Abstract
Abstract The first results of sedimentologic investigations of Aptian-Albian (Cretaceous) blue marls of the so-called Vocontian trough in the Baronnies region, France, are presented. Their stratigraphic distribution and glauconitic sandstone intercalations are described. The marls appear to have been deposited in shallow epicontinental seas, generally in the open sea, at different depths (mean depth, some hundreds of meters or less); there was no "Vocontian trough." Deposition occurred under reducing conditions and was accompanied at intervals by submarine landsliding and slumping related to oscillations that were responsible for introduction of the clastic elements of littoral origin.
