Notes:
The Miocene “molasse” of Digne (subalpine chain) is studied in the profile along the Bramefan torrent. Gross lithological and paleontological contents, textures, structures and sole marks are described. All the types of sole marks are present (cf. the Plates), as in turbidites, but they point sometimes to opposite current directions on the same sole. Large-scale (decimeter to meter) cross-stratification is frequent. Graded bedding is very scarce. These observations do not indicate turbidites.These coarse-bedded, well-sorted sediments are interpreted as high-energy deposits. Bird tracks and Mya in living position suggest a beach environment.Some “molasse” formations of Rumania and Spain are then discussed, especially with reference to MANGIN (1962) who shows, near a photograph of the Liedena formation, a picture of bird tracks from Barles: this example comes from the abovementioned Digne molasse, and is not an argument for the occurrence of such tracks in a new “flysch” near Digne.
