Abstract The prehistoric settlement of the west coast of the Senegalese-Mauritanian basin is established from archaeological remains and coal samples collected, sometimes in a stratigraphic context. However, the chronology issued, in the Before Present (BP) age, does not take into account the taphonomic context of the sites and the local reservoir age. Therefore, this article revisits the chronologies obtained based on the 14C literature and dating(s) acquired. Changes in time and duration of human occupancy of the area are shorter or longer depending on adequate yields of local reservoir age (Ndeye, 2008), which is a relevant element for marine samples. Thus, the archaeological implications observed with the reservoir effect are the rejuvenation or ageing of the dates, the age of the sites, the duration of occupation prehistoric or historical sites studied. Using the calibration programmes, it is noted that for the site of Senegal (Khant), without taking into account the reservoir effect, the human occupation is a priori, from the fifth millennium (Ancient Neolithic) to the third millennium BC (Middle Neolithic). However, if this marine reservoir effect is applied, the chronological periodisation goes from the fourth millennium to the first millennium. For the Mauritanian sites, the reservoir age correction is necessary for the Chami site while for the Tintan site is not required. Therefore, the calibrated archaeological chronologies obtained after the application of the marine reservoir effect are more relevant.

通过使用海洋水库年龄校正来修订塞内加尔和毛里塔尼亚遗址的人类职业年表

摘要 塞内加尔-毛里塔尼亚盆地西海岸的史前聚落是根据考古遗迹和收集的煤样建立的,有时是在地层背景下。然而,在现在(BP)时代发布的年表并未考虑遗址的埋藏背景和当地水库年龄。因此,本文重新审视了根据 14C 文献和获得的年代学获得的年表。根据当地水库年龄的充足产量(Ndeye,2008 年),人类在该地区居住的时间和持续时间的变化会更短或更长,这是海洋样本的相关要素。因此,通过水库效应观察到的考古意义是日期的复兴或老化,遗址的年龄,研究的史前或历史遗址的职业持续时间。使用校准程序,注意到对于塞内加尔(Khant)遗址,在不考虑水库效应的情况下,人类职业是先验的,从第五个千年(古新石器时代)到公元前第三个千年(新石器时代中期) . 然而,如果应用这种海洋储层效应,时间上的分期将从第四个千年到第一个千年。对于毛里塔尼亚的场地,查米场地需要进行水库年龄校正,而丁坦场地则不需要。因此,应用海洋储层效应后获得的校准考古年代学更具相关性。不考虑水库效应,人类职业是先验的,从公元前五千年(古新石器时代)到公元前三千年(新石器时代中期)。然而,如果应用这种海洋储层效应,时间上的分期将从第四个千年到第一个千年。对于毛里塔尼亚的场地,查米场地需要进行水库年龄校正,而丁坦场地则不需要。因此,应用海洋储层效应后获得的校准考古年代学更具相关性。不考虑水库效应,人类职业是先验的,从公元前五千年(古新石器时代)到公元前三千年(新石器时代中期)。然而,如果应用这种海洋储层效应,时间上的分期将从第四个千年到第一个千年。对于毛里塔尼亚的场地,查米场地需要进行水库年龄校正,而丁坦场地则不需要。因此,应用海洋储层效应后获得的校准考古年代学更具相关性。时间上的分期是从第四个千年到第一个千年。对于毛里塔尼亚的场地,查米场地需要进行水库年龄校正,而丁坦场地则不需要。因此,应用海洋储层效应后获得的校准考古年代学更具相关性。时间上的分期是从第四个千年到第一个千年。对于毛里塔尼亚的场地,查米场地需要进行水库年龄校正,而丁坦场地则不需要。因此,应用海洋储层效应后获得的校准考古年代学更具相关性。
