  The Milancovitch Theory explaining the ancient cyclostratigraphy does not file a case for the Holocene cyclostratigraphy. Instead, other astronomical and oceanographic mechanisms control the cyclicity within Holocene sediment. This work aimed to find out the climatic cyclicity along a core from the sebkha of Sidi Mansour located along the Mediterranean coast in Tunisia, through using different proxies: the magnetic susceptibility, carbonate percentages and chemical elements (Ca, Na, and K). Based on previous radiocarbon and tephrochrnological dating in the study area, the core was estimated to cover the two last millennia with a sedimentation rate of 0.35 mm/yr. This rate allows the elaboration of a depth-age model to carry the spectral analysis. Not all the proxies visualize the same climatic cycles. For instance, the spectral analysis of the magnetic susceptibility and Sodium data v.. View More»
