Aim. To analyse the marine influences of the Rhenish sea in the distal part of the Swiss Molasse Basin (Jura Molasse) during the Early Oligocene, in order to reconstruct the palaeoenvironmental and the palaeogeographical evolution.Location and geological setting. In the Jura Molasse, the Rhenish sea deposits are mainly preserved in three sedimentary basins: Laufen, Delémont and Ajoie. They...

Located in the distal part of the Swiss Molasse Basin and in the southern extension of the Rhine Graben, the conglomeratic deposits belonging to the Gompholithes & Conglomérats stratigraphic group have been the object of detailed sedimentological and paleontological studies. The great number of outcrops that came into sight during the building works of the Transjurane highway in the vicinity...
