Abrupt climatic variability since the last interglacial marine isotopic stage 5E recorded in the coastal sediments of southeastern Tunisia


, : Abrupt climatic variability since the last interglacial marine isotopic stage 5E recorded in the coastal sediments of southeastern Tunisia. Comptes Rendus de l'Academie des Sciences, Serie II Sciences de la Terre et des Planetes

We have compared the sedimentological record of the Pleistocene coastal deposits in southeastern Tunisia with the climatic data obtained on two deep-sea cores recovered in the Mediterranean Sea. Coastal marine deposits are composed of two distinct lithostratigraphic units separated by an erosion surface. The radiochemical dating shows that these two units were developed during the unique marine isotopic substage 5e (the Last Interglacial). The lower unit mainly consists of quartz-rich sands whereas the upper one consists of carbonate deposits. This petrographic contrast indicates that the palaeoclimatic evolution in the southeastern coast of Tunisia was identical to that observed in the western Mediterranean Sea and the surrounding continents. In particular, the establishment of humid conditions at the beginning of the Last Interglacial was responsible for a supply of terrigenous material and siliciclastic sedimentation along the coastal area of southeastern Tunisia, whereas the regression of these wet conditions during the second half of the Last Interglacial favoured carbonate sedimentation.

Porosity is possibly an important parameter with respect to leaching of constituents from cement monoliths. During its lifetime, the pore structure of cementitious matrices changes due to carbonation and leaching. This paper discusses the effects...
