Le Dévonien et le Carbonifère inférieur du sud-ouest de la France (Pyrénees,Massif de Mouthoumet,Montagne Noire): sédimentation dans un bassin flexural en bordure sud de la chaîne de collision varisque

Once the post variscan and late variscan motion effect suppressed, one may reconstitute the evolution of the Devonian-early Carboniferous sedimentation domain in the SW of France (Pyrénées-Mouthoumet-Montagne Noire): an extension event at the Silurian-Devonian boundary; — an early Devonian sedimentation period in a basin bordered northward by a shallow-water platform; — an other middle Devonian extension; — a late Devonian-early Carboniferous moderate deepening of the basin floor, preluding a late Visean-Namurian active subsidence characterised by an accumulation of terrigenous Culm deposits. This succession of events may testify for the birth and the evolution of a flexural basin sitting on a continental crust and located South of the variscan collision belt.
