The lack of vertical stratigraphic sondages and open area excavations constitutes a challenge to understanding Mauritanian urbanism. This makes the characterization of the spatio-temporal evolution of Mauritanian towns a difficult task. Systematic excavations carried out in Tamuda by several research teams in the twentieth century provided vertical and horizontal views of Mauritanian urbanism. Our study offers, for the first time, a high-resolution geoarchaeological analysis of Tamuda’s urban sequence (third through first century BC). The microfacies analysis, by means of micromorphology and µ-XRF of Spaces E18 and E20 of the Eastern Quarter revealed a complex interaction of deposits and site formation processes that resulted from changes in everyday urban life. In this respect, the overlap of different construction phases and the alternation of episodes of active use and abandonment is highly significant. This study examines the functional characterization of urban spaces, including the identification of midden activities, a roasting pit, and a milling site (possibly) linked to fish flour production. These activities leave traces on beaten floors and occupation surfaces, and several features indicate abandonment periods between short-term occupations. The result is a complex urban biography of this Mauritanian town, in which human occupation was not constant over time.

缺乏垂直地层 sondages 和开放区域挖掘构成了理解毛里塔尼亚城市主义的挑战。这使得表征毛里塔尼亚城镇的时空演变成为一项艰巨的任务。二十世纪几个研究团队在塔穆达进行的系统挖掘提供了毛里塔尼亚城市化的纵向和横向视图。我们的研究首次提供了对塔姆达城市序列（公元前三世纪到一世纪）的高分辨率地质考古分析。通过微形态学和 µ-XRF 对东区 E18 和 E20 空间进行的微相分析揭示了日常城市生活变化导致的沉积物和场地形成过程的复杂相互作用。在这方面，不同建设阶段的重叠以及积极使用和放弃的交替是非常重要的。本研究考察了城市空间的功能特征，包括确定与鱼粉生产相关的中间活动、烤坑和（可能）碾磨场地。这些活动在敲打过的地板和占用表面上留下痕迹，并且有几个特征表明短期占用之间的放弃期。其结果是这个毛里塔尼亚小镇的复杂城市传记，随着时间的推移，人类的占领并不是一成不变的。和一个（可能）与鱼粉生产相关的碾磨场。这些活动在敲打过的地板和占用表面上留下痕迹，一些特征表明短期占用之间的放弃期。其结果是这个毛里塔尼亚小镇的复杂城市传记，随着时间的推移，人类的占领并不是一成不变的。和一个（可能）与鱼粉生产相关的碾磨场。这些活动在敲打过的地板和占用表面上留下痕迹，并且有几个特征表明短期占用之间的放弃期。其结果是这个毛里塔尼亚小镇的复杂城市传记，随着时间的推移，人类的占领并不是一成不变的。
