 abstract={More than 40 years ago R. Schild reported the presence of obsidian and Vistulian lithics at Rydno XIII/1959 in central Poland, and speculated that the geological source for the obsidian lay in the Tokay region of Hungary. Non-destructive energy dispersive x-ray fluorescence analysis was conducted recently on the Rydno XIII obsidian artifacts, and the data generated support R. Schild, M. Marczak and H. Królik’s suggestion (1975). The geological source of obsidian from a late Mesolithic site in Poland has been documented for the first time by instrumental data results},
