Abstract:Chert from the limestones and marly limestones of Castelltallat Formation (Ebro Basin) was widely used throughout prehistoric times in north-eastern Iberia to produce stone tools due to its properties and accessibility.A rough estimate indicates that this rock -either as raw material or as lithic products-was distributed mainly to the north of the outcrops, over an area of 6000-8000km 2 . However, other rocks in the area have similar characteristics which can lead to confusion in the interpretation of its preh… Show more
“…In order to establish the distribution area of products knapped on this flint more precisely, full petrographic, mineralogical and geochemical characterisation of the flint has been carried out (Ortega et al . 2017). Figure 5. Location of the four case studies in north-eastern Iberia.…”

Prehistoric communities carried out quarrying activities to obtain raw materials for tool production. These were produced either directly for immediate or later use by the same groups who quarried the stone, or indirectly by distributing the raw material or partially or completely manufactured products to third parties. All these procedures could be performed within a temporal and spatial sequence of variable extent, giving rise to archaeological evidence of very different types (Nelson 1991; Ingold 2012).

“…This addition will contribute to the procedures used for identifying the chemical evolution of SRO similar to what some of us developed for the so-called Campanian Bergerac flint of Nouvelle Aquitaine and the Obourg flint from Hainault (Fernandes et al in press). This will also enable us to enhance the chemical aspect of the ID card for the various gitological types in the same way that Sanchez de la Torre (2015) and Ortega et al (2017) have done for SRO resources in Catalonia. Although the importance of geochemistry in the study of materials is widely proven it must take place following the precise determination of the naturalist characteristics (Sanchez de la Torre et al 2017a;2017b), since routine geochemical analysis is not suitable for SRO because of their open and metastable nature (Delvigne et al 2017;Fernandes 2012, Thiry et al 2014.…”
In the wake of the discovery of numerous large blade workshops at Le Grand-Pressigny site (Indre-et-Loire, France), which initially aroused great interest, the mid-Loire Valley region became central to studies of flint diffusion. Despite the quality of the initial work, the widely shared view now is that the capacity for this concept to continue to provide useful archaeological modelling has diminished. Establishing real and actual correlations between archaeological objects and geological samples remains difficult, making it almost impossible to determine the source of certain materials represented in an archaeological series. In response to this problem, the French collective research project "Réseau de lithothèque en région Centre-Val de Loire" assembled about 30 amateur and professional researchers from various European institutions to work on three strategic missions:
Mission 1: establish a list of current lithotheques (“rock-libraries” or comparative collections), verify their contents and complete them if necessary;
Mission 2: link the major types of depositional environments with the properties acquired by flint through its life;
Mission 3: spread knowledge and information both within the project and to all interested persons.
The project is closely associated with similar French programs already in place in Auvergne-Rhône-Alpes and Aquitaine regions. The ultimate objective is to build a national and international community around a common project, bringing participants together regularly to share knowledge and technical expertise.
Barremian-Bedoulian flint from the Vaucluse region (western Provence, SE France), is traditionally considered one of the most significant chrono-cultural markers of the Chasséen culture during the Middle Neolithic (end of the 5th and beginning of the 4th millennium BC). Diffusion of Provençal flints became massive during the first half of the 4th millennium BC, penetrating in several neighbouring cultural spheres such as the Sepulcros de Fosa culture in north-eastern Iberia. The integrated study of the lithic assemblages from the variscite mines of Gavà (Barcelona) and its contextualization within the Sepulcros de Fosa culture in north-eastern Iberia have revealed unexpected complexity in the modes of consumption, use and status of imported Barremian-Bedoulian industries in north-eastern Iberia during the 5th to 4th millennia cal. BC transition. Local communities within this region, already controlling extraction and regional diffusion of variscite ornaments, exerted control over the fluxes of Vauclusian flint south of the Pyrenees, where it had a triple status (functional, symbolic and both). In addition, the results provide complementary data to better understand relevant aspects of the nature and organisation of Barremian-Bedoulian flint exploitation and early supply systems at the Provençal producing sites during the later phase of the Chasséen culture.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
