The N–E Tunisian coast (Bizerte region) shows several Quaternary sedimentary archives of middle to late Pleistocene age. Sedimentological analyses carried out (grain size, morphoscopy, exoscopy, petrography, mineralogy, and fossil content) on 12 sections reveal a succession that begins with infratidal deposits attributed to the last Interglacial period, followed by intertidal, continental (palaeosol) and/or aeolian deposits (aeolianites). The arrangement of these deposits, their lithological characteristics and their faunal contents are the basis for a palaeoenvironment reconstruction and estimation of palaeoclimatic conditions. A warmer climate and a high sea level characterize the beginning of this interval, followed by a sea level fall accompanied by an alternation of humid and arid climate. This alternation is reflected by intercalations of the palaeosol levels between the aeolian deposits.

突尼斯东北海岸（比塞大地区）显示出多个中更新世至晚更新世的第四纪沉积档案。对 12 个剖面进行的沉积学分析（粒度、形态学、外视学、岩相学、矿物学和化石含量）揭示了一系列序列，从归因于最后一个间冰期的潮下沉积物开始，然后是潮间带、大陆（古土壤）和/或风成沉积物沉积物（风成岩）。这些沉积物的排列、岩性特征和动物组成是古环境重建和古气候条件估计的基础。这一时期的开始特征是气候变暖和海平面升高，随后海平面下降，伴随着潮湿和干旱气候的交替。
