Full textThe Longmenshan Thrust Belt (LMTB), constituting the eastern boundary of the Tibetan Plateau, is well known by its steep topography, intensive tectonic activities and the complicated structures. As a typical composite orogen, the LMTB experienced extensive intracontinental deformation during the Mesozoic. The knowledge on the Mesozoic tectonic evolution of the LMTB therefore is crucial to understand the intracontinental orogeny and uplifting of the Plateau. The vertical cleavage belt divides the LMTB into a Western Zone and an Eastern Zone. The Eastern Zone displays a top-to-the-SE shearing while the western zone a top-to-the-NW shearing. The Eastern Zone can be further divided into four subunits with foliations deepening from SE to NW. The syntectonic granite and published geochronologic data constrain this main deformation to the Early Mesozoic around 219 Ma. Structural analysis, AMS and microstructural study and gravity modeling on the Pengguan complex, one of the orogen-parallel Neoproterozoic complexes located in the middle segment of the LMTB, reveal a basement-slice imbricated structure of the LMTB and adjacent areas. Published ages, localized fast exhumation rate and flexural subsidence of the foreland basin suggest that the basement-slices imbricated southeastwards during Late Mesozoic (166-120 Ma). The LMTB is far away from the contemporaneous plate boundary and devoid of ophiolite-related material, therefore, it is supposed to be an intracontinental orogen. During the Early Mesozoic, the Yangtze basement underthrusted westwards due to the far-field effect of the Paleo-Tethys’ obliteration, and the materials in different structural levels have been exhumated to the surface by southeastward thrusting and contemporaneous backward thrusting. During the Late Mesozoic, the basement is further underthrusted due to the collision between the Lhasa and Eurasia blocks, which led to SE-ward imbrication of the basementslices that may thicken the crust

Full textMargins of large continental plateaus often present significant topographic escarpments, localizing active tectonics and denudation processes. For that reason they constitute a favorable setting for the study of the links between internal and external processes. The main objective of this thesis is to conduct a comparative study of the southern and eastern borders of the Tibetan Plateau: the Himalayas and the Longmen Shan. Both areas present comparable topographic gradients, with contrasting tectonic regimes. The Himalayas are a place of active shortening, associated with the India-eurasia convergence, whereas no significant present tectonic activity can be detected across the Longmen Shan. The quantification of denudation at different timescales in the Longmen Shan allows to balance the classical model proposed for the evolution of this area. In this model the topographic front is actively sustained by lower crustal material flow from the Plateau, toward the foreland. Our data suggests that the evolution of this part of the Plateau is rather controlled by the propagation of a regressive erosion wave toward the Plateau interior on a passive escarpment inherited from earlier deformation stages. The focalisation of erosion at the edge of the Plateau induces a global flow in the crust, toward the foreland. The Himalayas present a significantly contrasting dynamics where the link between tectonic and erosion is inverted with respect to the Longmen Shan case. In opposition to a widely proposed evolution mechanism, our modelling of the dynamics of this area indicates that the localization of erosion is dictated by the structural context, rather than by the repartition of precipitation. The two investigated mountain ranges present contrasting dynamics, where the respective influences of erosion and tectonics are different

Full textLe long de l'orocline des Andes Centrales, sous la Précordillère et l'arc volcanique, la sismicité intracontinentale se distribue en essaims superficiels dont les plus grands séismes (Mw>5.0) ont lieu en général quelques mois après de grands séismes de subduction de magnitude Mw>7.5, déclenchés par le changement de contraintes dû à la période cosismique et probablement post-sismique.
L'analyse d'images et les observations de terrains interprétées conjointement avec les données sismologiques montrent que la déformation de l'orocline est partitionnée dans la Précordillère et l'arc volcanique le long d'une grande zone de cisaillement parallèle à la marge dont la cinématique varie de sénestre au Sud Pérou à dextre au Nord Chili. Le partitionnement observé est attribué à l'obliquité de la convergence et à l'architecture de l'avant-arc et de l'arc volcanique alors que les variations de la déformation le long de l'orocline sont principalement attribuées à la forme de la marge.
L'analyse sismologique, morphologique, et structurale de la déformation indique que le tenseur de contraintes le long de l'arc volcanique est caractérisé par un σ2 vertical et que σ1 et σ3 montrent une rotation anti-horaire depuis le Sud du Coude vers le Nord. En effet, σ1 s'oriente NE-SW au Nord du Chili, NW-SE à l'extrême Sud du Pérou et E-W au sud Pérou.
