Full textSeismics or Seismology are powerful tools to investigate Earth's crust. However, both rely on seismic waves that travelled through fluid-saturated sedimentary layers. This work, mainly experimental, aims at understanding the static and dynamic effects of the saturating fluid on the elastic response of clastic rocks.In this framework, two specific studies are emphasized:(i) the rock-fluid physico-chemical interaction, often addressed as the "shear weakening" effect, thought to affect the rock overall elastic response; and (ii) the rock-fluid mechanical interaction, addressed as "frequency effect", thought to induce a dependence of elastic properties to the measuring frequency.Two main rock types are investigated: Sandstone and Limestone. All rock samples are chosen to be isotropic and composed of a dominant mineral content, i.e. quartz for sandstone and calcite for limestone

Full textHigh temperature geothermal projects for electricity production are in France mostly localized in the basement of basins linked to the West European Rifting event. The basement of theses basins have been studied on two outcrop analogues at the shoulders of the rift: the Northern Vosges mountains for the Upper Rhine Graben and the Eastern border of the Massif central for the Valence Graben. This study has shown that the fault network is organized in three orders of size with characteristic length and spacing, and that form characteristic structural blocks. The orientation and spacing of these faults and the presence or absence of some size orders are the result of structural inheritance of the basement and the mechanism of the basin opening. The reservoir potential of the basement rocks and the surrounding sedimentary cover has been analysed in light of the fault zones structure and the weathered layer at the top of the basement. Thus, the basement rocks of the basins has been classified in light of the potential of matrix porosity and permeability development in the fault core, the damaged zone and the fractured protolith. The evolution of the fracture network in the fault zone has been studied too, with the development of a double-porosity model in order to characterize the fracture porosity and permeability, and therefore simulate the working of a geothermal doublet in a synthethic fault zone analogue of the geothermal drilling targets

Full textThe early occurrence of intentional heat treatment of silica rocks has recently become a key element in the discussion about the cultural modernity of prehistoric populations. Lithic vestiges are the only sources that remain of this process and the understanding of the material’s properties and transformations are essential for reconstructing the conditions and parameters applied during heat treatment. Several models of the structural transformations upon heating have been proposed in the current literature. These models are often contradictory and do not account for the most recent structural and mineralogical data on chalcedony. In order to propose a new model, I elaborated an experimental procedure, and applied different techniques involving infrared and Raman spectroscopy, solid state NMR, X-Ray diffraction and electron microscopy. The results show that the major transformation to happen is the loss of silanole (SiOH) and the creation of new Si-O-Si bonds according to the reaction: Si-OH HO-Si → Si-O-Si + H2O. This reaction starts between 200°C and 300°C and causes an increase in the hardness of the rocks. The maximal annealing temperature and the ramp rate is a function of the ability of the structure to evacuate newly created H2O and depends on the size of the specimen and the volume of its porosity. These results also show that the annealing duration can be relatively short (< 50 min) for a sufficiently large amount of transformation to be accomplished. The new model allows for the elaboration of a new non-destructive technique for the recognition of heated archaeological flint

Full textSurface and deeper horizons developed in 22 parent materials were sampledin the agricultural and forest soils of Northern France. Total contents of 18 trace elements and two major elements (AI, Fe) were determined in 758 horizon samples, together with the pedological characteristics. Ln the deep horizons, the positive linear correlations of the less mobile trace elements (Bi, Co, Cr, Cu, ln, Ni, Pb, Sn, TI, V, Zn) contents with lutum(particles < 2μm), AI and Fe contents suggest that trace elements are closely associated to alumino-silicates and iron oxi-hydroxides of the finest solid phase. These correlations are close and are common to the deeper horizons of ail the parent materials, whatever their age and type. The processes of the sedimentary rock genesis, including ancient pedogenesis, did not cause any major segregation of the less mobile elements. The mobile elements (As, Cd, Hg, Mn, Mo, Sb Se) show less close relationship with the minerai phase, except Cd and As which seem particularly associated to Mn and Fe respectively. Mercury, Mn and Se show strong links with the organic matter in the deep horizons. Soit parent materials often show an enrichment with the mobile elements. Most of the calcareous rocks are enriched with Cd. Enrichments with ail trace elements, except with Co, Cr and Ni, were found in the surface horizons

