Copper Supply Networks in the Early Bronze Age of South-east Spain

south-east Spain have been the subject of a long-running debate. On one side of this debate we have
a model that envisages supply for much of the El Argar culture coming from a closely circumscribed
region and controlled centrally by a political élite, while on the other side we have a model of a more
decentralised supply network drawing on a wider, geographically more dispersed range of ore sources
that is lacking the same level of political control. The available archaeometallurgical data are not
entirely conclusive in this respect. While results from the existing, comparatively small body of lead
isotope analyses have been taken to support, at least to some extent, the idea of a single main source
region supplying most if not all of the El Argar culture area with copper, results from the much larger
but not easily interpreted body of minor-element analyses would appear to lend support to the notion of
a more decentralised supply. In this contribution we present new analytical data from the Lower Segura
Valley, both from local copper ores and from local El Argar artefacts, which provide new insights
relevant to this debate
