Lecerf, Adrien. « Ordre et variation : essai sur le système de Jamblique ». Thesis, Paris, EPHE, 2015. http://www.theses.fr/2015EPHE5071.
Texte intégralThis thesis strives to provide modern research with a synthesis of the system of Iamblichus of Chalcis, an important figure in the development of later Greek metaphysics. It reconstructs in turn his psychology, his hierarchy of being and some of his most basic concepts and philosophical laws, with a stress on the continuity between Plotinus, founder of the Neoplatonic school, and the beginnings of the school of Athens. The whole of Iamblichus’ body of work is exploited, as well as the 800 fragments and testimonia on his life and doctrine handed down to us by later authors. Influences received are analysed and set in context: Plotinus’ and Porphyry’s Neoplatonism, which provides the general levels of reality which Iamblichus tried to analyse and enrich; Middle Platonism, whose topics are debated in Neoplatonism; Aristotelianism, which accounts for a dynamic conception of the human soul and a hierarchy of cognitive powers beginning with the transcendent Intellect; Pythagoreanism, which allows Iamblichus to depict mathematics as a universal language, able to take the mark of all parts of philosophy. By the scope of his work and the originality and neatness of the solutions he provided to problems which nascent Neoplatonism had to confront, Iamblichus is able to create a powerful synthesis which acts as a doctrinal basis for the later schools of Athens and Alexandria: it is profoundly representative of a theocentric era, in which human soul is but a derived principle that has to keep its place in the grand scheme of being. It is a metaphysics of unity, founded on the dual dynamic of order and variation

Texte intégralPorphyry copper deposits (PCDs) are linked to calk-alkaline magmatism produced in a convergent tectonic margin and resulted from the circulation of hydrothermal fluids derived from oxidized and water rich felsic magmas emplaced at shallow depths. During the evolution of the magmatic and hydrothermal systems, the fluid-rock interaction generates typical hydrothermal alteration minerals and can also modify or generates accessories minerals with different properties that can be associated at each stage of the evolution of the system, which could be distinguished by the physico and geochemical characteristics of the inherited accessory minerals (zircon), the modified minerals (apatite) or the newly formed minerals (Fe-Ti oxides). In the Atacama Desert hydrographic basins exposed along the western forearc are filled by gravel deposits which were derived from the erosion of the Domeyko Cordillera in response to the Eocene Incaic tectonic phase. It can be hypothesized that some of these basins contain mineralogical evidences that come from the denudation of porphyry copper mineralized systems located upstream. Therefore, the main goal of this thesis is to find magnetic, mineral and chemical evidences that will help to link the denudation of PCDs with sediments deposited in adjacent basins, mainly by using heavy minerals and magnetic signals as tracers contained in the sedimentary record. To test this relationship, I compare the rock-magnetic properties and physical and geochemical characteristics of minerals (zircon and apatite) in four selected DPCs located in Domeyko Cordillera (Chuquicamata, Mirador, Esperanza and Escodida), with the same characteristics in detrital sediment filling a close basin in the Centinela Mining District. In the studied PCDs, accessory minerals with distinctive physical and geochemical characteristics associated with metallogenic fertility were identified. In zircons, the most fertile samples correspond to these geochemical signatures: Hf > 8,750 (ppm), Eu/Eu* > 0.4, 10.000 x (Eu/Eu*)/Y > 1, (Ce/Nd)/ Y > 0.01, Dy/Yb < 0.3, Th/U < 1 - > 0.1), which can be linked to high oxidation state and high content of magmatic water in the magma. In apatite, the most relevant features indicating fertility are the green luminescence color and high Ca values and low content of trace elements, such as Mg, Na, Cl, which can be related to the evolution of hydrothermal fluids. Although the magnetic signal from DPCs is controlled by the presence of Fe-Ti oxides of hydrothermal and magmatic origin, their characteristics could not be used to differentiate the contribution of these two components. In the stratigraphic record there is a gravel deposit (Tesoro) which contains an important number of zircons and apatite which can be signaled as indicators of metallogenic fertility, that coincides with exotic-Cu mineralization and abundant clasts coming from different hydrothermal alteration zones related to PCDs. In the gravel deposits, a decrease in the magnetic susceptibility values from lower to upper levels is observed, which is mainly controlled by coarse-grain Fe-Ti oxides concentration of detritic origin. In the gravel deposits, rock magnetic properties are mainly controlled by Fe-Ti oxides concentration of detritic origin, where the highest concentration of Fe-minerals could be associated to arid climatic conditions and a rapid tectonically-controlled denudation, whereas the decline in concentration can be related to an aridification trend and/or sources changes

Texte intégralAndré-Mayer, Anne-Sylvie. « Fluides et fracturations dans les gisements de type porphyre et épithermal ». Nancy 1, 2000. http://www.theses.fr/2000NAN10176.
Texte intégralIn metallogeny, it is now obvious that fluids are the main vectors of metals and that fluids and deformations are closely associated in the mineralizing processes. This work deals about this two main aspects in the porphyry and epithermal environment. Fluid studies, realised in the epithermal district of Shila (SW Peru), allow to state a mineralizing model at the district scale. The differences observed in the PVT properties of the fluids seem to explain the different types and styles of mineralization. At Apacheta, studies of the vertical evolution of the physico-chemical parameters of the fluids in parallel to the mineralization show that differences, observed between deep levels (Pb-Zn) and shallower levels (AuAg), is directly linked to a fractionation of gases present in fluids during a boiling event. The geochemistry (crush-leach) of the fluids associated to this type of mineralization in various districts (Shila, Pero; Baia Mare and Apuseni Moutains, Romania; Pongkor, Indonesia) are similar whatever their geodynamic context and are comparable with the fluids associated to geothermal systems. Analyses of fracture networks has been realised at macroscopic scale on different (mineralized or not) vein systems. They allow in a first time to establish a new methodology to characterize paleostresses taking into account the influence of the fluid pressure. Applied on the Soultz-sous-Forêts vein system, this method gives realistic paleostress magnitudes linked to the reopening of quartz veins. The mineralized stockwerk of the Rosia Poieni porphyry copper (Apuseni Mts, Romania) has been chosen for a statistical and hydraulic characterization in order to understand how mineralized vein system evolve and grow. A 1D sampling of the stockwerk has been realized on 2000 fractures distributed on five levels of the open pit (910, 940, 1000, 1045 and 1060 ml. Various statistical analyses has been applied and heterogeneities observed in the stockwerk (metric scale) express directly variations in the copper content. Statistical description of the stockwerk properties seems thus to be a very powerful prospective tool. Estimation of hydraulic conductivities developed by veins has been realized and show equally heterogeneities at the quarry scale. The mean permeability developed by all the veins on each profile decrease from the deeper and more mineralized level (910m) to the highest level (1060m). High permeabilities developed on the 910 m profile are linked to the presence of major drains and the clustered organization of veins. The level 1060 m, characterized by numerous and thin veins with a homogeneous spatial repartition, develop a more pervasive permeability
