An integrated study of the interaction between deformation and fluids in a tectonic wrench context (Monts d'Arrée, Brittany, France).
|
|
The Monts d'Arrée is a linear deformation zone with a dominant vertical archtecture, formed during the Variscan orogeny in a tectonic wrench context. The early Palaeozoic siliciclastic sediments have undergone an intense deformation, a.o. expressed as a pervasive cleavage development. In the deformation in low- grade metamorphic conditions fluids play an important role, a.o. in defining the deformation behavior (brittle versus ductile), while deformation exerts an important influence on the migration of fluids (cf. vein development). The research pursues a better understanding of the interaction between deformation and fluids. The research firstly aims at a detailed structural analysis. This analysis consist of a geometrical and kinematic field study of the steep belt, a kinematic analysis of the celavage develop- ment, and a qualitative and quantitative strain analysis. ....
