Zusammenfassung

The geochemical study of two coastal freshwater wetlands was carried out from three percussion well. The relationships of Sr/Al, Na/Al, Mg/Al and S/Al indicate three periods in the last 4000 years in which the salinity conditions were increased, never above mesohaline conditions. These increases in salinity occurred ca 3,700 -2,700 at cal BP to 3,700-2,700 at cal BP, 2,500 or 2,300 at cal BP and 1,600-1,100 at cal B. These periods of increase in salinity coincide with the arid periods recorded in the southern part of the Iberian Peninsula. Thus, it seems that these freshwater coastal wetlands that receive the water supply of Plio-Pleistocene and Mesozoic aquifers may present a good record of paleoprecipitations
