Neolithic networking and mobility during the 5th and 4th millennia BC in north-eastern Iberia

In this paper we present data from multi-isotopic analyses (⁸⁷Sr/⁸⁶Sr, δ¹⁸O, δ¹³C) of human individuals buried in the Neolithic communities of the north-eastern Iberian Peninsula. The sites researched were Bòbila Madurell, Can Gambús and Puig d'en Roca, all dated to the late 5th and early 4th millennia cal BC. The main objective was to explore chronological movement and the extent to which these communities moved and interacted with their Neolithic counterparts. The results show that the mobility of these communities was limited, as only 8.3% of the individuals exhibited non-local values. In addition, the chronological analysis confirmed their same horizon and temporal distribution. This means that they used resources and raw materials found in the immediate vicinity. It also implies that they had a certain degree of social organization and were already engaged in the trading of raw materials, some of which came from Central Europe and the Mediterranean islands.
