Sous les pavés la Loire ! Archéologie préventive et occupations précoces de la plaine alluviale à Tours (37)

Abstract : Alluvial plain of the Loire, in the area around the city of Tours (37), has a complex structure. The area is subject to the cross-influences of the Loire and the Cher; it has also long been subject to the dynamics of watercourses that have now disappeared (ruau Sainte-Anne) or have been heavily anthropised over the last century (Dolve, ruau de l’Archevêque). Obtaining absolute dates on alluvial deposits with little or no anthropisation, in levels often located at great depths, highlights the environmental variations to which the pioneer settlements were subjected. For historical periods, the discovery of very recent incisions, as well as the discovery of significant and rapid variations in the dynamics of the Loire system, are part of the understanding of the modalities of urban expansion. Majority of the data comes from rescue archeology, carried out over small areas and without any archaeological discoveries of any significance at first sight. The strong involvement of Inrap collective research has enabled the development of geomorphological themes and their integration into the work of archaeologists. Now, any diagnostic organised in Tours has the status of an operation with high scientific potential, making the notion of a « negative » diagnostic obsolete.