Full textThe reconstitution of the thermal history of a sedimentary basin is function of its burial history. The aim of this work is to correlate the information provided by the sequential stratigraphy with the ones provided by the kinetic transformation of the organic matter. The software TherMO'S has been programmed so as to estimate the palaeodepth, paleoporosity, thermal paleoconductivity, thermal paleoenergy and paleoTmax. A constant heat flux is proposed by the user for each borehole and adjusted regarding the Rock Eval pyrolysis Tmax data. TherMO'S has been tested for for 20 of the boreholes of an E-W cross section running from Rambouillet to St Loup in the Paris basin. This study has been realised at the stratigraphic sequential scale. We have obtained a thermal database. The simulations have permitted to point out a lateral decreasing of the heat flux from Rambouillet to Trou Aux Loups. In the mean time, the thermal gradient decrease according to time for each borehole. The thermal results underline the thermal subsidence consequences on the thermal properties evolution associated to each horizon burial history. The simulation permitted to distinguish 3 thermal events during the Pliensbachien, Dogger-Malm and the ending lower cretaceous - upper superior cretaceous

La serie du paleozoique superieur est heterogene et dominee par des lithologies incompetentes ; elle comporte de multiples niveaux de decollements, epais et interstratifies entre les ensembles de nature competente. Un modele geometrique de plissement a pu etre etabli pour ce type de serie ; il correspond a un pli de decollement. Le mecanisme de plissement associe a cette structure est etroitement lie a la geometrie et la nature des corps sedimentaires. Le plissement des ensembles competents s'effectue autour de zones de charnieres fixes par la rotation des flancs, alors que les ensembles incompetents accommodent les variations de geometrie entre deux ensembles competents par fluage et localisent les niveaux de decollements.

Full textThe argilite of Callovo Oxfordien is a sedimentary rock formed in sea water which is made up mainly of quartz, carbonates, argillaceous minerals and various minerals. This heterogeneity of constitution associated with a very low porosity of about 12% confers on argillite a specific behaviour. Indeed this specific behaviour is induced by: (i) of the mechanisms on a microscopic scale of type forces contact with friction for solid minerals quartz and calcite, of repulsion and viscosity for argillaceous minerals and (ii) of the strong interactions between the solid and fluid phases. Thus the conceptual model of the short-term behaviour is proposed while being based on five hydraulic characteristics: (1) two surfaces of loads of the type Drescher & Mroz, associated a pressure of consolidation of 200MPa and a cohesion on healthy argillite, (2) the creation of an anisotropic damage induced by the strains in extension under states of stresses deviators, (3) a distribution of the stress between the solid phases and fluids which uses the coefficient of Biot depend on the maximum damage, (4) a concept of the effective stress for the partially saturated states by calling upon an equivalent pore pressure which depends on the capillary pressure and an average value of the damage and (5) the absence of volumic strains of swelling on healthy argillite. The plastic strain-rates are specified by the non_associative flow rule with the plastic loading surface F and the plastic potential G. On the other hand the behaviour differed from argillite utilizes many mechanisms, chemical, physicochemical and a slip on the scale of the argillaceous layers inducing of the phenomena of viscosity. In the absence of a consensus related mainly to the experimental difficulties and being the subject of current research of the geotechnical grouping of research, one thus proposed a simplified macroscopic model. The introduction of a phase gas into the computer code of finite elements CLEO allowing simulating the transfer of hydrogen. The dealt with problems relate to a standard work cell in direct contact with argillite (without bentonite barrier) with a production of H2 variable in time. These modelling are proposed without heating effect. Lastly, simulations of the saturation of an embanked gallery have the aim of studying the basic phenomena brought into play at the time of the resaturation of a gallery. One proposed a hierarchisation in the processes of simulation by adopting the development of the two conceptual models, one bearing on physics and the other on the numerical aspects. The numerical conceptual model milked space-time introduction of the constituent voluminal elements

Full textMost clastic deposits consist in geometric arrangements of several structures. The purpose of this work is to provide a volumetric representation of these objects in order to reproduce the high heterogeneity of the sedimentary deposits. These models are constructed to be flexible and compact in order to model the sedimentary formations at different scales. The sedimentary models are defined by a boundary representation ; each boundary is defined by a deformable parametric surface. The proposed parametrization is the Non Uniform Rational B-Spline (NURBS). Each elementary shape is controlled by deformation rules and has connection constraints with associated objects, in order to maintain the geometry and the consistency through editing. Sedimentary structure models are applied to channel simulation and to the construction of the related structures such as point bars. These structures are then used as framework for petrophysical property simulations. The models are also applied to semi-automatically interpret geological images by adapting classical shape extraction methods. This approach is applied on satellite pictures showing alluvial channels and some preliminary results on 3D seismic time slices are also presented

