摘要：It is therefore the relief in its relationship with petrography. On the valleyof the Arges River, in the mountains sector, the morphology of the area consists ofmetamorphic rocks and it is often monotonous. The differential erosion createsridges and grooves parallel to the schistosity. The shales are soft hollows. Marble andgneiss are resistant surfaces. At a fine scale, the differences favour the destruction ofthe metamorphic rocks. The slope and the deformation of these rocks guide theirmorphological evolution. The presence of the limestones (on small surfaces) reflectsin the relief by specifc forms: avenas, small caves, but also by the specific morphologywhich it imposes to the pre-existent forms of relief (glacial cirques, valleys etc).
