Based on the climatic phases already recorded in other wetlands, an age model of sedimentation in sebkha-lagoon of Jallabia was carried out to identify the climatic cyclicity. Along an 83 cm core, four major climatic phases were downward recorded. Marine and continental sebkha sensu stricto facies were alternating between 300 yr and 600 yr were interrupted by Anthropocene-Great Acceleration transitions and Holocene-Anthropocene at 70 yr and 300 yr ago respectively. Arid and wet climate alternation within marine sedimentation between 600 yr and 1600 yr. Based on the age model and the spectral analysis, we found a 500 yr cycle. This cycle was worldwide recorded based on geochemical as well as geophysical proxies.
