Abstract
A major emersion surface (S1) reveals at least a 60-m relative sea-level fall within the 'Calcaires supérieurs' of Grande-Terre (Lesser Antilles fore-arc), an Upper Pliocene-Lower Pleistocene reefal unit. We thus divide the 'Calcaires supérieurs' into 2 units. S1, together with the transgresssive calcarenitic and the Acropora-rich reefal units on top of it, corresponding to the record of a complete eustatic cycle by the carbonate platform of this active margin. A comparison with the carbonate platform of the Bahama Bank stable margin, allows us to relate S1 to the major emersive event of 1.66 Ma and to infer that its origin is glacio-eustatic.
