Full textIllites clay minerals are very useful in prospection to determine paleo T°-conditions. It has been showed that illite clays are of many chemical compositions and crystallographical structures. Their morphology (hairy, lathy, platy) have a direct impact on reservoirs’ permeability. Nevertheless, growth and nucleating mechanisms of crystallite have not been well identified yet. The aims of this study are 1) the morphological and structural characterization of natural illites (for 4 samples from the Athabasca and Kombolgie basins) with DRX, AFM & MET, 2) to build a theoretical geomorphological model to access to growth mechanisms. First, it appears that illite polytypes / polymorphs are not interstratified in crystals ; the crystal size distributions are very similar whatever the sample. Moreover, a link between morphology and crystalline structure of crystals is established. In the second part of this work, an adapted crystal nucleation model is built to get interfacial strength information and to compare heterogeneous and homogeneous nucleation. An other major results consists in reproducing natural conditions with a thermodynamic model taking into account the morphology of the minerals and their germination site. Such a reconstitution is possible on condition that different kinetical and thermodynamical stability values are defined for each illite polytype / polymorph

Full textLandslides involve many different geological materials around the world. The mechanics and processes controlling mass movements in mountain environment are object of studies and analyses. Landslides occur when the shear strength of a layer in a slope becomes smaller than the shear stress. Various kind of factors can induce this strength variation for example: fluvial action, changes in groundwater level, earthquakes, human activity and also vegetation effects, fault influence, rock and soil properties. This thesis gives an analysis of slope processes to understand how geological, structural, climatic and geomorphological factors are responsibles for instabilities. Liro and Livo catchment basins are the object of this study. They are located in the north-western side of Como Lake, in Lepontine Alps. Several landslides occur in this area. Their study is fundamental to understand the landscape evolution and their impact on the territory. Geological and structural setting of this area is very complex: its relationship with the Insubric Line (and in particular with its brittle branch, the Tonale Line) and the influence on rocks strength are important data to know the triggering area of debris flows and debris avalanches. In particular the Geological Strength Index (GSI) analysis has demonstrated how rock mass behaviour is influenced by presence of structural lineaments more or less conjugated with the Tonale Fault and how this method could be utilized as an indicator of natural failure. The rainfall data show that this area is one of the most rainy zones of the Lombardia Region: the pluviometric analysis involving the calculation of height of rainfall and time of concentration (Tc), have underlined that this regime could induce mobilization of incoherent quaternary cover and trigger landslides. The slope vegetation recovery is an other important indicator for the landslide monitoring because it can give information about the age of the erosive processes. A detailed analysis of three series of aerial photos (1954, 1983 and 1998) have allowed the calculation of extinction and occurrence rates for the analysis of Liro and Livo catchment basins. This aerial analysis and interpretation, in addition to field survey, has shown a high number of landslides classified as debris flows and debris avalanches. A statistical analysis of the Liro and Livo areas and volumes has given the respective limits to understand the potential risk of the area and to estimate the general instability. In fact the volumes mobilized are approximately 450. 000 m3 for an area of 300. 000 m2. A landslide map of Liro and Livo basins has been therefore realized landslide in relation to the lithology (gneiss, limestone, granodiorite, micaschist), deposits (glacial, eluvial, alluvial and paleo-landslides) and erosion processes (debris flow and stream erosion). A landslide inventory is also reported with a brief analysis of the main events divided for sectors (Enclosure A). An analysis of the debris flow in the Inferno Valley, in order to investigate and comprehend the evolution of this process, carried out a topographic survey finalized to morphometric channel measurements, granulometric and geotechnical analyses of the deposits. The study of landslides is not very easy, due to the difficulty in the reconstruction of the topography before the instability. It also hard to determine a relationship between the parameters that characterize a landslide. Analogies between lab-scale experiments and natural events are the input for the creation of a new protocol of analysis of granular mass movement. This experimental investigation has allowed to find out a correlation between principal parameters of a simulated landslide, in particular between runout and the initial slide thickness, initial and critical slopes and between the ratio L/H0 (where L is the runout and H0 the initial thickness) and critical slope. The results promise good evolution: the relationship between zscarp and Lscarp in the experiments is confirmed in Valcirga measures. This geological and geomorphological study has therefore allowed to understand the natural phenomena and the evolution of the mountain landscape strongly affected by tectonic deformation, in relation to the climate change, to acquire ability to analyse these extreme geological events. This study aims to explain if the general assessment of the area can be responsible of instabilities and which factors are involved and their consequences. Ail gathered information will become an important database for further works in the study area

