Dynamique sédimentaire de la lagune de Korba (Nord-Est de la Tunisie)
Abstracts
The Korba lagoon is located at the North-East of Tunisia, it’s separated from the sea by a sandy bar. Its catchment area is consisted of the tertiary and quaternary grounds. The continental and marins contributions of water of the lagoon are occasional (flood and storms). In spite its proximity to sea, the lagoon of Korba is characterized by a semi-arid climate. The sedimentary deposition is mainly detrital. Sands, rich in carbonates, dominate the eastern part is until an average depth of 1 meter. The clayey fraction, witch dominates the lower levels, is rich in carbonates, and the western edge of the lagoon, is poor in carbonates. The carbonates are predominant at the base and miner the top. They are in relation to the accumulation of the shells. This study allowed us to distinguish at the bottom a facies predominantly coastal, characterizing an open environment, and at the top a facies is typically lagoonal, indicating a relatively confined environment.
