EGALITARIAN EXCHANGE SYSTEMS IN CALIFORNIA: A PRELIMINARY VIEW

The very early development and extent of the obsidian trade in the Near East is being increasingly documented by the discovery and excavation of Early Neolithic sites throughout the area. Since the publication of our last paper (Renfrew, Cann and Dixon, 1966), obsidians from five aceramic Neolithic sites have been analysed, and the natural source of the material determined in each case. All the results fall into the framework of groups already established. In addition, one new obsidian source has been discovered.
