Resumo: 	The carbonates associated with the macrofauna of shallow fine sands have been evaluated at six stations located at five different sites on the French Mediterranean coast. The carbonate content of forty species or zoological groups has been estimated. At each station the mean calcimass has been calculated during a year-long cycle, showing the participation of the different zoological groups, mainly molluscs and echinoderms. The comparison of calcimass and associated biomass shows that CaCO3/AFDW ratio fluctuates between 1.6 to 19.3. These values are similar to those obtained in some rocky bottom communities. Calcimass values usually largely exceed biomass ones; therefore the carbon linked to carbonates cannot be excluded from the carbon balance including macrofauna, which are usually represented only by biomass organic matter. According to mean longevity of species providing CaCO3, the annual carbonate production by macrobenthos in Mediterranean fine sands can be roughly estimated as being one third of its calcimass value.
