The evolution of chipped stone industries in the “Polgár Island” from the Middle Neolithic to the Early Copper Age

“Polgár Island” is a natural elevation delimited by river banks; its flat area covers 70 sq.km The “Polgár Island” is of particular importance for the study of interregional contacts as raw materials deposits are absent in this territory. The settlement in the “Polgár Island” can be seen from the Middle Neolithic to the Early Copper Age (ALP I-IV, Late Neolithic and Tiszpolgár Culture). In this time-span changes in raw material supply, technology and organization of lithic production took place. In the Early Phase obsidian played the most important role, and contacts developed along the north-south axis. In the Late Neolithic horizon (Polgár-Csöszhálom-dűlő) the flow of obsidian was smaller, replaced by limnoquartzites. A major change in the systems of raw material supply occured at the beginning of the Copper Age, Simultaneously with changes in the direction of raw material supply, diachronic changes took place in the organization of lithic production.
