GEOLOGICAL HISTORY OF THE MORVAN

VARISCAN OROGENY

Part 1

Structure of the Variscan Belt

The Morvan region is located in the NE part of the French Massif Central and in the middle of the central zone of the Hercynian or Variscan Belt. Since the first descriptions [REF], the deep structures of this orogenic belt that extends across Germany, Belgium and France are best described, deduced from seismic profiles [REF], as well as the chronology of the tectonic and magmatic events [REF].

The Variscan Orogenic Belt exhibits a relative bilateral symmetry along each sides of the central zone. Following domains extend from N to S:
