The geological evolution of NE Corsica

Abstract

A geologically mapped and investigated transect through NE Corsica is subdivided into its main tectonic units. The zone of the 'schistes lustrés' s.s. is overlain by two ophiolite units: the upper one shows no or weak metamorphism and has an eastern origin; it has overthrusted the metamorphic lower ophiolite unit and the 'schistes lustrés' zone s.s. in a westerly direction. Blueschist metamorphism is confined to the overridden 'schistes lustrés' zone, the lower ophiolite unit and small parts of the Hercynian basement.
