QUATERNARY SEA-LEVEL CHANGE AND SEDIMENTATION ON THE CONTINENTAL-SHELF AND SLOPE OF ANTIBES, FRENCH RIVIERA

Thin Quaternary sediments overlie Neogene bedrock on the shelf off Ant ibes, southeastern France. Sparker seismic profiles show shelf break p rogradation at 110 m water depth, immediately below the most recent po stglacial transgression. An older progradational event at the same dep th correlates with the top of an acoustically, well-stratified sequenc e on the slope dated at 29.6 ka. Cores show the post-glacial transgres sive surface overlain by shelly sands (dated at 12.7 ka at 85m) and se veral meters of mud. At the present, the seabed consists of an ephemer al cover of fine sand. The data set on sea-level rise complements data recently obtained on land on the Holocene transgression.
