Cette "société savante" a regroupé amateurs et professionnels et a permis la publication d’une somme d’informations, notamment dans son premier volume consacré au Paléolithique des deux départements haut-normands (1894). Cette tradition s’est perpétuée, tant pour la recherche géomorphologique que pour la préhistoire ancienne, comme l’atteste la thèse de François Bordes (1954). Tous ces travaux ont livré un abondant mobilier lithique souvent trié et collecté dans les briqueteries. Ce matériel, conservé pour les séries anciennes au Musée d’Évreux, a été révisé. Parallèlement, les travaux d’aménagement de l’agglomération ébroïcenne ont livré deux sites paléolithiques : l’occupation azilienne des "Bas-Fayaux" à Évreux et les vestiges du Paléolithique moyen récent de Parville. La création du parc d’activités du Long-Buisson a fait l’objet d’un diagnostic qui n’a livré que quelques vestiges paléolithiques dispersés dans la stratigraphie, ne motivant pas une prescription de fouille. Cependant, les décapages effectués sur les emprises de fouilles prescrites concernant les périodes protohistoriques et historiques ont révélés plusieurs niveaux d’occupations associés à des phénomènes karstiques. Les principaux résultats sont issus de ces investigations conduites sur le site entre 2001 et 2003, tant au plan des contextes environnementaux, que des problèmes de conservation des niveaux anthropiques (plateau karstifié) qu’à la préhistoire ancienne. De ce fait, le site du Long-Buisson participe largement à une meilleure connaissance des peuplements de l’Évrecin et par extension de Haute Normandie. L’essentiel de la matière première mise en œuvre au LongBuisson est issue de l’argile à silex qui tapisse le plateau. La matière est d’une qualité inégale et les états de surface semblent dépendre de conditions locales d’enfouissement différentes. Research concerning the Upper Palaeolithic in Upper Normandy goes back to the beginning of the XIXth century and had been largely supported by the Société normande d’études préhistoriques, created in 1893. This ‘learned society’ regrouped amateurs and professionals and encouraged the publication of a large amount of information, notably in the fi rst volume dedicated to the Palaeolithic of the two departments comprising Upper Normandy (1894). This tradition continued, as much for geomorphological research as for Early Prehistory, as attested in the thesis of François Bordes (1954). All these investigations brought to light an abundant quantity of lithic artefacts, which were often sorted and collected at that time in brickworks. This material, part of the early collections of Évreux Museum, has now been restudied. At the same time, recent development within the agglomeration of Évreux brought to light two Palaeolithic sites: an Azilian occupation at ‘Bas Fayaux’ near Évreux and Middle/Late Palaeolithic remains at Parville. The creation of an industrial estate at Le Long-Buisson necessitated the realisation of an archaeological evaluation which revealed only a small number of dispersed Palaeolithic remains, which it was considered not to merit any further investigation. However, topsoil stripping carried out on the areas concerning the Protohistoric and Historic periods revealed several occupation levels associated with karstified phenomenon. The principal results come from the investigations carried out on the site between 2001 and 2003. They were concentrated as much on the environmental aspects as on the problems concerning the conservation of anthropic levels (karstified plateau) and those concerning Early Prehistory. Therefore, the site of Le Long-Buisson makes an important contribution towards our better comprehension of human settlement in the Évreux region and more widely that of Upper Normandy. Most of the raw materials that used at Le Long-Buisson come from the levels of clay with flints that cover the plateau. The material is of unequal quality and their condition depending on local burial conditions.

Samples of OIS were analyzed and characterized by X-ray diffraction (whole rock and clay fraction), LA-ICP-MS, HH-XRF and PIXE. Ironstone objects from Colombelles (early Neolithic) show compositions that are different from those recovered at Biéville-Beuville (final Mesolithic). Those at Colombelles were initially extracted from slightly weathered ironstone layers and it is suggested here that their extraction required extra digging to reach less weathered hematite-rich material. In contrast, OIS from Biéville-Beuville have a mineralogical composition indicative of more intense weathering, which might indicate collection of surface material. The final Mesolithic raw material of Biéville-Beuville seems to have been obtained through a different mode of acquisition than that utilized during the early Neolithic. Our research allows us to conclude that all the archaeological OIS from the Plain of Caen are of local or regional origins and that Devonian (Lower Famennian, Frasnian) OIS from Belgium, Lower/Middle Devonian, OIS from the Eifel (Germany) or Mesozoic OIS from Lorraine (in the three border areas between the Grand Duchy of Luxembourg, Belgium and France) are totally lacking. Early Neolithic sites in Belgium contain no oolitic ironstone imported from Normandy. As a consequence, we can conclude that for this specific raw material, there is a lack of exchange between early Neolithic Belgian populations (Hesbaye and Dendre Springs) and the population of the Plain of Caen.
