Millennial to Centennial Cyclicity Within the Exoreic Saline System of Boujmel, Southern Tunisia

Abstract

Previous works proposed different age models of sedimentation in Sebkha Lagoon of Boujmel leading to the setting of controversial interpretations of eustatic and climatic phases. The aim of this work is carrying out a geological correlation and an astrochronological calibration based on the Holocene cyclostratigraphy leading to the setting of an age model satisfying dates of climatic and eustatic phases identified in southern Tunisia, including the Anthropocene and the Great Acceleration. Along a 130 cm core, four major climatic phases were upward recorded.