Full textMiocene sedimentation, contemporaneous with initial rifting of the Red Sea basin, has been strongly influenced by distensional tectonics. The beginning of the rifting is characterised by normal movements along N140 faults, and strike-slip of N-S and E-W faults. The resulting structural troughs, elongated NW-SE, received continental Miocene sediments of Group A (25 MY); they were supplied by erosion of moderate relief to the Est. Subsequently, all structural directions functioned as normal faults, subsidence leading to marine environments. Two secondary basins are distinguished in the Quseir area. Ln the North the Zarib Basin is characterised by an irregular morphology (horsts and grabens); and a southern Bahari Basin, which subsided earlier, is characterised by the regularity of its morphology. The morphological contrast is directly responsible for differenciation into talus and platform facies. Lnitialy, sedimentation is mixed terrigenous and carbonate (Group B) ; horsts correspond to clearly defined bathymetric highs favouring development of shallow carbonates and these tend to block the transit of silici-clastics sediments. The structural escarpments are overlain by spectacular sedimentary talus. Ultimately, general restriction of the basin lead the deposition of Group C evaporitic which drown the morpho-structural relief. An intense dolomitisation has affected all carbonates

Full textPorphyry 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

Full textMarine source-rocks have heterogeneities both in their distribution and quality over time and space. The deposition of these organic-rich sediments and their variations are complex phenomena resulting from the convergence of several processes which were the subject of many studies. However, the debate on their relative roles and impacts remains strong. The evolution of numerical modelling tools now allows a quantitative approach and new studies about the interaction between these processes. Because of their general context and the presence of several source-rocks, the Lower Jurassic sedimentary basins of Europe are an ideal case to characterize the processes governing the distribution of organic matter (OM). This thesis present the study and the numerical modelling of these basins which allowed to determine the relative influence of the control factors of the OM distribution at various scales. These works bring new elements into the debate about the relative role of these processes. The primary impact of the basin morphology highlighted by these works goes against the dominant literature in which the production and preservation of OM conceal the other factors. Both of these processes obviously play an important role in the distribution of organic-rich layers, but their setting are entirely dependent on the basin morphology. All this work highlights the need to widen the debate for a better understanding of the source rock global distribution, by using the same modelling approach with others organic-rich intervals, others palaeogeographic contexts and for others kind of kerogens

Full textTo evaluate the burial temperature experienced by sedimentary rocks, a wide range of geothermometers is available, based on both organic and inorganic constituents of these rocks. Like all experimental techniques, they show limitations. In this thesis, we used a magnetic approach to estimate burial temperature. In a first part, we studied the magnetic assemblage of selected boreholes over the world to better characterize the magnetic geothermometer MagEval. Two calibrations were established. To assess the relationship between the peak burial temperature experienced by the rocks and their constitutive magnetic minerals, we conducted laboratory heating experiments from 50 to 130°C on unmetamorphosed claystones. The experimental heating showed that nano magnetic minerals are continuously produced with temperature. In a second part, we investigated rockmagnetic properties of sedimentary rocks from two geological plays of petroleum interest : the Grès d’Annot basin in SE France (burial temperature 60-250°C) and the fold-and-thrust belts of the Valley & Ridge Province in the Appalachians, USA (burial temperature _120-200°C). These studies suggested an evolution of the main magnetic minerals with temperature. Magnetite, nanogoethite and pyrrhotite are mainly formed. All the conducted analyses lead us to propose an evolution of the magnetic minerals as a function of the maturity of the rocks and temperature

Full textLes principaux résultats de ce travail sont les suivants :
- Une classification originale des relations entre plis et fractures est établie sur la base d'études comparatives de terrain. La cinématique et les origines mécaniques des différentes associations observées sont discutées, ainsi que de possibles implications au niveau de la dynamique dans les réservoirs plissés fracturés sont proposées.
- Le rôle prédominant de zones de fractures appelées articulations sur l'accommodation de la courbure des plis est démontré par de nombreuses études de terrain. Une typologie de ces zones de fractures est proposée sur la base d'exemples naturels et leur origine mécanique est discutée. L'origine mécanique de ces articulations est précisée dans une étude expérimentale. On utilise des multicouches de paraffine cassante, sollicités dans un dispositif de chargement original. Ce dispositif permet une étude paramétrique des conditions de chargement et de la structure du multicouche, tout en autorisant l'observation en continu de la déformation. Les paramètres les plus importants contrôlant la distribution des articulations et leur évolution géométrique sont la pression de confinement et la friction interfaciale dans le multicouche.
- On présente en outre une étude de cas intégrant l'ensemble des résultats et des concepts. Il s'agit de l'anticlinal de la Montagna della Majella (Italie), qui représente un analogue de réservoir plissé/fracturé.
- Des implications des résultats précédents aux problèmes des écoulements dans les réservoirs sont discutées.
