallajökull in Iceland (2010)allowed us study capture of SO2 on macroscopic ashes films with uptake coefficient around10-7. Associated kinetic experiments combined with chemical analysis allowed us to propose areaction mechanism explaining the formation of iron sulfate on the surface of ashes.Finally, we investigated the photochemical interactions of O3 and NO2 with minerals dustaerosols in the flow tube reactor showing a good agreement with previous data obtained onmacroscopic surfaces

The Kos - Nisyros study area is located at the easternmost edge of the active Quaternary volcanic arc of the southern Aegean Sea and includes the islands of Kos and Nisyros and the islets of Gyali, Strongyli, Pachia and Pyrgoussa. The volcanic activity of Kos island is characterized by Upper – Miocene ignimbrite deposits and Pliocene - Pleistocene volcanic products such as volcanic domes, the Kefalos pyroclastic sequence of hydromagmatic tuffs and the large-scale pyroclastic formation Kos Plateau Tuff (KPT) deposits which is also found on the Kalymnos, Pserimos and Tilos islands. Nisyros is a calcalkaline stratovolcano which consists of Pliocene volcanic products such as andesite and basaltic andesite lavas that are overlain by pyroclastic deposits, lava flows and lava domes of dacitic – rhyodacitic composition. The islets of Gyali, Strongyli, Pachia and Pyrgoussa represent Pliocene lava domes of rhyolitic (Gyali), andesitic (Strogyli) and dacitic composition (Pachia and Pyrgoussa) On these domes, pyroclastic deposits of the Upper Pumice unit of Gyali (in Strogyli) and pyroclastic deposits of the Kos Plateau Tuff (KPT) and Panayia Kyra formation (in Pachia and Pyrgoussa) have been identified. In this thesis, the volcanic products of the Kos-Nisyros area are examined using mineral chemistry, geochemical and petrographical methods, while volcanic structures and morphological features are identified and mapped using remote sensing techniques. The aim of this thesis is to understand the volcanic evolution of the study area, by drawing conclusions regarding the consanguineous relationship of the magmatic products, magma mixing phenomena and the magma chamber system of the area, as well as, the surface expression of this magma chamber system in the form of caldera structures. For this purpose, in this thesis, it is investigated the consanguineous relationship of the Kos Tuff (Kos Plateau Tuff) found on Kos, Tilos and Kalymnos islands, as well as, the geochemical differentiation of the most violent and explosive ignimbrite units D and E of the Kos Tuff, confirming the stratigraphic correlation of these deposits as it was previously presented by physical volcanology data. The petrochemical study of the Kos - Nisyros area as a single "volcanic complex" reveals that the volcanism of the study area is divided into a Miocene and a Pliocene – Pleistocene activity. The Miocene activity is characterized by magmatic and volcanic products such as the monzonite of Kos and the Miocene ignimbrites of Kos and the Pliocene – Pleistocene volcanic activity consists of volcanic products such as lava domes and pyroclastic deposits from Kos, Gyali and Nisyros volcanoes where it is revealed the consanguineous magmatic relationship of these Pliocene – Pleistocene products. Using “Nomarski” interferometry method it is revealed that magma mixing/mingling phenomena are unquestionable for the magma chamber system of Nisyros and provide evidence that these phenomena were active throughout the volcanic evolution of Nisyros volcano. Field observations and remote sensing methods revealed caldera structures in the Kos - Nisyros area which are identified and classified according to new perceptions regarding the volcanic evolution. The volcanic structures of Nisyros volcano are examined using remote sensing methods such as satellite image and digital elevation models interpretation, as well as, the geomorphometric analysis of the Nisyros terrain in combination with geomorphotectonic features of the volcano as presented by other researchers and new perceptions on the volcanic evolution. It is also presented a model of proto-caldera, caldera and post-caldera evolution of Nisyros volcano based on new perceptions on the volcanic evolution in relation to the stratigraphic evolution. Finally, it is studied the subvolcanic magma chamber system of the Kos - Nisyros area, as well as, mixing phenomena in the volcano of Nisyros using the “Nomarski” interferometry method and the distribution of major, trace and rare earth elements revealing the consanguineous nature of these volcanic centers by providing the widest volcanic area of Kos - Nisyros as a major volcanic center characterized by a complex caldera system. Sustainable development of Nisyros volcano represents a management tool which combines the volcanic evolution with the environmental preservation and can promote volcanic regions as geotopes. The investigation of the present conditions of the island reveals, despite the fact that Nisyros is characterized by a strong environmental, energy, social, cultural and economic potential, it remains undeveloped and unexploited due to lack of an integrated sustainable development management plan, based on which, decisions should be equal, equivalent simultaneously and in harmony. Based on the study of the Nisyros water resources, the energy potential from renewable energy sources, the management of natural and urban environment of the volcano of Nisyros and the study of the positive and/or negative effects of the mining industry in Gyali volcanic islet it is proposed an integrated sustainable development according to the views and the perspectives of the local community. From this intergraded plan are generated recommendations for an integrated management of the volcano of Nisyros which satisfy equal, equivalent, simultaneously and in harmony the principles of sustainable development aiming to refocus the local economy, the management of natural and urban environment and the social development.
