Abstract

Geomorphic and stratigraphic investigations supported by some radiocarbon datings have permitted to approach a reconstruction of the evolution of Mar Chiquita lagoon. The estuarine body originated during the regressive phase that followed the transgressive maximum (about 5000 years B.P.) which led to a relative sea-level stand of 2-2,5 m over present m.s.l. After this maximum, a rapid and minor fall of sea-level coincidental with the development of a Southward-prograding barrier, restricted the estuarine environments which resulted in the formation of the lagoon.