Full textThe tangkuban parahu volcano (2084 m) is a nested strato-cone which developed in the caldera of the sunda volcano in west java (indonesia). It is situated 17 km north of bandung, a city with 2. 5 millions inhabitants in 1995. Sunda-tangkuban parahu is an andesitic volcano belonging to the medium and high alkaline series and is the sole active volcano in the quaternaire volcanic chain, the so-called sunda complex. The geomorphological evolution of this region is marked by the subsidence of the sunda complex, the debris avalanches along the axis of the sunda complex, the plinian/ignimbritic eruptions of sunda-tangkuban parahu, and the reactivation of the west part of the lembang fault. The first event (0. 51-0. 105 ma) formed the basin and the fault scarps of lembang in the south of the complex, but it folded and thrusted up the northern footslopes, forming the mountain, the basin and the broken fold scarps of tambakan. The second event (between 0. 51 and 0. 105 ma, but after the subsidence) left numerous horseshoe morphologies. The third event (about 105 and 50 ka) created the calderas in the summit and the ignimbritic plateaus around the volcano. By these major eruptions, the most part of this region was covered by ash deposits; they are now deeply weathered. The javanesse equatorial climate allows erosion to incise the deposits in the uplands, forming the deep superimposed valleys in the plateaus, and the aggradation in the lowlands, forming the alluvial plains. The fourth event (about 24 ka) uplifted the old fault scarps that were buried by ash and pumice deposits, forming a new one the so-called composite fault scarps. During the 2 last centuries phreatic eruption has predominated on tangkuban parahu. The hazard and the risk of a future eruption are supposedly from phreatic and phreatomagmatic eruptions, but the recurrence of plinian/ignimbritic eruptions is possible. The pyroclastic flows and surges are considered as the most direct hazard

Full textThe Western Kunlun mountain range is a slowly converging intra-continental orogen located at the northwestern boundary of the Tibetan Plateau. Despite evidence of shortening through the range during the Cenozoic, present-day shortening rates are too low to be properly quantified from geodetic techniques. This region has also recorded limited seismicity, but the recent July 2015 (Mw 6.4) Pishan earthquake shows that this mountain range remains seismic. In this thesis, we aim at identifying the structures that actively accommodate this deformation across the range, at quantifying their slip rate and at exploring the potential for major earthquakes in this region.To do so, we first focus on the epicentral zone of the Pishan earthquake. Combining analysis of satellite images and DEMs, we obtain a detailed morphological analysis of the Yecheng-Pishan fold and find nine levels of incised fluvial terraces and alluvial fans. From their incision pattern and using age constraints available on some of these terraces, we are able to quantify the slip rate on the underlying blind frontal ramp to 0.5 to 2.5 mm/yr over the last ~400 kyr, with a most probable long-term value of ~2.0-2.5 mm/yr. Thanks to a structural study of the mountain front based on topographical and geological maps, field observations and available seismic profiles, we also identify a major active thrust sheet forming the deformation front of the Western Kunlun Range. This thrust sheet roots into a shallow decollement that emerges at the surface 150-180 km further north within the Tarim Basin, at the Mazar Tagh ridge. Such important dimensions imply the possibility of major M ≥ 8 earthquakes in the case that the whole decollement is presently seismically locked and fully ruptures in one single seismic event. With the idea of exploring potential along-strike structural segmentation or variations in deformation rate or in kinematics along the mountain front, a morpho-structural analysis is also conducted at the Hotan anticline, located ~100 km east of the Pishan epicentral area, along the morphological front of the Western Kunlun. Here, we build three geological cross- sections and investigate the record of preserved fluvial terraces. Despite a change in the number of active blind structures accommodating deformation, the slip rate remains similar along the mountain front. This pattern may however have been more complex in the geological past. Finally, to have a better understanding on how this deformation is accommodated through this fault system and to further test the possibility that the Mazar Tagh is really structurally and kinematically related to the folds of the mountain front, we conduct a new morphological and structural analysis of the most frontal ramp emerging at the Mazar Tagh ridge. A structural cross-section is built thanks to the combination of a seismic profile crossing the ridge and using field measurements, allowing us to get the precise geometry of the emerging ramp. Despite the current aridity of the region, a set of terraces is identified and sampled in the field for OSL and 10Be dating. Using Pléiades images and derived DEMs, we map theses terraces to quantify the amount of deformation recorded by these markers. This analysis shows that the kinematics proposed is viable and deformation is most reasonably transmitted from the topographic front of the Western Kunlun Range all the way to the Mazar Tagh emerging ramp. We also investigate potential geomorphic markers that may keep a record of past mega-earthquakes at this site of the deformation front. Our results help us get a better knowledge on the structure and kinematics of this range and its deformation front, and to discuss potential seismic hazards in this slowly deforming region

