The lithological study of sediments from a 30 m length core, taken at the western part of the lake of Tunis, combined with the study of benthic macrofauna, helped to identify the different stages of evolution of this ecosystem and the associated climatic fluctuations throughout the period spreading the Tardi Würm (about 42,000 years) to the Holocene. The sedimentological study allowed distinguishing six main facies characterizing different depositional environments. The identification of the mineralogical composition of the Holocene sediments of the upper part of the core, helped to note presence and dominance of two main minerals detected in all samples which are Quartz and Calcite. The determination of TOC contents in samples of Holocene sediments shows the existence of three levels: a surface level with high TOC values (reaching 5.1%), a second level at which values decrease gradually (around 1.1%) and the bottom level with sandy sediment record values <1%.
