| Abstract: | Several mammal remains were recently discovered in the Cornillet gully deposits: Nyctereutes megamastoides, Pachycrocuta perrieri, Dicerorhinus etruscus, Gazella borbonica. Eucladoceros senezensis, Croizetoceros ramosus. This fauna is attributed to the middle Villafranchian.The most recent beds of the Riez-Valensole basin include several superimposed units with three type of facies: fluvio-eolian (i. e. a conglomeratesand-silt sequence), lacustrine and breccian. The Upper Pliocene represented in the Puimoisson-Ségriès region by fossiliferous lacustrine deposits is covered with coarse detrital material. The Cornillet deposits can be found at the lower part of the calcareous formation continuing this Plio-Pleistocene stratigraphy.The breccias of Balène, located at the top ofthese formations, constitute a thick spread of the detrital material of cryoclastic origin. This spread appeared later than the tectonical thrust of the surrounding calcareous mountains upon the Tertiary basin. |