Full textThe formation of orogenic arcs results from several tectonic processes that may have affected the pre-orogenic, pre-collisional tectonic setting, or the collisional tectonic. The formation of the Western Alpine arc is classically attributed to collisional indentation of the European margin and the orogenic prism by the Adriatic indenter. However, the direction of indentation, its rotational component, or the accommodation mechanisms of this indentation are not agreed upon and the numerous kinematic models of the arcuate geometry of the chain are not compatible with one another. The evaluation of the different models of the formation of the Western Alpine arc allows to put forward the probability of the existence of a proto-arc inherited from the subduction phase, and amplified by the Adriatic indentation towards the NW. These two processes explain the formation of the Western Alpine arc, except for its E-W southern termination. Indeed, the orientation of the Castellane Arc seems to be mainly inherited from the Pyrenean-Provençal structures, preceding Alpine collision, and reactivated by post-Tortonian (~12 Ma) N-S convergence, not directly related to Alpine collision. Concerning the WNW-ESE direction of the southern termination of the arc, which forms the Ligurian Alps, it seems to have rotated counterclockwise by 50° with the northern Apennines, linked to the rollback of the Adriatic slab, contemporary with the opening of the Liguro-Provençal basin (23-15 Ma). A compilation of paleomagnetic data in the Alps was constructed and completed with 11 new data sites. The study of vertical-axis rotations, estimated by paleomagnetic analysis refutes the existence of significant rotation of the Adriatic plate during Alpine collision. Oroclinal tests, carried out at several scales, show that the Western Alpine arc develops under the effect of indentation towards the NW from an orogenic prism that is already weakly arcuate before the onset of collision. Furthermore, the European continental margin does not seem to undergo significant rotation, implying propagation of an arc that is mainly inherited from the Mesozoic passive margin. The present geometry of the Western Alpine arc would be mainly controlled by the pre-collisional structure of the European margin that the orogenic prism adopts under the effect of NW Adriatic indentation. Its southern termination would have a different geodynamic history. It would be the result of Pyrenean-Provençal inheritance, reactivated during the Miocene in the External Zone, and of an anti-clockwise rotation of the Internal Zone, linked to the Apennine orogeny. Adriatic indentation, sometimes assumed to follow a westward trajectory, would be accommodated to the south of the arc by a sinistral shear zone of about 50km according to literature. This interpretation is tested by a structural field study, associated with a geostatistical analysis of map trajectories of the schistosity and stratigraphy planes. The results confirm the existence of sinistral shear zones associated with syn-collisional transpressive tectonics. However, these faults seem to represent minor structures with respect to the accommodation of 50 km of displacement. This structural analysis has also highlighted polyphase deformation in the Dauphinois, associated with localised mylonitisation is characterised by a N120° stretching. The assessment of the maximum temperatures by the RSCM method indicates temperatures above 350°C at the northern edge of the Argentera, reaching locally 400°C, corresponding to a regional metamorphism that is more important than the one attributed to this sector of the Alps. This metamorphism is mainly associated with tectonic burial due to thrusting of the internal nappes on the Dauphinois at the beginning of collision. In the Argentera Massif region, the Tmax in the Dauphinois correspond to a burial depth of 11.3 ± 1 km at the level of the Pennine Front, decreasing to 4 km below the Castellane arc

Full textThe northern Tigray (Ethiopia) is characterized by vast plateaus with steeply sloping valleys on their edges. The bottoms of these valleys are now densely cultivated using terraces, water and soil conservation structures. In this mountainous context, archaeological remains from the Aksumite period (1st millennium BCE - 1st millennium CE) have been discovered on Wakarida site. Located on a spur, this small urban settlement raised the question of the relationship between environment, hydro-agricultural facilities and societies. Today, the surrounding valleys are filled by sedimentary accumulations several metres thick, cultivated in terraces. Are these structures the result of the centuries-old transmission of a landscape that could be called "fossil"? The result of the controlled sedimentation undertaken for a long time by the Aksumites and their descendants? The proximity of the structures and of the archaeological remains could suggest this, since the Aksumite culture has similarities with that of the South Arabians, known for their talent in the construction of hydraulic structures.To answer these questions, a systemic methodology was applied. It borrows techniques from geomorphology, geoarchaeology and sedimentology, landscape history and geohistory, and develops ethnoarchaeological and ethno-geomorphological approaches.First, the study of sedimentary accumulations in the valleys of the region makes it possible to highlight the main phases of filling and the various factors controlling detritism, whether biophysical processes (climate change, vegetation cover) or anthropogenic action (deforestation, agriculture). Sediments accumulate from the 7th millennium BCE onwards, under a more humid climate with more regular rainfall than today (African Humid Period). From the 4th millennium BCE onwards, the equilibria changed, leading to the alternation of low and high energy flows. Finally, from the 1st millennium BCE, the influence of human societies became more noticeable in deposits that testify to advanced deforestation from the 13th century AD. No agricultural structure remains were detected in the fillings, which do not result from controlled sedimentation.From the 17th century AD onwards, chronostratigraphic records are missing. Textual and iconographic archives are used to understand the evolution of plant cover and to specify the period of appearance of terraces. They shed light on the position of Wakarida, on the fringes of the Aksum kingdom, following Ethiopian kingdoms and exploration routes. This situation has allowed the persistence of farming techniques over time, some of which date back to the prehistoric period. The only notable exception is the terraces, which are absent from these testimonies. According to the archives, they did not appear in the Tigray until the 1960s.The combination of interviews and archives provides details at the scale of the studied site. The surroundings of Wakarida have recently been repopulated and current structures have been built since the 1990s, in line with agrarian reforms and socio-political events. The terraces of Wakarida reflect the close relationship between economic, social, political and biophysical processes. Their future is now threatened by the regressive erosion that affects the valleys and by the rural exodus that risks breaking the fragile balance between slope, development, cultures and societies.The current structures, which are of recent construction, are therefore based on old fillings that continue to evolve. Thus, the hydroagricultural landscapes of the Wakarida region are not fossil but palimpsest
