Geophysical surveys have been one of the most useful tools for non‐invasive archaeological field assessment. Whereas they have been regularly put into practice at the archaeological site of Santa Margarida (Martorell, Barcelona, Spain), the particular features of the site required a more specific strategy to identify the contact interface between anthropogenic and natural deposits and, therefore, to conclude the archaeological excavation. As the archaeological site is settled on Quaternary alluvia at the confluence of two rivers, and in the absence of built structures in some areas, it was extremely difficult to distinguish between anthropic layers and those silty or sandy natural deposits during fieldwork. Extensive soil survey by means of borehole logging, full‐coring, and Dynamic Penetrometer Super Heavy testing within this site has proved to be a useful strategy to identify the geological horizon and to map the original relief of past landscape before excavation tasks. This enabled us to plan our fieldwork better and to interpret particular features of the site. This paper aims at summarising the results of recent surveys and discussing the potential of this approach for the study of rural settlements and agrarian landscapes in the Middle Age.

通过圣玛格丽达中世纪遗址（马托雷尔，西班牙巴塞罗那）的沉积物建模策略评估自然界与人为界

物探已经成为非侵入性考古现场评估最有用的工具之一。尽管它们已在圣玛格丽达（Santa Margarida）考古遗址（西班牙巴塞罗那，马托雷尔，Martorell）上定期实施，但该遗址的特殊功能需要更具体的策略来识别人为与自然沉积物之间的接触界面，并因此得出结论考古发掘。由于考古遗址位于两条河流交汇处的第四纪阿罗维亚，并且在某些地区没有建筑结构，因此在野外作业期间很难区分人类活动层和那些粉质或砂质自然沉积物。通过钻孔测井，全取心，事实证明，在该地点进行动态渗透仪超重型试验是一种有用的策略，可用于确定地质层位并在开挖任务之前绘制过去景观的原始地势图。这使我们能够更好地计划野外工作并解释站点的特定功能。本文旨在总结最近的调查结果，并讨论这种方法在研究中世纪农村定居点和农业景观方面的潜力。
