Biological evidence of relative sea level rise, during the last 4 500 years, on the rocky coasts of Provence. On the rocky coasts of Provence, biogenic littoral rims develop, built by the coralline Rhodophyte Lithophyllum lichenoides. Remains may be preserved for millenia when submersed in a rising sea environment. These remains can be used as biological indicators of relative sea level variations. The studied stations indicate constant decrease in global speed of relative sea level rise for the last 5 000 years. The Holocene marine transgression seems to stop in Provence around 500 A. D.Les corniches médiolittorales à Lithophyllum lichenoides se développent sur les côtes rocheuses de Provence. Les vestiges de ces bioconstructions peuvent ...
