从地球化学、土壤学和孢粉学的角度研究了位于博洛尼亚和意大利北方费拉拉之间冲积平原的青铜时代晚期考古遗址的沉积序列。沉积物地球化学（特别是高含量的铬）表明存在一套薄的宝河沉积物同时代的青铜时代网站，躺在从亚平宁山脉的冲积沉积物。对应于这一时间间隔的土壤的特点也是异常含量的磷和亲铜元素（主要是铜和锌），这显然与人类活动。对研究结果进行了批判性的讨论，以重建地貌和区域古水文环境，支持存在一个未知的埋藏的Po河河道，该河道活跃于中青铜时代晚期的冲积平原南部。14 C和花粉分析证实了这一解释，也提供了线索的成因更浅的泥炭层。总体而言，这一结果为研究南部婆河冲积平原古人类住区的发生提供了新的视角。
A sedimentary sequence comprising a Late Bronze age archaeological site located in the alluvial plain between Bologna and Ferrara (Northern Italy) was studied from geochemical, pedological and palynological points of view. Sediment geochemistry (in particular, the high content of Cr) indicates the existence of a thin set of Po River deposits coeval to the Bronze Age site, lying among alluvial sediments delivered from the Apennine chain. The soil corresponding to this chronological interval is also characterised by anomalous content of phosphorous and chalcophile elements (mainly Cu and Zn) that are clearly related to anthropogenic activities. The results were critically discussed to reconstruct the geomorphological and regional palaeo-hydrographic settings to support the existence of an unknown buried Po River course active during the late Middle Bronze Age in the southern part of the alluvial plain. The14C and pollen analyses corroborate this interpretation, also providing clues on the genesis of more superficial peaty horizons. On the whole, the results provide fresh insights on the occurrence of ancient human settlements in the southern Po River alluvial plain.
