La zonation structurale des dômes gneissiques. Un exemple : Le massif de Saint-Malo (Massif Armoricain, France)

The Saint-Malo massif provides an example of a gneiss dome with a migmatitic core. The results of a structural analysis are used to describe a structural zonation around the migmatitic core, and a dynamic model of the massif is proposed. A comparison of these results with experimental models of gneiss domes shows that this zonation is the product of diapirism.
