...Hervé Martin Abstract The Saint Malo massif presents a continuous metamorphic series from gneiss to greenschist facies to anatectic granites; in addition, it shows evidence of all stages of progressive melting. A modal and geochemical study shows that incongruent melting of biotite according...

...Jean-Pierre Brun Abstract 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...
