Etude des déformations de la couverture et des bordures sédimentaires des massifs cristallins externes de Belledonne,des Grandes Rousses et du Pelvoux (depuis Les Aravis jusqu'à La région de Remollon). Alpes françaises

Abstract : The aim of this thesis was to study the mechanisms of deformation of the sedimentary cover overlying the Belledonne, Grandes Rousses and Pelvoux crystalline massifs. The work relies on the study of deformation markers as folds, cleavage, fracture, faults and deformed fossils, which allows to evaluate the finite values of the deformation and to understand the kinematics of alpine deformations. The finite deformation is depicted as a succession of tectonic episodes in the context of thrust movements being constrained by inherited structures. Fluid inclusions studies were carry out to evaluate the evolution of the thermodynamic conditions of the deformation through the upper crust.
